What is CSV Viewer/Editor?

The CSV Viewer/Editor displays your CSV and TSV files in a clean spreadsheet-style grid. Sort columns, edit cells inline, add or delete rows, and export your changes — all without installing any software.

How to use

1. Upload a CSV or TSV file by dragging it onto the drop zone, or paste raw CSV text directly into the editor.
2. Click any cell to edit it, use the column headers to sort, and right-click rows to insert or delete them.
3. When you're done editing, click Export to download the modified file as CSV, or copy the data to your clipboard.

Result

A data analyst uploads a 5,000-row customer export, corrects a misspelled company name in row 342, sorts by signup date, then re-exports the cleaned file — all in the browser.
