How do I view an Excel file without Microsoft Office?

Open a browser-based Excel viewer. Drop your .xlsx or .xls file. The viewer renders all sheets, columns, and data in your browser — you can switch between sheets, sort columns, and search. No Microsoft Office, no Google account, no software installation. The file stays on your device.

Can I edit the Excel file in the viewer?

The viewer is read-only — it displays your spreadsheet data but does not support editing. For editing, use Google Sheets (free with a Google account) or LibreOffice Calc (free desktop software). The browser viewer is for quick viewing when you just need to check data without installing anything.

Does the viewer support formulas?

The viewer displays the calculated values in formula cells, not the formulas themselves. It renders the spreadsheet as it would appear in Excel. Complex formatting, charts, and pivot tables may not render perfectly — the viewer handles standard data, text, numbers, and basic formatting well.

Is my spreadsheet uploaded to a server?

No. The viewer processes the file entirely in your browser. Your spreadsheet data never leaves your device. This matters for sensitive data — financial reports, employee lists, customer data — where uploading to Google Sheets or other cloud services creates data privacy considerations.

What Excel file formats are supported?

.xlsx (modern Excel format, Excel 2007+) and .xls (legacy Excel format, Excel 97-2003). Both are fully supported. The viewer also handles multi-sheet workbooks — you can switch between sheets using tabs.

Can I view Excel files on my phone?

Yes. The browser viewer works on mobile browsers. Upload the file from your phone, and the spreadsheet renders with horizontal scrolling for wide data. For better mobile viewing, convert the Excel file to CSV or HTML using the converter tools.
