The #NUM error occurs in your Excel spreadsheet when a function or formula contains invalid numeric values. Remove #NUM errors this way!

When you see the #VALUE error, it means that there is something wrong with the way the formula is typed, or there is something wrong with the cells you are referencing.

The Excel file will get saved to your PC with a .xlsx extension, which can be opened in any spreadsheet app, including Microsoft Excel, Apple Numbers, OpenOffice, LibreOffice, and more.
