DEDICATED TOOL PAGE

Extract selected columns from CSV data.

Paste CSV text, choose the columns you want to keep, and return a smaller CSV output. This is useful for quick cleanup before sharing, debugging or importing data elsewhere.

DEVELOPER TOOL

Run the tool

Enter column numbers like 1,3 to keep only the first and third columns. Quoted fields are supported.

WHEN IT HELPS

Structured cleanup without opening a spreadsheet.

Keep only what you need

Large exports are often hard to review because they carry too many fields. Column extraction creates a smaller working set fast.

Good before sharing examples

You can reduce a CSV to only the explanatory columns before posting it in docs, tickets or product discussions.

Helpful for debugging imports

When an import fails, it is often easier to inspect a reduced version of the CSV before changing the whole file.

Common questions

Does this support quoted fields?

Yes. The parser supports common quoted CSV values, including commas inside quoted cells.

Why use this instead of a spreadsheet?

It is faster for quick reductions when the job is simply “keep columns 1 and 3” rather than full spreadsheet editing.
