Overview
The user-proven #1 solution for managing duplicates and uniques across your spreadsheets. More than 2,400,000 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.

WHY THIS ADD-ON IS BETTER THAN OTHER KNOWN METHODS

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

HOW REMOVE DUPLICATES WORKS

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

WHAT'S NEW:

***** V1.13 (8 Oct 2021) *****
Improved:
- Remove Duplicate Rows, Compare Sheets: significant performance improvements in processing large amounts of data.
- Minor UX improvements.

Fixed:
- Remove Duplicate Rows: new scenarios pulled settings from the very first saved scenario.
- Compare Sheets:
    1. Scenarios didn't work if the second spreadsheet recorded in the scenarios was removed from Drive.
    2. Scenarios errored if the sheet had fewer rows than was mentioned in the scenarios. 
    3. When you changed the second sheet in the scenario, it still used the table that was saved in the scenario initially.
    4. New scenarios contained settings from the very first saved scenario.
- Minor UX and UI fixes.

***** V1.12 (5 May 2021) *****
★ New features ★ 
- Scenarios are finally available for Combine Duplicate Rows and Compare Sheets. Make sure to visit the related help pages for more details.
- Compare Sheets. If sheets of interest are in separate spreadsheets, you can add them for comparison from Drive straight from the add-on.
- Remove Duplicate Rows, Compare Sheets, Quick Dedupe. New action with found values is available – delete entire rows from the sheet.

Improved:
- Auto-select the entire range by clicking the gray rectangle between column and row headers.
- The scenarios menu changed a bit: instead of 2 separate menus to 'Run' and 'View & manage', you will see a list of all saved scenarios under the corresponding menu item. Pick the scenario you need, and you'll be able to start or edit it.
- The width of the status column now expands automatically to fit its contents.
- Minor UX improvements.

Fixed:
- Couldn't process data if the range referred to columns only (e.g. A:D).
- Didn't work if you run the tools from a sheet with its own separate chart.
- Remove Duplicate Cells:
    1.  Fired an error if you selected an entire column as a custom location for the results.
    2. Couldn't insert the result into a custom column.
- Compare Sheets:
    1. Accepted incorrect ranges.
    2. You couldn't change the range after pressing 'Cancel' in the pop-up notifications.
    3. The 'Auto detect' button didn't revert matching columns to their default state after picking them manually.
- Combine Duplicate Rows: worked endlessly if the option to create a backup copy was selected.
- Scenarios:
    1. Didn't work if run on the sheet with blank headers.
    2. Didn't work right after making changes to scenario settings in the 'View & manage scenario' menu.
    3. Didn't work with tables without headers when the range referred to columns only (e.g. A:D).
- Minor UX and UI issues.

***** V1.11 *****
★ New features ★
- Quick Dedupe. This one-step tool will instantly find and eliminate duplicates in your table. It colors and deletes, copies and moves dupes to a new sheet, as well as marks them in a status column.

Improved:
- UX: auto-select behaviour. Now the add-on highlights only the table where your cursor stands rather than an entire used range.
- UI: images as hints are added. These schemes show how certain settings work. Each option has an "i" button next to its name. Click on it to open a related scheme within the add-on.
- How do you like the new Ablebits logo? ;) Other footer icons have also been updated.

Fixed:
- Combine Duplicate Rows. MODE and STDEV(P) returned the contents of unique cells. COUNT also processed cells without dupes incorrectly.

- Minor improvements.

***** V1.9 *****
★ New features ★

Improved:
 - Minor improvements and text adjustments.

Fixed:
 - Remove Duplicate Cells: copy and move results to a new location.

***** V1.8 *****
★ New features ★
 - Find duplicate cells. You can find and process duplicate or unique cells within the selected range.

 - Small screens and minor issues UIs.
 - Performance. The new version of the add-on processes colored cells faster.

TAKE NOTE: This ONLY scans for duplicate ROWS. My table organization was done in blocks, rendering this add-on useless for me. It does work, though. Would really like to see a feature that scans for duplicate individual cells.

Great tool for finding unique/duplicate data out of several data sets. Small thing, but some of the definitions when comparing columns (for example) are confusion and I run it for the column I know are duplicates vs the column where I don't know they are duplicates. So at times have to run it twice to get the output that I need. Aside from that small piece of product feedback, works great every time!

OK, but clunky. Descriptions of selections you want are unclear, plops status column right in the middle of the spreadsheet (although I'm not sure an edge would be better). Would like to see the author polish this app so it's more streamlined and clear.

They are charging a subscription for a tool that only runs at your own computer, without any ongoing use of this company’s resources whatsoever. Don’t fall for this; there are multiple free alternatives. Edit: The add-on maker’s response to this review ignored the main point that the functionality of the add-on does not use the resources of the maker whatsoever. The add-on, once added to a user’s Google account, only makes use of the user's own resources. There is nothing that justifies an ongoing subscription. Their response (since removed) was misleading and was another piece of evidence to these people who are now managing this add-on’s sales being dishonest extortionists.

It didn't give me a finish button. I got it all set up and there was no finish button or continue or back button on step 4. I use firefox. No Script was set to allow ablebits.

I was a bit irked that this is a standard document function that had to be purchased separately (and as a subscription which is kind of bull) but I can tighten the belt and shell out a few bucks. however the fact that it suddenly doesn't work and there is no way to report it or request assistance is pretty frustrating. Just spent an hour doing all restarting and refreshing I can think of since I desperately need this to work in order to proceed with my JOB today and still no go, so looks like I'm going to have to figure something else out.

I would consider donating a buck or few for a life time license, but to ask for a subscription? Have you lost your minds?

Works great, except you need to have the individual sheets be in the correct order for the 'Compare Sheets' to work. Just put the first sheet you want to select as the farthest to the left, and the second as the next one, and it works fine. Reverse them, and it seems to show no results... Otherwise it's an elegant solution!
