Excel Viewer — View Excel Online
Open an Excel file (XLSX/XLS) or CSV and browse its sheets and rows directly in your browser, no Excel installation needed.
When to use it
Useful for a quick look at a file someone sent you, checking what sheets an Excel workbook has before processing it with another tool, or checking data on a computer without Excel installed (a Chromebook or a tablet, for example).
To work with the data (compare, merge, deduplicate, convert to JSON), use the data tools — this page is only for viewing.
Large files
If the file has many rows, only the first 200 are shown on screen to keep your browser fast — the full file is still loaded, only how much gets rendered at once is limited.
