GhostSheet vs Excel Online / Google Sheets — Compared
Excel Online needs a Microsoft account; Google Sheets needs a Google account and uploads your file to Drive to open it. GhostSheet opens .xlsx, .csv, and .ods files right in your browser with no account and no upload — ideal for quickly viewing a spreadsheet someone emailed you without signing into anything.

- Opens .xlsx, .xls, .csv, and .ods; convert between formats
- No install, no extension — just open the file in a browser tab
