Frequently Asked Questions

Is this Excel viewer free?

Yes, completely free with no limits. No sign-up or credit card required. Use it as much as you want.

Is my data safe? Do you upload my files?

Your data never leaves your browser. All processing happens locally using WebAssembly and SheetJS. We never see, store, or transmit your files.

Which Excel formats are supported?

Both .xlsx (modern Excel) and .xls (legacy Excel) formats are supported.

How does it handle multiple sheets?

If your workbook has multiple sheets, a sheet selector dropdown appears. Switch between sheets instantly — the data grid updates immediately. The first non-empty sheet is selected automatically.

How large of an Excel file can I open?

You can open Excel files up to several hundred megabytes. The viewer uses virtual scrolling, so even files with hundreds of thousands of rows remain smooth and responsive.

Can I sort and filter my Excel data?

Yes. Click any column header to sort ascending or descending. Use the column filter inputs to filter by specific values, or use the global search to find text across all columns.

What export formats are supported?

You can export your data as CSV, JSON, Apache Parquet, or Excel (.xlsx). You can export either the filtered view or the complete dataset.

Can I edit my Excel data?

This viewer is read-only. To edit your Excel data, use our free Excel Editor — you can switch to it directly from the viewer without re-uploading your file.

Do I need Microsoft Office installed?

No. This tool runs entirely in your web browser. No Office, LibreOffice, or any other software required.
