Microsoft Excel comes with a lot of built-in functionality that doesn't restrict you to comparing data in two columns using only one method.

If you are unfamiliar with inputting formulas into Microsoft Excel, the much simpler way to get the number of unique values in an Excel column is through a filter.

Creating a list of duplicate values that’s separate from the data source is easier than ever thanks to Microsoft Excel's FILTER() function.

You can split cells into columns in Excel using the "Text to Columns" tool, which is a great way to organize lots of data.

If you want duplicate values to stand out in an Excel spreadsheet, you can choose between two conditional formatting rules.
