How to Highlight Duplicates in Google Sheets

tutorial how to highlight duplicates in google sheets

To highlight duplicate values in Google Sheets is actually a little difficult. A duplicate value in Google Sheets refers to a situation where the same data or value appears more than once in a particular column or range of cells. This can be a problem if you are trying to organize your data or perform calculations on it, as it can cause confusion or lead to inaccurate results.

One way to avoid or fix duplicate values in Google Sheets is to use the Remove Duplicates feature. This tool allows you to select a range of cells, and it will automatically identify and remove any duplicate values within that range. This can save you a lot of time and effort compared to manually identifying and deleting duplicate values.

Another way to prevent duplicate values in Google Sheets is to use data validation rules. This feature allows you to set conditions for the values that can be entered into a specific range of cells. For example, you could set a rule that only allows unique values to be entered, which would prevent any duplicate values from being added to the sheet.

In general, it is important to keep an eye out for duplicate values in your Google Sheets data and take steps to prevent or fix them, as they can cause problems and hinder your ability to accurately analyze and use your data.

In addition, if we already have a lot of data in Google Sheets we can find duplicate/duplicate data by highlighting it with the color we want such as red, yellow, blue, green and so on. Here’s a guide on how to highlight duplicate values in Google Sheets.

The “$” sign here is very important, you will not be able to check for duplicate values in random cells if you don’t use the “$” sign. The formula “>1” itself has the meaning that if the data is found more than one.
