How to use CSV Column Extractor

Paste CSV, choose whether the first row contains headers, then supply an exact header name or one-based column number. The chosen cells appear as a JSON string array.

Example

From `name,city` followed by `Ana,Rabat`, selecting header `city` returns `["Rabat"]`.

What to know

CSV column results are JSON arrays rather than newline-separated cells so multiline values and commas are preserved. Headers match exactly; ragged rows that lack a selected column are rejected.
