How to open an XLSX file without Excel
- Drop the .xlsx or .xls file.
- Keep PDF to read it, or choose CSV or ODS to edit it in Google Sheets, Numbers or LibreOffice.
- Click Convert and open the result.
An XLSX file is a Microsoft Excel workbook (Office 2007 and later). You can open it with Excel, but also for free with LibreOffice Calc, Apple Numbers, Google Sheets (upload it to Drive) or Excel Online with a Microsoft account. When you only need to read it, the quickest way is a PDF: every sheet is printed as a table you can open on a phone, a tablet or any computer, without installing anything.
If you want to edit the data, convert to CSV to load it into any program, or to ODS for LibreOffice. Formulas are calculated and kept as values in CSV and PDF; the ODS and XLSX outputs keep the formulas. Several files can be converted at once, up to 50 of 300 MB.
Files are processed in memory on the server and deleted after 30 minutes; nothing is published or shared. If the file asks for a password when you open it, remove it first with Unlock Excel file, then convert it here.
