System Requirements
Mark's Spreadsheet requires Microsoft Excel 2010 or newer or Microsoft Excel 365 (desktop version) on a PC or Mac with macros enabled. Mark's Spreadsheet requires Excel macros for its powerful optimization functions - other spreadsheet programs (e.g. Google Sheets, Numbers, Open Office, LibreOffice) and Microsoft 365 for the web) will not work.
Some IT departments may disable the ability to use the macro feature of Microsoft Excel on work computers.
