Overview
Choose an .xlsx or .xls file to see its contents rendered as a readable table, without opening Excel or Google Sheets. Multiple sheets in the same workbook are supported - switch between them with the tabs above the table. The file is parsed entirely client-side using SheetJS's spreadsheet-parsing library; nothing is uploaded anywhere, which matters when the spreadsheet you're checking contains real data you'd rather not hand to a random upload-based converter site.
Best for: Quickly checking what's in a spreadsheet without opening Excel
