CSV Column Extractor pulls one column from pasted CSV data for quick cleanup, deduping, exports, and spreadsheet prep. It works locally in the browser.
Extract one CSV column by header name or zero-based column index. Everything runs locally in this tab.
Yes. The tool is free and runs directly in your browser with no account required.
No. The CSV is parsed locally in the browser tab and is not sent to a server.
Pulling a single column of values — like just the email addresses or just the IDs — out of a larger pasted CSV without opening a spreadsheet app.
Type either the exact header name from the first row (e.g. 'email') or a zero-based column index (e.g. '1' for the second column) into the selector field.
One value per line, taken from every row after the header, in the order they appear in the CSV.
It handles simple CSV well, but the parser splits on commas and strips surrounding quotes — a comma inside a quoted field may be misread as a column separator.
If the header name isn't found (and it isn't a valid numeric index), no matching column index is found, and the extracted values will be empty.
No — the tool extracts one column per run. For multiple columns, run the extraction again with a different header name or index and combine the outputs manually.
