When working with large datasets in Google Sheets, it’s not uncommon to encounter duplicates in your data. This can be particularly problematic when creating pivot tables, as duplicates can skew your data and make it difficult to draw accurate conclusions. In this article, we’ll explore the importance of removing duplicates in pivot tables and provide a step-by-step guide on how to do so in Google Sheets.
Why Remove Duplicates in Pivot Tables?
Removing duplicates in pivot tables is crucial for several reasons:
- Pivot tables are designed to summarize data, and duplicates can lead to inaccurate summaries.
- Duplicates can also make it difficult to identify trends and patterns in your data.
- Removing duplicates can help to reduce data redundancy and improve data quality.
In Google Sheets, duplicates can occur due to various reasons such as:
- Multiple entries with the same values in the same column.
- Entries with the same values in different columns.
- Entries with the same values in multiple rows.

Alternative Methods to Remove Duplicates
If you don’t want to use the Remove duplicates feature in Google Sheets, there are alternative methods to remove duplicates in pivot tables. Here are a few:
Method 1: Using the UNIQUE Function
You can use the UNIQUE function to remove duplicates in pivot tables. Here’s an example:
| Column A | Column B |
|---|---|
| John | Smith |
| John | Jones |
| Jane | Doe |
To remove duplicates using the UNIQUE function, follow these steps:
- Select the cell range that contains the data you want to analyze.
- Type the following formula in the formula bar:
=UNIQUE(A:A). - Press Enter to apply the formula.
Method 2: Using the QUERY Function
You can also use the QUERY function to remove duplicates in pivot tables. Here’s an example: (See Also: How to Add a Divider in Google Sheets? Easy Steps)

| Jane | Doe |
To remove duplicates using the QUERY function, follow these steps:
- Select the cell range that contains the data you want to analyze.
- Type the following formula in the formula bar:
=QUERY(A:A, "SELECT DISTINCT A"). - Press Enter to apply the formula.
Conclusion
Removing duplicates in pivot tables is an important step in data analysis. In this article, we’ve explored the importance of removing duplicates and provided a step-by-step guide on how to do so in Google Sheets. We’ve also discussed alternative methods to remove duplicates using the UNIQUE and QUERY functions. By following these steps, you can ensure that your pivot tables are accurate and free of duplicates.
FAQs
Q: What is the difference between the Remove duplicates feature and the UNIQUE function?
A: The Remove duplicates feature is a built-in feature in Google Sheets that allows you to remove duplicates in a pivot table. The UNIQUE function is a formula that can be used to remove duplicates in a pivot table. While both methods can be used to remove duplicates, the Remove duplicates feature is more user-friendly and easier to use.
Q: Can I use the Remove duplicates feature on a pivot table that is not a summary table?
A: No, the Remove duplicates feature can only be used on a pivot table that is a summary table. If you try to use the feature on a pivot table that is not a summary table, you will receive an error message.
Q: How do I know if I have removed all the duplicates in my pivot table?
A: To check if you have removed all the duplicates in your pivot table, you can use the Review duplicates feature in the Remove duplicates dialog box. This feature will allow you to review the results of the duplicate removal process and ensure that all duplicates have been removed.
Q: Can I use the UNIQUE function to remove duplicates in a pivot table that is not a summary table?
A: Yes, you can use the UNIQUE function to remove duplicates in a pivot table that is not a summary table. However, you will need to use the QUERY function in combination with the UNIQUE function to achieve this. For example, you can use the following formula: =QUERY(A:A, "SELECT DISTINCT A").
Q: Is it possible to remove duplicates in a pivot table that is not a summary table using the QUERY function?
A: Yes, it is possible to remove duplicates in a pivot table that is not a summary table using the QUERY function. You can use the following formula: =QUERY(A:A, "SELECT DISTINCT A"). This formula will remove duplicates in the pivot table and return a new table that contains only the unique values.
