How to Find Unique Values in Excel

When working with large amounts of data in Excel, it is often necessary to find unique values in a given range of cells. This can be useful for identifying distinct items in a list, removing duplicates, and ensuring that your data is accurate and reliable.

In this guide, we will show you how to find unique values in Excel using the built-in “Remove Duplicates” feature. This is a quick and easy way to identify and isolate unique values in a range of cells, making it a valuable tool for anyone working with data in Excel.

How to find unique values in Excel – formula examples

There are several formulas you can use to find unique values in Excel. Here are a few examples:

  1. =IF(COUNTIF(range, cell)=1, cell, ""): This formula will check if the number of times a particular value appears in the range is equal to 1. If it is, the formula will return the value, otherwise it will return an empty string.

Example: =IF(COUNTIF(A1:A10,A1) = 1,A1,””)

  1. =INDEX(range, MATCH(0, COUNTIF(range, range), 0)): This formula uses the INDEX, MATCH, and COUNTIF functions to find the unique values in a range. It works by counting the number of times each value appears in the range and returning the value that appears only once.

Example: =INDEX(A1:A10, MATCH(0, COUNTIF(A1:A10,A1:A10), 0))

  1. =IFERROR(INDEX(range, MATCH(0, COUNTIF(range, range)+(range<>""), 0)), ""): This formula is similar to the previous one but it will ignore the blank cells and any errors in the range, but it will not ignore the text values that look like numbers or dates.

Example: =IFERROR(INDEX(A1:A10, MATCH(0, COUNTIF(A1:A10,A1:A10)+(A1:A10<>””), 0)), “”)

  1. =IF(SUMPRODUCT(($A$1:$A$10=A1)*(ROW($A$1:$A$10)<ROW(A1)))=0,A1,""): This formula uses the SUMPRODUCT and ROW functions to find unique values in a range. It works by checking if a value in the range has already been found in a previous cell, and if not, it returns the value.

Example: =IF(SUMPRODUCT(($A$1:$A$10=A1)*(ROW($A$1:$A$10)<ROW(A1)))=0,A1,””)

Keep in mind that these formulas are just examples, and you will need to adjust them according to your specific needs by changing the range, cell and the way you want to filter the data.

Use Advance Filter in Excel :

Another way to find unique values in Excel is to use the “Advanced Filter” feature. Here’s how:

  1. Select the range of cells that you want to find unique values in.
  2. Go to the Data tab in the ribbon and click on “Advanced” in the Sort & Filter group.
  3. In the Advanced Filter dialog box, select “Unique records only” and choose a destination range for the unique values.
  4. Click “OK” to filter the range and display only the unique values in the destination range.

This method is useful when you want to filter unique values and copy it in another sheet or another range instead of removing the duplicate values.

Additionally, you can use a formula like =IF(COUNTIF(range, cell)=1, cell, "") in excel to find the unique values in a range. This formula will check if the number of times a particular value appears in the range is equal to 1. If it is, the formula will return the value, otherwise it will return an empty string.

Using Power Query Function :

Power Query is another way to find unique values in Excel. Power Query is an add-on for Excel that allows you to quickly and easily perform data transformations and clean up your data. Here’s how to use Power Query to find unique values:

  1. Click on the “Data” tab in the ribbon and select “From Table/Range”
  2. Select the range of cells that you want to find unique values in.
  3. In the Power Query Editor, go to the “Home” tab and select “Remove Rows” and then “Remove Duplicates”.
  4. Select the column you want to find unique values in and then click “OK” to remove the duplicates.
  5. Once the duplicates are removed, you can load the data back into your worksheet by clicking on “Close & Apply”

Power Query is a powerful tool that can be used to perform many different data transformations and clean-up tasks, including finding unique values. It’s particularly useful when working with large data sets and when you need to perform multiple data transformations.

Using UNIQUE Value Function :

The UNIQUE function is another way to find unique values in Excel. The UNIQUE function is a dynamic array function that returns a list of unique values from a given range of cells. Here’s how to use the UNIQUE function:

  1. Select the cell where you want the unique values to appear.
  2. Type =UNIQUE( and then select the range of cells that you want to find unique values in.
  3. Close the formula with a parentheses and press Enter.

The UNIQUE function will return an array of unique values in the selected range. However, you need to be aware that this function is not available in the older versions of Excel.

You can also use the UNIQUE function to return unique values from multiple ranges by including multiple ranges in the formula, separated by commas.

For example: =UNIQUE(A1:A10,B1:B10) will return a list of unique values from both ranges A1:A10 and B1:B10.

Also, the UNIQUE function will ignore the blank cells and any errors in the range, but it will not ignore the text values that look like numbers or dates.
