4. Enter the following formula: =countif($A$1:$A1,$A1)>1 (Replace ‘A’ with the column letter containing the data.)
5. Choose a formatting style to highlight the duplicates and click Done.

Now, all duplicate values in the selected range will be highlighted.

2. Using the Remove Duplicates Feature

Google Sheets also offers a built-in tool to remove duplicates. This feature not only identifies duplicates but also allows you to remove them, leaving only unique values. Here’s how:

1. Select the range of cells containing the data you want to analyze.
2. Click on Data in the top menu, then select Remove duplicates.
3. In the new window, ensure the correct range is selected and click Remove duplicates.

This action will remove all duplicate rows, leaving only the unique ones.

3. Using the Filter Feature

4. Using a Custom Formula

Google Sheets allows you to create custom formulas to find duplicates. This method is particularly useful for more complex data sets. Follow these steps:

1. In an empty column, enter the following formula in the first cell of the range: =if(countif($A$1:$A1,$A1)>1, "Duplicate", "Unique") (Replace ‘A’ with the column letter containing the data.)
2. Drag the fill handle (small square at the bottom-right corner of the cell) down to apply the formula to the entire range.

Now, each cell in the new column will display ‘Duplicate’ for any duplicate values and ‘Unique’ for any unique values.

Summary and Recap

In this article, we discussed four methods for finding all duplicates in Google Sheets:

• Using the conditional formatting feature to highlight duplicates
• Using the remove duplicates feature to eliminate duplicates
• Using the filter feature to isolate and manage duplicates
• Using a custom formula to identify and categorize duplicates

By mastering these techniques, you can efficiently manage your data, ensuring accuracy and saving time in your Google Sheets projects.
