Identifying and managing duplicates in a dataset is a crucial task in data analysis, and Google Sheets is a powerful tool that can help you achieve this. One of the most effective ways to do this is by highlighting duplicates in your sheet, which can save you a significant amount of time and effort. In this article, we will explore the steps to make Google Sheets highlight duplicates, making it easier to identify and manage duplicate data.
Why Highlight Duplicates in Google Sheets?
Highlighting duplicates in Google Sheets is essential for several reasons. Firstly, it helps you to quickly identify duplicate data, which can be a major issue in data analysis. Duplicate data can lead to inaccurate results, wasted time, and even errors in decision-making. Secondly, highlighting duplicates enables you to clean and remove duplicate data, which can improve the overall quality of your dataset. Finally, highlighting duplicates can also help you to identify patterns and trends in your data, which can be useful for making informed decisions.
How to Make Google Sheets Highlight Duplicates
In this section, we will provide a step-by-step guide on how to make Google Sheets highlight duplicates. We will cover the different methods and formulas you can use to highlight duplicates, including the use of conditional formatting and array formulas.
Method 1: Using Conditional Formatting
To highlight duplicates using conditional formatting, follow these steps:
- Select the range of cells that you want to check for duplicates.
- Go to the “Format” tab in the top menu.
- Click on “Conditional formatting” and select “Custom formula is.”
- In the formula bar, enter the following formula: =COUNTIF(A:A, A2)>1
- Click on the “Format” button and select the desired format.
- Click “OK” to apply the formatting.
This formula checks if the value in cell A2 is present more than once in the range A:A. If it is, the cell will be highlighted.
Method 2: Using Array Formula
To highlight duplicates using an array formula, follow these steps:
- Select the range of cells that you want to check for duplicates.
- Go to the “Formulas” tab in the top menu.
- Click on “Array formulas” and select “Array formula.”
- In the formula bar, enter the following formula: =ArrayFormula(IF(COUNTIF(A:A, A2)>1, “Duplicate”, “”))
- Press “Enter” to apply the formula.
- The formula will highlight the duplicates in the selected range.
This formula checks if the value in cell A2 is present more than once in the range A:A. If it is, the formula returns the text “Duplicate,” which is then highlighted.

How To Make Google Sheets Highlight Duplicates
In this article, we will explore how to use Google Sheets to highlight duplicates in a spreadsheet. This can be a useful tool for identifying and removing duplicate data, which can help to improve data quality and reduce errors.
Why Highlight Duplicates in Google Sheets?
Highlighting duplicates in Google Sheets can be useful for several reasons:
- Identify and remove duplicate data: By highlighting duplicates, you can easily identify and remove duplicate data from your spreadsheet, which can help to improve data quality and reduce errors.
- Improve data integrity: Highlighting duplicates can help to ensure that your data is accurate and consistent, which is important for making informed decisions.
- Save time: By identifying and removing duplicates, you can save time and effort in the long run by avoiding the need to manually review and correct duplicate data.
How to Highlight Duplicates in Google Sheets
To highlight duplicates in Google Sheets, you can use a combination of formulas and formatting. Here’s a step-by-step guide:
Step 1: Create a new column
To highlight duplicates, you’ll need to create a new column in your spreadsheet. This column will be used to display a message indicating whether a row is a duplicate or not.
Step 2: Use the COUNTIF formula
The COUNTIF formula is used to count the number of cells in a range that meet a specific condition. In this case, we’ll use the COUNTIF formula to count the number of cells in the range that match the value in the current cell.
Here’s the formula you’ll use:
COUNTIF(A:A, A2) > 1
This formula counts the number of cells in column A that match the value in cell A2. If the count is greater than 1, it means that the value is a duplicate.
Step 3: Use the IF statement (See Also: How To Merge Values In Google Sheets)
The IF statement is used to test whether a condition is true or false. In this case, we’ll use the IF statement to test whether the count is greater than 1. If it is, we’ll display a message indicating that the row is a duplicate.
Here’s the formula you’ll use:
IF(COUNTIF(A:A, A2) > 1, "Duplicate", "")
This formula tests whether the count is greater than 1. If it is, it displays the message “Duplicate”. If it’s not, it displays an empty string.
Step 4: Format the column
To make it easy to identify duplicates, you can format the column to display a different color or font style. You can do this by selecting the column and using the “Format” menu.
Example
Here’s an example of how to use the formulas and formatting to highlight duplicates in Google Sheets:
| Column A | Column B | Column C |
|---|---|---|
| John | Smith | NOT DUPLICATE |
| John | Doe | DUPLICATE |
| Jane | Smith | NOT DUPLICATE |
| Jane | Doe | DUPLICATE |
In this example, the column C displays a message indicating whether a row is a duplicate or not. The rows that are duplicates are highlighted in red.
Recap
In this article, we’ve learned how to use Google Sheets to highlight duplicates in a spreadsheet. We’ve used a combination of formulas and formatting to identify and display duplicates. By following these steps, you can easily identify and remove duplicate data from your spreadsheet, which can help to improve data quality and reduce errors.
Key Points:
- Create a new column to display a message indicating whether a row is a duplicate or not.
- Use the COUNTIF formula to count the number of cells in a range that match the value in the current cell.
- Use the IF statement to test whether the count is greater than 1 and display a message indicating that the row is a duplicate.
- Format the column to display a different color or font style to make it easy to identify duplicates.

Q: What is the purpose of highlighting duplicates in Google Sheets?
Q: How do I highlight duplicates in Google Sheets?
To highlight duplicates in Google Sheets, you can use the Conditional Formatting feature. Select the range of cells you want to check for duplicates, go to the Format tab, and select “Custom formula is” under the “Format cells if” dropdown menu. Then, enter the formula =COUNTIF(A:A, A1)>1 and apply the formatting.
Q: Can I highlight duplicates in multiple columns?
Yes, you can highlight duplicates in multiple columns by modifying the COUNTIF formula. For example, to highlight duplicates in columns A and B, enter the formula =COUNTIF(A:A, A1)+COUNTIF(B:B, B1)>1. This formula counts the number of occurrences of the value in both columns and highlights the cell if the count is greater than 1.
Q: How do I remove duplicates from a Google Sheet?
To remove duplicates from a Google Sheet, you can use the Remove duplicates feature. Select the range of cells you want to remove duplicates from, go to the Data tab, and select “Remove duplicates”. This will remove all duplicate values from the selected range, leaving only unique values.
Q: Can I highlight duplicates based on multiple criteria?
Yes, you can highlight duplicates based on multiple criteria by using the COUNTIFS formula. For example, to highlight duplicates in columns A and B where the value in column C is “USA”, enter the formula =COUNTIFS(A:A, A1, B:B, B1, C:C, “USA”)>1. This formula counts the number of occurrences of the value in columns A and B where the value in column C is “USA” and highlights the cell if the count is greater than 1.
