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 case-sensitivity supported
• Option to save your search as a scenario for later use


The add-on offers the following four 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. 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.

3. 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.

4. 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 all 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.
