When working with data in Excel, counting unique values can often be a crucial part of data analysis. Unique values help provide insights into your data sets, allowing for a better understanding of trends and occurrences. Whether you’re analyzing survey results, inventory lists, or any dataset where duplicates may occur, knowing how to effectively count unique values will save you time and provide clearer insights. Here are five tips to help you count unique values in Excel effectively.
Tip 1: Use the Remove Duplicates Feature
One of the quickest ways to count unique values in a dataset is to use the Remove Duplicates feature. This process will alter your original data, so it's recommended to make a copy first!
Steps to Remove Duplicates:
- Select the range of cells that contains the values you want to evaluate.
- Go to the Data tab in the ribbon.
- Click on Remove Duplicates.
- Choose which columns to check for duplicates if you’re working with multiple columns.
- Click OK.
After this, Excel will let you know how many duplicates were removed and how many unique values remain. You can easily see the unique count in the remaining data.

Tip 2: Utilize the COUNTIF Function
Another practical way to count unique values is by using the COUNTIF function. This function allows you to count the occurrences of each value and helps you identify unique items by leveraging an array formula.
Example:
If your data is in the range A1:A10, you can use the following formula:
=SUM(1/COUNTIF(A1:A10, A1:A10))
Steps:
- Select a cell where you want to display the unique count.
- Enter the formula above.
- Instead of just pressing Enter, press Ctrl + Shift + Enter to make it an array formula.
Excel will then show you the count of unique values in the selected range.

Tip 3: Use the UNIQUE Function (Excel 365 and later)
If you’re using Excel 365 or later, you have access to the UNIQUE function, which can simplify counting unique values significantly.
Example:
To get a list of unique values from a range A1:A10, use:
=UNIQUE(A1:A10)
Steps:
- Select a new cell for the output.
- Type the formula.
- Press Enter.
This will output an array of unique values, and you can then count them using the COUNTA function:
=COUNTA(UNIQUE(A1:A10))
This provides both the unique values and their count directly.

Tip 4: PivotTable for Unique Counts
PivotTables are a powerful tool in Excel for summarizing data, including counting unique values. They can quickly provide a count of unique items in a dataset.
Steps to Create a PivotTable:
- Select your dataset.
- Go to the Insert tab and click on PivotTable.
- Choose where you want the PivotTable report to be placed (new worksheet or existing).
- In the PivotTable Field List, drag the desired field to the Rows area.
- Drag the same field to the Values area. This will default to a count.
- Click on the field in the Values area, select Value Field Settings, and change to Distinct Count.
This will give you the unique count of the selected field in your PivotTable.

Tip 5: Advanced Filter
Using the Advanced Filter feature in Excel allows you to extract unique values into a new range without altering your original data.
Steps to Apply Advanced Filter:
- Select your data range.
- Go to the Data tab and click on Advanced in the Sort & Filter group.
- Choose Copy to another location.
- Specify the List range and Copy to location.
- Check Unique records only and click OK.
This will copy the unique values to your specified location, allowing you to easily count them afterwards.
<p class="pro-note">📝 Pro Tip: After using Advanced Filter, remember that you can simply count the values in the new location for easy reference!</p>
