Love the products!

Love the products! They have saved me thousands of hours and they are responsible for me getting a promotion at my last job, which helped me land my current position as a manager.

It's the best $100 we've ever spent!

I talked my supervisor into getting Ultimate Suite. I often deal with huge tables and matching between versions has always been a nightmare. He asked me about the new tools and I said: "It's the best $100 we've ever spent!" Indeed has saved me hours of work time. So, one big "Thanks!"

Mike Cavanagh

Incredible product, even better tech support…AbleBits totally delivers!

I use AbleBits every day and keep finding new uses. Changing jobs, I get my new employer to cough up the very reasonable cost of this software. There're things I just can't complete any other way in large datasets. My coworkers think I'm a wizard. But I'm just a religious user of AbleBits.

Deborah Bryant

Anyone who works with Excel is sure to find their work made easier by Ablebits

I've been using Ultimate Suite for almost a year and found it invaluable for my projects. I like the ability to merge tables based on 1 or more attributes, transpose columns and rows, and to transform data with Cell Cleaner utility. Plus, Ablebits' support is reliably fast and courteous.

Jackie Lee

Excel is at its best now

Ever since I found your add-ons, it has been a life saver or should I say a major time saver. I have bought two packages for both work computers. Excel is at its best now because of you. Thank you!

KUDOS to you guys for solving a problem that our IT department doesn't understand

Our IT thought they know how the sales department should function and destroyed some data files. With AbleBits I was able to regenerate my database in a few clicks. This was AWESOME. KUDOS to you guys for solving a problem that even our IT department doesn't understand.

Erik Peterson

AbleBits suite has really helped me when I was in a crunch!

Having AbleBits suite really helped me when I was in a crunch! It was intuitive and saved time on my job! Now I'm finding other capabilities I wasn't aware of, (first needed the easy merge capability). The other features are valuable time savers as well. Thanks for the product!

Nelda Fink

Dave Brown

I don't know how to thank you enough for your Excel add-ins

I don't know how to thank you enough. I stumbled upon your site figuring out how to merge 2 tables. When I saw a free trial, I thought how well is this going to work? I downloaded it and am AMAZED. I don't know how I lived without it. THANK YOU for making my life easier.

Jennifer Morningstar

Anybody who experiences it, is bound to love it!

Anybody who experiences it, is bound to love it! There're only 2 ways to "exploit" Excel's potential: be a geek or embrace Ultimate Suite. Why waste time on routines that can happen with a click of a mouse? Make use of Excel's capabilities without wasting time and energy.

Kumar Nepa

Brad Gibson

The best spent money on software I've ever spent!

I just have to tell you that I love your AbleBits Collection. I can't tell you how much time it has saved me, particularly Merge Tables Wizard, Duplicate Removers, Merge Cells Wizard, and Split Names. This was the best spent money on software I've ever spent!

Patrick Raugh

It is like having an expert at my shoulder helping me…

I feel that Ablebits has people like me in mind with software development. It's like having an expert at my shoulder helping me work more efficiently. Now I have more time to goof off at work. Uh, that last statement isn't true - I just have a lot less stress as things go so much smoother.

Linda Shakespeare

Your software really helps make my job easier

Your software really helps make my job easier. I don't know what I would do without Duplicate Remover, I use it several times a day for every project I work on. Thanks for making my life easier.

Frequently asked questions

What is Random Generator and what do I need it for?

With the Random Generator for Excel tool you can easily fill a range of cells with any random data. In just a few clicks you will:

  • Generate unique random numbers, integers, dates, Booleans, reals.
  • Create random passwords of a given length with different charsets (e.g. A - Z, 0 - 9) or special symbols.
  • Fill the selected range with any random values from your custom list.

How to generate random numbers in Excel without duplicates?

With Random Generator you can get random integers or real numbers with or without duplicates.

Run the add-in, select your range of cells, choose the needed option, and specify the minimum and maximum values. If you need random numbers with no repeats, check the Unique values checkbox. Click Generate and get your random values created.

Please find a more detailed description here.

Can I use the add-in as a password generator?

Sure! Select Excel cells, where you want to see your random passwords. Open the add-in pane and choose characters required for your password. It can be A - Z, a - z, 0 - 9, space, etc. You can also enter any other characters into the Custom field. Set the string length which may be up to 99 characters.

Find more information here.

How to generate random dates in Excel?

The Random Generator tool has a special option for dates. You can specify a range for dates and choose workdays, weekends, or both. If you need the created range of values to have no duplicates, tick off Unique values.

Does the utility work as a code generator?

Yes, Random Generator for Excel creates random strings by mask.For example, if you need to generate phone numbers, you check the digits set and use this mask +1-???-???-????. Click Generate and you will have the fake telephone numbers all across the selected range. Of course, apart from phone numbers, you can use this option for producing any other code types, for example coupons, RGB colors, product IDs, zip codes, SKUs, etc.

Find step-by-step instructions here.

Can I fill the range with random values from the custom list?

Of course. There is an option in the add-in called Custom list, which randomly fills the range with values from standard Microsoft Excel custom lists or from your own list.For example, you have 50 names and need to pick random 10. Just add all 50 names to your custom list, select 10 blank cells in Excel, click Generate and get 10 random names picked from your Excel list.

Besides, the utility allows to create a custom list from your random data. Suppose you have a list of names in a worksheet. You select this list and click New list. That's it! Just one click and you have a new list added to the Random Generator. Now you have it among your Excel custom lists.

Find more information here.

What is the algorithm used in the Random Generator utility?

Our Random generator add-in uses the reliable Mersenne Twister algorithm. We use version MT19937 that produces a normally distributed sequence of 32-bit integers and has the following advantages:

  • It generates a better pseudo-random number sequence than the RAND() formula in Excel and the rnd() function in VBA.
  • It has a big period of a nonrecurring random number sequence:
    2^19937-1.
  • It has gone through numerous tests on statistical randomness, including the NIST Statistical Test Suite and Diehard tests. It passed most of, though not all, TestU01 Crush randomness tests, which are even tougher.
