Paste or upload CSV, auto-detect the delimiter and edit it as a table with row and column operations, undo, and standards-compliant CSV and JSON export.
FAQ
Which delimiters are supported? Is there a size limit?
Comma, tab, semicolon and pipe are supported with auto-detection. Tables are capped at 500 rows x 50 columns; content beyond 100KB is not saved to browser storage.
Will the exported CSV open correctly in Excel?
Yes. Export follows the CSV standard and quotes cells containing commas, quotes or line breaks automatically. The same table can also be exported as JSON.
