How To Count Unique Values In Excel
Have a data with duplicates.
Select the range of cells, or have it all in a table.
Click on Data Tab (1), and choose Advanced (2) in Sort & Filter.
Click copy to another location (1), where you want to copy it to (2), check on the unique records only (3), and click ok.
List Range: =&A&1:&A&14
Note: If the cells you choose in number 2 isn’t large enough to contain all the unique numbers, Excel would automatically enlarge it.
As you can see there is a possible that data in your tables or reports will be duplicated. To extract only distinct/unique data like products/employee/companies/cities etc. just use this trick.
You can also count distinct values in pivot table.
