The user-proven #1 solution for managing duplicates and uniques across your spreadsheets. More than 600,000 installs and thousands of happy users!

Spotting duplicates in hundreds of rows of data can be a pain in the neck. Luckily, Remove Duplicates was designed to do it for you on the fly so that you can spare your time for more meaningful tasks.


Remove Duplicates is easy to use and comes with a wide range of options for handling duplicates and uniques. This is something you just can’t find in other available methods such as Google App Scripts, =UNIQUE, or conditional formatting:

  • No need to use the Script Editor, macros, formulas or coding
  • Duplicates deleted automatically right away, saving your time
  • Search across two sheets and consider text case if needed
  • Save your search as a scenario for later use


The add-on offers the following five features performed in just five or less simple steps — no coding, no formulas required:

  1. Find duplicate or unique rows

This feature is designed to identify duplicate or unique rows within a Google Sheet and manage them further (highlight, remove, move to another tab and even more).

  2. Quick Dedupe

This is a one-step alternative of the first feature. While offering the same options to process duplicates (remove, highlight, copy, move, label), it immediately deduplicates your entire table.

  3. Find duplicate or unique cells

With this feature, you can find and highlight identical or unique content within cells in just a few clicks. Duplicate cells will never escape your attention again. 

  4. Compare columns or sheets

Multiple tabs and columns are often used to keep track of records as they change over time. This tool will help you easily compare two sheets or columns and quickly spot alterations and identicals.

 5. Combine duplicate rows

If removing duplicates is not an option, you can merge cells from duplicate rows with this tool. Just pick your columns with dupes, set delimiters to your liking, and combine related values from other columns. Or benefit from 14 built-in functions to calculate numbers from duplicate rows instead.

Each of the features empowers you with an array of actions to take on the content:

  • Highlight duplicates or uniques with your favorite color
  • Clear rows/cells
  • Delete rows/cells
  • Copy to another spreadsheet
  • Move to another spreadsheet
  • Mark as duplicates/uniques in a new column
  • Merge cells from duplicate rows using delimiters
  • Calculate numbers from dupe rows with 14 functions

The add-on also offers a variety of additional unique and duplicate scanning options: 

  • Case sensitivity
  • Inclusion/exclusion of blank cells and rows
  • Saving your session settings as a scenario for later use


With Remove Duplicates, you can find and delete duplicate and unique rows and cells for free within the 30-day trial period. 


You can buy the annual license for the add-on for just $33.60 or use Remove Duplicates forever for a one-off charge of $59.90. 

All payments are secure and include an unconditional 30-day money-back guarantee.

Love this add on! It allows me to work so much more efficiently. It was the only purchase I made on Black Friday. I am so glad I caved and bought it!

This was a free add-on when i first installed it like 3 years ago. Now they want a yearly subscription of $19.99/year -or- $59.99 for a "lifetime sub". Sorry -- nothing last forever, so that's a hard pass on the "lifetime sub"; and $19.99/year for what exactly?? It has not gone through amazing changes or updates and has the same basic functionality. Again, hard pass. This should be a free add-on as it was.

Very good extension. It can look for duplicates, mark them in color or add another colum so you can filter and delete them. It searches for 1st occurances duplicates, uniques, and move cells to another sheet. It works on large data sheets as well. Google has a remove duplicates function, but it only removes duplicates for a single column, as far as I could tell. Doesn't do anything else, you can't mark the cells and delete rows. Quite a useful extension. Free alternative here: slightly less UI friendly though, and with less functionality

Yeah, but Google doesn't mark or delete rows, or search for 1st occurances, or uniques. This add-on has far more functionality than what Google offers. There is a free alternative here though: with slightly less functionality, and clunkier UI. Still, it's free.

Hello George, Our Remove Duplicates offers far more advanced functionality. It colors, copies, moves, clears or deletes not only dupes, but also uniques and the 1st occurrences. It scans not only rows, but single cells as well, and compares sheets and/or columns for dupes/uniques.
