When working with large datasets in Google Sheets, it’s not uncommon to encounter duplicate values that can make data analysis and visualization more challenging. Extracting unique values is an essential step in data preprocessing, as it helps to remove redundancy, reduce data size, and improve data quality. In this tutorial, we will explore the different methods to extract unique values in Google Sheets, making it easier to work with your data and gain valuable insights.
Overview
This tutorial will cover three different approaches to extract unique values in Google Sheets:
Method 1: Using the UNIQUE Function
This method utilizes the built-in UNIQUE function in Google Sheets, which is a simple and efficient way to extract unique values from a dataset.
Method 2: Using the FILTER Function
This method employs the FILTER function to extract unique values by removing duplicates from a dataset.
Method 3: Using the Remove Duplicates Feature
This method uses the built-in Remove Duplicates feature in Google Sheets to extract unique values from a dataset.
By the end of this tutorial, you will be able to choose the best method for your specific use case and extract unique values in Google Sheets with ease.
How to Extract Unique Values in Google Sheets
Extracting unique values in Google Sheets is a common task that can be achieved using various methods. In this article, we will explore different ways to extract unique values in Google Sheets, including using formulas, functions, and add-ons.
Method 1: Using the UNIQUE Function
The UNIQUE function is a built-in function in Google Sheets that returns a list of unique values from a range or array. The syntax for the UNIQUE function is:
| UNIQUE(range) |
Where “range” is the range of cells that you want to extract unique values from. (See Also: How To Deploy App Script In Google Sheets)
For example, if you want to extract unique values from the range A1:A10, you can use the following formula:
| =UNIQUE(A1:A10) |
This formula will return a list of unique values from the range A1:A10.
Method 2: Using the FILTER Function
The FILTER function is another built-in function in Google Sheets that can be used to extract unique values. The syntax for the FILTER function is:
| FILTER(range, criteria) |
Where “range” is the range of cells that you want to extract unique values from, and “criteria” is the condition that you want to apply to the range.
For example, if you want to extract unique values from the range A1:A10, you can use the following formula:
| =FILTER(A1:A10, COUNTIF(A1:A10, A1:A10)=1) |
This formula will return a list of unique values from the range A1:A10.
Method 3: Using the Remove Duplicates Add-on
The Remove Duplicates add-on is a third-party add-on that can be used to extract unique values in Google Sheets. To use this add-on, follow these steps:
- Install the Remove Duplicates add-on from the Google Sheets add-on store.
- Select the range of cells that you want to extract unique values from.
- Go to the “Add-ons” menu and select “Remove Duplicates.”
- Click on “Remove duplicates” to extract unique values.
This add-on will remove duplicates from the selected range and return a list of unique values. (See Also: How To Convert Pdf Table To Google Sheets)
Method 4: Using a Script
You can also use a script to extract unique values in Google Sheets. To use a script, follow these steps:
- Open the Google Sheets script editor by going to “Tools” > “Script editor.”
- Paste the following script into the script editor:
| function getUniqueValues(range) { |
| var values = range.getValues(); |
| var uniqueValues = []; |
| for (var i = 0; i < values.length; i++) { |
| var value = values[i][0]; |
| if (uniqueValues.indexOf(value) == -1) { |
| uniqueValues.push(value); |
| } |
| } |
| return uniqueValues; |
| } |
- Save the script by clicking on the floppy disk icon or pressing “Ctrl+S” (or “Cmd+S” on a Mac).
- Go back to your Google Sheet and select the range of cells that you want to extract unique values from.
- Type “=getUniqueValues(A1:A10)” into a cell, replacing “A1:A10” with the range of cells that you want to extract unique values from.
- Press “Enter” to execute the script and extract unique values.
This script will return a list of unique values from the selected range.
Conclusion
In this article, we explored four different methods for extracting unique values in Google Sheets, including using the UNIQUE function, the FILTER function, the Remove Duplicates add-on, and a script. Each method has its own advantages and disadvantages, and the choice of method will depend on the specific needs of your project.
Remember to always test your formulas and functions before applying them to your data.
By following the steps outlined in this article, you should be able to extract unique values in Google Sheets with ease.
Summary of Key Points:
- The UNIQUE function is a built-in function in Google Sheets that returns a list of unique values from a range or array.
- The FILTER function can be used to extract unique values by applying a condition to the range.
- The Remove Duplicates add-on is a third-party add-on that can be used to extract unique values.
- A script can be used to extract unique values using a custom function.

Frequently Asked Questions: How to Extract Unique Values in Google Sheets
How do I extract unique values from a single column in Google Sheets?
To extract unique values from a single column, you can use the UNIQUE function. Simply enter the formula =UNIQUE(A:A) in a new column, where A:A is the range of cells containing the data you want to extract unique values from. This will return a list of unique values in the column.
Can I extract unique values from multiple columns in Google Sheets?
Yes, you can extract unique values from multiple columns using the UNIQUE function in combination with the TRANSPOSE function. For example, if you want to extract unique values from columns A and B, you can use the formula =UNIQUE(TRANSPOSE(A:B)). This will return a list of unique combinations of values from both columns.
How do I ignore blank cells when extracting unique values in Google Sheets?
To ignore blank cells when extracting unique values, you can use the FILTER function in combination with the UNIQUE function. For example, if you want to extract unique values from column A and ignore blank cells, you can use the formula =UNIQUE(FILTER(A:A, NOT(ISBLANK(A:A)))). This will return a list of unique values, excluding blank cells.
Can I use the UNIQUE function to extract unique values from a range of cells that includes headers?
Yes, you can use the UNIQUE function to extract unique values from a range of cells that includes headers. However, you’ll need to adjust the formula to exclude the header row. For example, if your data is in the range A1:B100 and you want to extract unique values from column A, excluding the header row, you can use the formula =UNIQUE(A2:A100). This will return a list of unique values, excluding the header.
How do I extract unique values and count the frequency of each value in Google Sheets?
To extract unique values and count the frequency of each value, you can use the UNIQUE function in combination with the COUNTIF function. For example, if you want to extract unique values from column A and count the frequency of each value, you can use the formula =QUERY(QUERY(A:A, “SELECT A, COUNT(A) GROUP BY A”), “SELECT Col1”). This will return a list of unique values and their corresponding frequencies.
