Is my spreadsheet uploaded?

No. The file is read locally with the File API and parsed in your browser.

Which delimiters are supported?

Comma, semicolon, tab and pipe — pick the one matching your file from the delimiter selector.

Does it handle quoted values with commas?

Yes, the parser follows RFC 4180 rules including escaped double quotes and newlines inside quoted fields.

Can I export to JSON?

Yes. With a header row, each row becomes an object keyed by the column names.

How big a file can I open?

Tables are shown 200 rows per page, so files with tens of thousands of rows stay responsive; the limit is your device memory.

Can I undo a mistake?

Yes. Every edit, sort, transform and delete can be undone and redone (last 50 steps).

Can I export only some rows?

Yes. Type in the search box and the export contains only the matching rows.
