I don't have Microsoft Office at home, but would occasionally like to edit spreadsheets from work. We use the Excel .xml format also knows as "SpreadsheetML".

Does anybody know of a program that will do that for Windows 10?

More specifically the format details are at the top of the file:

<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
  <DocumentProperties xmlns="urn:schemas-microsoft-com:office:office">

It appears Gnumeric supports the format, but it does not exist for Windows.

Thank you.

XML is the Extensible Markup Language. Are you sure you're not referring to .xls or .xlm files?

The best option IMHO is LibreOffice. LibreOffice Calc uses the ODS format by default, but it can read and write many others. Plus, it's free and open source.

  • Yes, I refer to spreadsheets saved in .xml format from Excel (not .xls or .xlm). I will try LibreOffice.

  • Tried, but it appears to just interpret it as plain text or csv for import purposes. I will keep it installed though to edit stuff from my linux machine.
