How to Highlight Duplicates in Google Sheets

Using Conditional Formatting

To highlight duplicates in Google Sheets, start by leveraging the powerful conditional formatting feature. With this feature, you can easily identify duplicate data in your spreadsheet. The key is to use the COUNTIF function in a custom formula within the conditional formatting settings.

Steps to Highlight Duplicates in a Column

First, open your spreadsheet in Google Sheets. Next, highlight the column where you want to check for duplicates. Click on "Format" in the top menu, then select "Conditional Formatting." In the "Format cells if" dropdown menu, choose "Custom formula is" and enter the formula =COUNTIF(A:A, A1) >1. Click "Done" to apply the formatting and see the highlighted duplicates.

Highlighting Duplicates Across Multiple Columns

To highlight duplicates across multiple columns, adjust your formula accordingly. For example, use =COUNTIF(B:B, B1) >1 to check duplicates in column B. Use the $ symbol in your formula to specify exact cells. This method ensures that Google Sheets accurately highlights the duplicates across your desired columns.

Highlighting Duplicates in Entire Rows

You can also use conditional formatting to highlight duplicates in entire rows. Create a custom formula such as =AND(COUNTIF(ArrayFormula($I$3:$I$165&$J$3:$J$165),$I3&$J3)>1,$I3<>"") for this purpose. This formula will check for duplicates across a range of columns and highlight the entire rows with duplicate values.

Finding Duplicates in Different Sheets

Conditional formatting can also be used to highlight duplicates across different sheets in Google Sheets. Use a formula like =COUNTIF(Sheet1!A:A, Sheet2!A1)>1 to identify duplicates between Sheet1 and Sheet2. This method allows you to manage data consistency across multiple sheets effectively.

Extra Tips

To highlight the second instance of a duplicate instead of the first, use the formula =COUNTIF($B4:$B$5500,B)>1. This helps in identifying repetitions after the first occurrence, making it easier to clean up your data. Whether you are working with single columns, multiple columns, rows, or even different sheets, Google Sheets provides robust tools to highlight duplicates and maintain data integrity.
