How to Highlight Duplicates in Google Sheets

There are a few ways to highlight duplicates in Google Sheets. One way is to use the built-in "Find and Replace" function. Another way is to use a custom function or script.

To highlight duplicates using the "Find and Replace" function, first select all of the cells that you want to check for duplicates. Then go to the "Tools" menu and select "Find and Replace." In the "Find" field, type in "=duplicate()" without the quotes. This will find all of the cells that have duplicates in them. In the "Replace" field, type in "=highlight()" without the quotes. This will highlight the duplicates in yellow. Click on "Replace All" and the duplicates will be highlighted in yellow.

To highlight duplicates using a custom function or script, first select all of the cells that you want to check for duplicates. Then go to the "Tools" menu and select "Script Editor." This will open a new script editor window. In the script editor window, paste the following code into the editor:

function highlightDuplicateCells() {

var range = document.getSelection().getRange();

var duplicates = range.duplicate();

range.setBackgroundColor("yellow");

}

This code will highlight the duplicates in yellow. To run the code, go to the "Run" menu and select "Run Function." The duplicates will be highlighted in yellow.
