About Online Excel Viewer
Open a spreadsheet on any device without installing Excel. Switch between sheets, search across rows and export to XLSX or CSV.
How to use Online Excel Viewer
- Drop a spreadsheet file.
- Pick a sheet and use the filter box to search.
- Optionally download as XLSX or CSV.
Limitations
- Everything runs in your browser’s memory, so the practical file size depends on your device. As a rough guide: up to ~50 MB or ~500,000 rows works well on a modern laptop; phones and tablets handle much less.
- Very large files can make the tab slow or crash. If that happens, split the file first or use a desktop computer.
- Outputs keep values and formulas’ results but not formatting, charts, images, pivot tables or macros.
