Strip unwanted columns from a CSV before sharing or importing. Useful for removing PII (phone, SSN, internal IDs), test-only fields, or columns the destination system doesn't accept. All processing happens in your browser.
Free is enough for most one-off jobs. Pro raises the file and batch caps; Pro + Media unlocks GB-scale streaming and unlimited duration.
Larger files supported on Developer (5 GB CSV) and Enterprise (unlimited). All processing happens in your browser — files never reach a server.

Both are shown separately in the checklist (by index). You can keep one and drop the other.
