How to Highlight Duplicates in Google Sheets

Highlighting duplicates in Google Sheets can be helpful when working with large datasets to quickly identify and clean up any redundant or erroneous information. Here are the steps to highlight duplicates in Google Sheets:

  1. Open the Google Sheet containing the data you want to check for duplicates.
  2. Select the range of cells where you want to check for duplicates.
  3. Click on “Format” in the top menu bar, and then select “Conditional formatting” from the dropdown menu.
  4. In the Conditional format rules pane that opens on the right, select “Custom formula is” under the “Format cells if” dropdown menu.
  5. In the “Value or formula” box, type the formula “=countif(range,cell)>1”, replacing “range” with the range of cells you selected in step 2 and “cell” with the active cell in that range.
  6. Select the formatting style you want to apply to duplicate cells. This could be a specific fill color or font style that helps them stand out.
  7. Click “Done” to apply the conditional formatting rules to your selected range.

Once you have set up the conditional formatting rules, any duplicate values in the selected range will be highlighted according to the formatting style you chose in step 6. You can easily modify or remove the formatting by going back to the “Conditional formatting” pane and adjusting the rules as needed.

In conclusion, highlighting duplicates in Google Sheets is a useful way to quickly identify and clean up redundant data in large datasets. By following the steps outlined above, you can easily set up conditional formatting rules to highlight duplicates in your Google Sheet and keep your data organized and error-free.
