Hooked on this product
I've been using the excel add-on program Ablebits for over a decade. It is an absolute must-have tool for me. Over the years I've shown it to many co-workers who also get hooked on how much easier it makes worksheet tasks. Combining data from other worksheets and duplicate remover are the 2 features I use the most.
I've been using the Ablebits product for several years
I've been using the Ablebits Excel product for several years. It is a lifesaver since my life revolves around data and spreadsheets. With the variety of tools and ease of use, there are no tasks I haven't been able to accomplish. Also, their customer service has always been very responsive and provide great answers, plus additional tips, or information.
AbleBits automated my entire Excel life
AbleBits Ultimate has an endless amount of features that I'm still figuring out after 6 months of use. I got tired of adding in formulas myself, multi step processes to try and merge tables, and the dreaded formatting issues I always had to deal with. Everything in AbleBits completes the automations with wizards and easy to use features. Thank you for everything and will continue to recommend this add on to everyone!
Ablebits Ultimate Suite turns Excel into what it should have always been
Ablebits Ultimate Suite turns Excel into what it should have always been. I've had this product for about 5 years and won't use Excel without it. I frequently need to take data from multiple sources and coalesce it into large import files. The Merge Table function is a gamechanger for these tasks. The Substring functions are also an exceptional piece of kit for streamlining data. There's a limit to Excel's data management capabilities, but the Ultimate Suite tools take it to a whole new level.
Inexpensive with TONS of value!
I have been an ablebits user for many years, and while sometimes people tell me you can do everything it does natively in excel - ablebits makes it EASY. I can consolodate and combine things using a natural language, I can see the results of something before I do it. It is an inexpensive tool that is incredibly valuable!
Can't live without it
I love the program, and I can't imagine using Excel without it! We do a lot of database management in excel and Ultimate Suite saves us endless time. I use it a lot for merging columns, trimming spaces, merging spreadsheets, converting casing. The program pays for itself. Thank you for all your efforts and support.
Ablebits occupies a unique place for Excel users
Ablebits occupies a unique place for Excel users as there is no comparable product out there. I have found the duplicate remover and merge duplicates modules particularly useful. It is very user-friendly and the support response has been rapid and helpful when I have contacted them. There is so much information on their website explaining how to achieve outcomes in Excel. Highly recommended!
Absolutely worth every penny!!!
I use Ablebits Ultimate Suite in Excel everyday and the amount of time saved is amazing. Things that used to take 10 or 15 minutes now can be done in under a minute with this add-in. HIGHLY recommended! Customer service is quick and the staff is very knowledgeable and courteous.
Just one great product and a great company!
I have been using Ablebits since 2016 and it has been a most useful tool. And if that isn't enough, their support should be the model for all customer support throughout the industry. Over the years I have had problems or questions and they have resolved all quickly and politely without making you feel belittled. Just one great product and a great company!
A wonderful feeling to be amazed by a product
I paid for the personal edition out of my salary for my own use. It was not purchased by my organization, and I truly think that this is money well spent. I have not had one moment of regret – just the opposite. Each time that I use AbleBits I experience pleasure that I have spent my money wisely and am getting more value for my money than I could have thought possible. What a wonderful feeling to be amazed by a product each time that I use it even after daily using it for over a year.
The Ablebits Excel add-in is an absolute must have
If you find yourself working with spreadsheets even a couple times a day then you need to stop what you are doing and buy this add in! The Ablebits Excel add in is an absolute must have. I have been using it for years now and can’t even start to quantify how many hours, days, weeks, this has saved me. Adding to the awesome product is an awesome support team. Anytime I’ve ever had a problem or question they are prompt to reply providing nothing but useful information.
The software is the real deal
I can't tell you how many times I was scratching my head on something I needed to do in Excel and would suffer through a cumbersome way to do it, then I found Ablebits. More often than not, they have an elegant and easy solution for what I need to do. They have saved me countless hours and headaches. Their customer support is top notch too - very quick and HELPFUL. These folks are the real deal. The software is the real deal.
Great product - even better service
The Ablebits Excel addin is a real time saver. If you are doing anything complex with data sets in Excel and want to do things like de-dupe, check and cross-reference, this is a game changer. Well worth the money. Above that, the service is really excellent. Send an email and you get a reply pretty much within the hour. Very impressed and can't recommend enough.
It's a lifesaver!
I have been using the ultimate suite for a few years and its a lifesaver!! I use it all the time to merge sheets and it saves me so much time! The support is also excellent. They are in a different time zone than I am (I am EST) but I always hear back in less than 24 hours. The price is reasonable and the product is good. I highly reccomend it!
I would be lost without it
I use Ablebits add on for excel several times per day and would be lost without it. For us it is especially useful for highlighting duplicates, removing duplicates, comparing tables, comparing sheets, deleting blank cells. It does much more than that, but these are the most popular uses here. It is well worth installing. Thanks!
Ablebits has saved me countless hours!
Ablebits has saved me countless hours! Every time I confront a repetitive task in Excel, I look to my Ablebits tool bar for a solution. I almost always find that the geniuses at Ablebits have developed a seamlessly integrated Excel solution. I'm still discovering powerful tools in this awesome collection of widgets.
Always well within 24 hours
Besides the fact that this is impressive software that just works as you’d expect it to work (no overpromising and underdelivering), what’s even more impressive is the support that has Ablebits has given me over the years. I’ve very seldom had to call on support (usually trivial admin matters) but when I have, their responses have been comprehensive and always well within 24 hours. Well done Ablebits!
A life and time saving tool with great customer service!
A life and time saving tool with great customer service! I have used Ablebits for quite a few years and have been truly blessed by it. I take it with me with every new computer refresh I go through, and customer service is always able to provide me with any assistance that I need, hassle free. A product could be good, but when they have great customer service, they are deserving of a five star.
Can't go without it
I have been using AbleBits since probably 2008. First with their free version and then I purchased their paid version a few years ago. I just upgraded again. The program makes it so much easier to trim spaces and perform other tasks in Excel. I'd say I probably use their Excel add-in at least weekly if not daily. I recommend them for your Excel needs.
It is a game changer!
I refuse to use Excel without Ablebits Ultimate Suite! It is a game changer! Compared to similar tools in the market, Ablebits is more user friendly and easier to understand than the others. And if you need help, their service support team is top notch and insanely fast to respond. You don't need to be an Excel geek to use this product, but you will feel like one if you do!
Abelbits is a very useful program
Abelbits is a very useful program. I use it constantly for the state function,Pivot table, transposing key columns, compare, consolidating spreadsheets, and duplicate remover. Customer support is very friendly and responds quickly especially when needing to do a new installation of a PC or upgrading. I highly recommend this product.
I highly recommend the Ablebits Ultimate Suite
I'm a business coach and number crunching is not something I do a lot. Therefore there must be a lot more value in Ablebits suite than I will ever use. I find that the tools I wish were in Excel are all in the Suite and the level of support by the Ablebits team has been very quick, thorough and complete. I highly recommend the Ablebits Ultimate Suite.
We discovered a gold mine!
When we discovered Ablebits 10 years ago, we discovered a gold mine! It provides a simple, straightforward way to work with multiple spreadsheets and excel files without having to figure out formulas. When something happens in our system and we "lose" Ablebits, my staff nearly panics until we can get it back up and running. We consider this an essential tool in performing many, many tasks in our jobs.
Would recommend it to anyone who works with Excel
We have been using the Ultimate Suite for a year and really appreciate the time it has saved us in getting our lists ready for our updates. I could not believe how fast AbleBits got back to us. They are very fast to help you with a problem and showing you how to take care of it. They are very knowledgeable with their product. I would recommend them to anyone who works with Excel a lot.
Save hours of your life
This product very literally saves me HOURS in time compiling or updating information from several Excel sheets or files into one using just one matching column, and cleaning into a usable endproduct. There are so many features that simplify otherwise timeconsuming and tedious tasks that it makes working without the Add-In seem impossible. Highly recommended!
Ablebits makes magic
Ablebits is the "magic" that I use each week to help me accomplish nearly all of the tasks for which I am assigned. In a few simple clicks of a trackpad, I can create spreadsheets that help us review our impact and identify ways to continue to improve. The process is so easy and customer support has been critical; helping me make the most of this incredible tool!
I have found the Ablebits app and website to be extremely useful
My work requires that I write financial reports exceeding 200 pages based on analyses done in Excel. I have found the Ablebits app and website to be extremely useful. Some specific tools I have found useful are the "find broken links," select by color," visualize, "formula translator" (beta version), "spell number," and, best of all, the most reliable workbook manager I've ever used.
Extremely useful add-in with extensive functionality
I purchased and installed Ablebits for Excel. I have found it to be extremely useful in supplementing the capabilities of Excel – the functionality is very extensive. More importantly, I have found the support from Ablebits to be invaluable – patient and thorough. I definitely recommend Ablebits if you want to push the limits of your use of Excel.
Ablebits Ultimate Suite for Excel is invaluable if you work with spreadsheets
Ablebits Ultimate Suite for Excel is well worth the money. This add on has saved me countless hours of work with just a couple of the features. I have to take client lists which are often not in the format I need and make them fit into the format we use. This is invaluable for merging spreadsheets with duplicate values, as well as merging multiple cells into useable data. You will not regret this purchase.
The best add-in for anyone
The Ablebits Ultimate Suite for Excel is without question the best add-in for anyone using spread sheets! Great tech support, no glitches, works fantastically well - and it really is useful. Lots of features that should be built-in to the platform and aren't. I've used it for years with terrific results. Thanks!
Exceptional product and service
Exceptional Product and Service: I have used Ablebits for several years, solving incredibly difficult problems in Excel, problems well beyond my coding and formula development skills, and each time, Ablebits provided an easy-to-use solution. And, when I needed help, response time was practically instantaneous, not an AI chatbot, but a real person who solves real problems.
Excellent product and support!
Being a user of the "Ultimate Suite" since 2016 and processing 100'000s of datasets, I am utmost convinced of the product. And what is also excellent: is the support. Every question asked was answered very quickly and competently. You provided a free upgrade unasked - stunning! Thank you, Ablebits team, for your excellent product and support!
It is a productivity multiplier!
Since first installing Ablebits Ultimate Personal over 18 months ago, I have learned a whole new level of data management. It is a potent tool that's very easy to learn and use. It is a productivity multiplier!! Likewise, the Ablebits Support Team is highly professional, rapid responders, and helpful, a rare treat these days!
If that's not good service, I don't know what is
Who wants to learn VBA? I know I didn't when I was forced to learn it. Then came Ablebits, and I can never go back. Imagine someone giving you a flip phone now, in 2022. That's what it's like living without Ablebits. I had an issue where it was crashing in Excel, and I was distraught. After sending my feedback, I was greeted with an email and an updated key for the latest release, before I even made it that far in my troubleshooting. If that's not good service, I don't know what is. Can you guys just run all of our other vendors?
My Excel life changed a lot… for the better!
I believe it was around 2007-2008 when I discovered Ablebits and its table merge add-on. Since then, my "Excel life" changed a lot… for the better! I use it alongside other tools in the Ultimate Suite on a regular basis and have licensed it for people in my BD team. It is an invaluable tool!"
Well worth the price of admission
Well worth the price of admission. If you're doubting it, try it out. Even uninstalling is a breeze. I got this recommended from a co-worker for helping clean up duplicate data and manage complex editing. Went for the free trial, and was blown away. Better still, I had some trouble reinstalling things when my system got wiped. Support was on top of the issue fast and had me going again in a hurry. Incredible stuff.
Ultimate Suite is a treasure chest of useful tools
Ultimate Suite is a treasure chest of useful tools. I bought the it for the "Merge Tables tool", and it is worth the purchase price just for that. The other features I use are too numerous to mention. Ablebits makes a breeze of many tasks that would take a LOT of time to do using just formulas. It has revolutionized my work flow. And customer service is excellent.
The best tools. Exactly what I needed
Ablebits Excel tools were exactly what I needed. We even recently updated to the newest version. Before finding Ablebits, I would have to spend two to three hours comparing two different workbooks each month. Not to mention the time I would have to spend combining cells with multiple lines of text. Ablebits has saved me time effort and I'm very grateful.
AbleBits has been a huge time saver
AbleBits has been a huge time saver for cleaning up client-provided lists. With just a simple click we can quickly and efficiently trim spaces, split names, standardize case, and combine related sheets. Plus it's great to know there are so many other powerful tools in the software that are available whenever we need it.
That one program has given me years of convenience
It's been years since I was desperate to be able to do additional functions in MS Excel and could not figure out how. I did an internet search - found Ablebits and that one program has given me years of convenience. I own my own business which always has been remote and using our CRM and our client's databases all depend on MS Excel to add data. I don't know what I would have done without this program. Customer Support even now is the best I have experienced. Thank you all for being there for me when other companies don't care.
Ablebits is a dream come true for any Excel user
Ablebits is a dream come true for any Excel user working with data. I have used AbleBits for many years and thanks to regular updates the product has become a fantastic, time saving tool that no Excel user dealing with large data can do without. Your support deserve a special mention as it is prompt and always available.
This add-in is really valuable for a very reasonable cost
Ablebits Ultimate Suite for Microsoft Excel has been a time-saver and an excellent addition for my large data requirements. Rarely do I find a product that warrants spending on Excel, but this add-in is really valuable for a very reasonable cost. It installed like a charm, is intuitive, and I found customer service to be very responsive and helpful.
We couldn't imagine being without this tool!
Managing and working with data has never been easier once we began utilizing Ablebits! The tool eliminates the need to learn complex excel formulas and provides straightforward tools to significantly increase our efficiency. What used to take a day now takes one hour. It's easy to use and the support the Ablebits team provides is high quality. We couldn't imagine being without this tool!
Just want to say that I LOVE your Ultimate Suite Excel add-on
Just want to say that I LOVE your Ultimate Suite Excel add-on and would have quit my job had a colleague not recommended it to me. It has exceeded every expectation. I also want to give a shout out to someone named Ekaterina Pechyonkina, who was a tremendous help to me when I needed to migrate (same root word as migraine) from a desktop PC to a laptop. Please know that both your product and your people are making life better for those of us working with information. Thank you!!
In the first 30 minutes of using Ablebits, I have already found at least ten different tools that will save me hours each month
I consider myself a high-level Excel user and often find myself reaching the outer limits of what Excel is capable of without some convoluted workaround, VBA, or writing a Python program. In the first 30 minutes of using Ablebits, I have already found at least ten different tools that will save me hours each month. I work with a lot of complex and very messy datasets, and Merge Two Tables, Combine Sheets, Merge Duplicates, Split Table, Trim Spaces, Change Case, etc. will make my life SO much easier. I am a very satisfied customer.
Your Ablebits are truly amazing
Your Ablebits are truly amazing, and better than Unix sed or awk, that is if my 73-year old memory is accurate, which is debatable! HA! It took fantasy football to get me to really explore the capabilities of Ablebits. I’ve won my league three of the last six years! I warned those whippersnappers that a retired IT guy with spreadsheet skills was going to be a problem!
Ablebits has allowed us to reduce timescale from hour to around 5-10 minutes
PRS use third party applications to share internal spreadsheets with a digital app based system to our staff & clients. The system primarily uses CSV format. We use Ablebits for ease of combining these type documents. Previously this task was undertaken manually (taking up to 1 hour per task). Ablebits has allowed us to reduce this timescale to around 5-10 minutes. In addition, the Ablebits team are extremely helpful & very quick to respond to queries.
This software is by far the best I have ever purchased
In my line of work, this software is by far the best of any software/addon I have ever purchased/used. There is no close competition. My personality is such I don’t recommend any product/store, etc. Your product is the exception. I have recommended this product to a few and they have come back and thanked me.
Keep up the good work.
This product changed my working and investing experience
As a macro strategist and investor I deal in a large volume of data which I translate to a significant number of charts which I use then to interpret macro-economic trends, markets and investment opportunities.

KUDOS to you guys for solving a problem that our IT department doesn't understand
After our IT department thought they know how the sales department should function and destroyed some data files. With the help of Able Bits I was able to regenerate my database in just a few short clicks. This was AWESOME. KUDOS to you guys for solving a problem that even our IT department doesn't understand. As a leader in the sales department I need my data to grow sales.
AbleBits suite has really helped me when I was in a crunch!
Having AbleBits suite has really helped me when I was in a crunch! It was intuitive and really saved me time on my job! Now that the crunch is over, I'm finding there are other capabilities in the suite that I was not really aware of initially, (I originally only needed the easy merge capability). And those other features will / are valuable time savers as well. Thanks for the product!
I love the program, and I can't imagine using Excel without it!
