Method 1: Using the Built-in Function
Google Sheets provides a built-in function to identify duplicates. You can use the UNIQUE function to remove duplicates and then use the INDEX and MATCH functions to find the duplicates.
Here’s an example:
| Column A | Column B |
|---|---|
| John | Smith |
| John | Jones |
| Mary | Johnson |
| John | Smith |
To find the duplicates, follow these steps:
- Enter the following formula in a new column:
=UNIQUE(A:A) - Press Enter to apply the formula
- Enter the following formula in another new column:
=INDEX(A:A,MATCH(A2,A:A,0)) - Press Enter to apply the formula
This will highlight the duplicate values in Column A.
Method 2: Using Conditional Formatting
Another way to spot duplicates is by using conditional formatting. You can use a custom formula to highlight the duplicate values.
Here’s an example:
| Column A | Column B |
|---|---|
| John | Smith |
| John | Jones |
| Mary | Johnson |
| John | Smith |
To use conditional formatting, follow these steps:
- Select the range of cells you want to check for duplicates
- Go to the Format tab and click on Conditional formatting
- Choose Custom formula and enter the following formula:
=COUNTIF(A:A,A2)>1 - Press Enter to apply the formula
This will highlight the duplicate values in Column A. (See Also: How To Automatically Adjust Columns In Google Sheets)
