Spreadsheets, no account

Open Excel files without Excel.

View, search, edit and convert .xlsx, .csv, .ods and more — parsed on your device, never uploaded to a cloud.

GhostSheet opens and converts spreadsheets in your browser — no Excel, no Google account, no upload. View and edit .xlsx, .xls, .csv, .ods and .tsv files as a clean sortable table, search across every cell, fix values inline, and export to CSV, Excel (.xlsx) or JSON. The file is parsed on your device, so a financial model or a customer list is never sent to a server just to be read.

Questions, answered

Can I open an .xlsx file without Excel?

Yes. GhostSheet renders Excel files as a clean table in your browser — no Microsoft Office and no Google account needed.

Does the spreadsheet get uploaded?

No. The file is parsed entirely on your device, so sensitive data (finances, contacts) is never sent to a server.

How do I convert XLSX to CSV or JSON?

Open the file and use the export menu to download it as CSV, Excel or JSON — the conversion runs locally.

Can I edit cells before exporting?

Yes. Click any cell to change its value, then export the corrected file.

What formats can I open?

.xlsx, .xls, .csv, .ods and .tsv. You can also paste tabular data directly.

Everything runs in your browser. Your files are never uploaded — for the single-file tools there's no upload endpoint to send them to.
