About XLSX Viewer
Excel workbooks are a hassle to open when you don’t have Excel installed, and uploading a spreadsheet full of figures to a random site is the last thing you want. This viewer parses the workbook locally and lays each sheet out as a table with tabs, showing formula results as the file stored them. It reads .xlsx, older .xls, and OpenDocument .ods.
