How To Remove Duplicates In Google Sheets

What Is A Google Sheet?

Google Sheets is spreadsheet software that is included in Google’s free, web-based Google Docs Editors suite. Google Sites, Google Slides, Google Drawings, Google Docs, Google Forms, and Google Keep are all part of the program.

Google Sheets is available on many platforms such as a web application, a smartphone app for Android, iOS, Windows, BlackBerry, and a Chrome OS desktop application. The software supports Microsoft Excel file formats.

Users can build and edit files online while interacting in real-time with other users. The user’s edits are registered, and a revision history shows the changes.

How To Remove Duplicates In Google Sheets

When some new data set is imported into a spreadsheet, duplicates in google sheets can be created or through a simple human data entry error. To remove duplicates in google, allow the application to delete copies rather than manually searching each line for information added multiple times.

To remove duplicates in Google Sheets, you can use a built-in feature, a function, or a third-party add-in. Continue reading to find out how to remove duplicates in Google Sheets.

  1. Delete Duplicates in Google Sheets Using Conditional Formatting

You could come across large spreadsheets in Google Sheets where you have to deal with many duplicate entries. Conditional formatting makes highlighting and deleting duplicates a breeze. We’ll show you how to locate and delete duplicate entries in Google Sheets in this guide.

The Conditional Formatting feature isn’t designed to get rid of duplicates. You can use this feature to make them stand out. As a result, you’ll need to complete two measures to remove it:

  • It will help you find duplicates and highlight them.
  • Remove any duplicates.

Let’s learn how to highlight duplicates in a single column before learning how to delete duplicate entries from Google Sheets. Follow the steps below.

  • Pick a column in your spreadsheet in Google Sheets.
  • Select column A then goes to “Format” and then “Conditional formatting.”

  • Let’s say you want to make a single column stand out by highlighting duplicates. Choose a column range, such as B1:B.

  • When you’re done, click Done to see the duplicates in a single column highlighted.
  • If you need to do it for column C, the formula becomes =countif(C1:C, C1)>1, and so on for the rest of the columns.

Highlight duplicates in multiple columns

  • Consider the following scenario: If you want to remove duplicates in two columns or multiple columns:
    • TOPICS (A1:A), WORDS (B1:B), PRICE(C1:C), PAYMENT STATUS (D1:D). 
  • Select the data range that will include the columns you want to delete. As a formatting law, choose “Custom formula is” and use the following formula COUNTIF:

=(COUNTIF($A$1:$A,$A1)>1)*

(COUNTIF($B$1:$B,$B1)>1)* 

(COUNTIF($C$1:$C,$C1)>1)* 

(COUNTIF($D$1:$D,$D1)>

  • The values in the formulas correspond to the columns you choose.
  • Duplicates will be highlighted on different conditions:
  1. Delete The Duplicates in Google Sheets Using an Add-on

As a rule, Google Sheets comes with an extensive library of different add-ons to address any issue or concern. Both of the duplicate elimination add-ons serve the same function. 

One of the best add-ons for removing duplicate records from your dataset is AbleBits’ Delete Duplicates.

You must first add an add-in to your Google Sheets document before you can use it.

The following functions are also possible with this add-on:

  • Fill in the blanks with color.
  • Create a column for duplicate records and fill it in.
  • Compare and contrast columns or sheets.

The steps to add an add-on to your Google Sheets document are as follows:

  • Open the Google Sheets document where the duplicates should be removed.
  • Go to the ‘Add-ons’ page.
  • In the menu, select the Add-ons option.
  • Select “Get Add-ons” from the drop-down menu.

Duplicate rows have been found and deleted

Since Google Sheets already has a built-in feature for efficiently removing duplicates, it’s best to use it if at all possible. The only time I’d consider using the add-on is if you need to do more than just remove duplicates.

  1. Delete Duplicates using the UNIQUE function

In Google Sheets, the UNIQUE feature returns unique rows from the given source set, discarding duplicates. The UNIQUE function returns rows in the source range in the order in which they first appear. You can access and compare both sets of data using this approach before removing the original duplicates.

  • This approach removes duplicates from the data set you to specify.
  • When the unique function tries to identify duplicates, it takes into account all of the columns in your data range. If you put it another way, a unique function compares each row of data and eliminates any duplicates (identical to others across the whole row).
  • It’s simple to use because it only needs one formula with one argument: the range you want to de-duplicate (remove duplicates from).
Delete Duplicates using the UNIQUE function
  • Here we have provided an example of how to use the UNIQUE feature. The feature is located in cell I1 and searches for duplicates in the A1:A15 data set.
  • The result is as follows:
UNIQUE function
  • Since the duplicate rows have been eliminated, the table on the right has fewer rows.
  1. Delete Duplicates in Google Sheets using Pivot Tables
  • For exploratory data processing, pivot tables are handy.
  • In Google Sheets, pivot tables are an excellent method for searching for duplicates. They’re incredibly scalable and quick to use, so they’re a perfect place to start if you’re unsure if your data has any copies.
  • Build a Pivot Table with your dataset highlighted (under the Data menu).
Delete Duplicates in Google Sheets using Pivot Tables
  • The Pivot Table editor appears in a new tab or same tab.
Create Pivot table in existing sheet
  • Select the column you want to look for duplicates under ROWS (e.g., program invoice number). Then, in VALUES, select another column (I usually use the same one) and make sure it’s set to COUNT or COUNTA (if your column contains text), as shown below:
  • Using a Pivot Table in Google Sheets, you can highlight duplicates.
  • Using a Pivot Table in Google Sheets, highlight duplicates.
  • Duplicate values will have a count greater than one, as you can see.

  • You can then look up the duplicate values in your original dataset and determine what to do next.
  • As you can see, this approach works well when you’re looking for duplicates and want to examine them further.

How To Remove Duplicates In Google Sheets. 

Creating a small script file that removes duplicate rows from your datasets is relatively easy. The benefit of writing an Apps Script program is that you can run it several times, such as adding new data. This software eliminates duplicates from Sheet 1’s dataset. It’s unique to the Sheet and data set, but it’s simple to build and alter.

  • In Google Docs, create a new spreadsheet or use an existing one with duplicates.
  • Add a few rows of data (for example, a list of contacts, parts inventory, etc.) and duplicate any of them if the spreadsheet is blank.
  • Select Script Editor from the Tools menu.
Script editor in tools
  • Now, search for any duplicate removing script on google or other known websites.
  • Copy the respective script to the script editor.
  • Click Run after selecting the feature, remove duplicates from the function dropdown list.
  • Take a look at the spreadsheet you’ve developed. There should no longer be any duplications.
