Excel Viewer
Open .xlsx, .xls, .ods, and .csv spreadsheets in your browser — multi-sheet tabs, column letters, and copy-friendly cells. Files never leave your device. Free, private, runs in your browser.
Upload limit: 30 MB. Sheets larger than 1,000 rows × 60 cols are clipped to keep the page fast — full data is still in the CSV download.
