Overview
The user-proven #1 solution for managing duplicates and uniques across your spreadsheets. More than 3,300,000 installs and thousands of happy users!

Checking for duplicates in hundreds of Google Sheets rows can be a pain in the neck. Luckily, Remove Duplicates is designed to do it for you on the fly so you could spare your time for more meaningful tasks.

WHY THIS ADD-ON IS BETTER THAN OTHER KNOWN METHODS

Remove Duplicates is easy to use and comes with a wide range of options to handle duplicates in Google Sheets as well as 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
  • Find duplicates in Google Sheets automatically right away, saving your time
  • Compare two columns or sheets even from different files
  • Consider text case if needed

MAKE THE TOOL FIND DUPLICATES AUTOMATICALLY

  • Save your search as a scenario for quick use later
  • Schedule scenarios so they run daily at a certain time

HOW REMOVE DUPLICATES WORKS

The add-on offers the following 5 features performed in just 5 or fewer simple steps — no coding, no formulas required:

  1. Find duplicate or unique rows

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

  2. Quick Dedupe

A one-step alternative to 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

Find and highlight duplicate or unique cells in just a few clicks. Identical cells will never escape your attention again.

  4. Compare columns or sheets

Easily compare two sheets or columns and quickly find duplicates or uniques in Google Sheets.

 5. Combine duplicate rows

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/move 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

EXTRA unique and duplicate scanning OPTIONS:
  • Automation:
     1. Saving your session settings as scenarios for later use
     2. Schedule your scenarios so they run automatically 1-2 times a day
  • Case sensitivity
  • Inclusion/exclusion of blank cells and rows
