Excel Viewer — Open and View XLSX & XLS Files Online

Open and view Excel spreadsheets right in your browser with this free online Excel viewer. Drop in an .xlsx or .xls workbook and instantly see its rows and columns rendered as a clean, scrollable HTML table — no Microsoft Excel, Google Sheets account, or software install required. Multi-sheet workbooks get a sheet picker so you can jump between tabs, and the first row is shown as a header. Because everything runs 100% in your browser, your file is never uploaded to a server and your data stays completely private.

🔒 100% private — files never leave your device

Frequently asked questions

What file formats does the Excel viewer support?

It opens modern .xlsx workbooks and legacy .xls files. Just select one file and its sheets are rendered as tables in your browser.

Are my files uploaded to a server?

No. The viewer runs 100% in your browser and reads the workbook locally on your device. Your spreadsheet is never uploaded, so your data stays completely private.

Can I edit or download the spreadsheet here?

No — this is a view-only tool for reading spreadsheets. It renders the rows and columns as a table but does not edit cells or export a file.

Can I view a workbook with multiple sheets?

Yes. If your workbook has more than one sheet, a dropdown appears so you can switch between sheets and view each one as its own table.

Do I need Microsoft Excel or an account?

No. You do not need Excel, Google Sheets, or any account or install. The viewer works in any modern browser, and it is completely free.

Is there a file size limit?

There is no fixed limit, but because the file is processed in your browser's memory, very large workbooks with many rows may load more slowly on lower-powered devices.
