工作原理

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.
