Cách hoạt động

Received an .xlsx or .ods file and don't want to upload it to Google Sheets or buy Excel just to peek inside? This opens spreadsheets directly in your browser.

1
The spreadsheet engine loads
A current build of the SheetJS library is fetched from its official CDN the first time you open a file, then cached by your browser.
2
You pick a spreadsheet
Your file is read into memory locally — XLSX, XLS, CSV, and ODS are all supported. Nothing is uploaded.
3
Sheets are rendered as tables
Each worksheet is parsed and displayed in a scrollable grid with column letters and row numbers; switch between sheet tabs freely.
4
Export if you need to
Convert the active sheet to CSV or JSON with one click — handy for feeding data into other tools.

Spreadsheets often hold sensitive data — finances, contacts, salaries. Here the file is parsed entirely on your device, so you can safely inspect a file from an untrusted source without it leaving your computer.
