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!

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

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!

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 Compare Tables for Excel?

The Compare Tables for Excel tool helps to find matches and differences between two columns, lists, or tables. You choose the ranges to compare and one or several key columns. Compare Tables can identify matches (duplicates) and differences (unique values). You can select the found entries, copy or move to another worksheet or workbook, remove duplicates, highlight dupes and uniques with color.

Can't I compare lists for differences without any add-ins?

You can try to identify matches and differences between two lists with a formula, or you can use Excel conditional formatting to highlight duplicates. The problem is that a universal formula to compare data in Excel does not exist. Every time you will have to build a new formula depending on whether you want to check for duplicates or unique values, with or without first occurrences, etc. Compare Tables for Excel can handle all these scenarios and makes the process of looking for duplicates and unique values fast and easy.

Why not deduplicate in Excel using the built-in Remove Duplicates tool?

The Remove Duplicates feature available in Excel 2007, Excel 2010, Excel 2013 and Excel 2016 can only search for duplicates in one table. It cannot compare two columns for differences and matches. Nor can it highlight, select, or copy dupes, only remove them.

How to find duplicates in Excel with this tool?

For starters, please make sure both tables you want to check for duplicates are open in Excel, they can be in the same or different worksheets or workbooks.

Click the Compare Tables icon on the Ablebits Data tab, and do the following:

  1. Select your main table. Since Excel won't let you undo changes, it makes sense to select the Create a backup copy of the worksheet checkbox.
  2. Select your second table.
  3. Choose what you want to find: duplicates (matches) or unique values (differences).
  4. Select the key columns for comparison.
  5. Choose the desired action for found data: select or highlight cells, remove duplicates, identify in a status column, copy or move the results to another location.
  6. Finally, click the Finish button and have your comparison done.

Sure. To find duplicate lines in two tables, select several key columns on step 4. In this case, the add-in will show you duplicate rows. Once the rows are found, you can remove duplicate lines in one click.

To remove duplicate records, on step 3 select to search for duplicates. On step 5, choose the Delete values option. As the result, all duplicates will be removed from the main table.

Can I find dupes in two Excel tables without removing them?

Of course, you can. The add-in offers plenty of options to deal with dupes apart from removing them. You can get them all selected or highlighted with color, copied or moved to another worksheet or Excel file. Also, you can add a column to your main table to identify duplicate and unique rows.

How to compare two lists in Excel and find unique values?

To find the differences between two tables, on step 3 select to check for unique values. On step 5, decide whether to select or highlight the unique values, or mark with a status column.
