Rename CSV column headers without touching the data rows. Type a new name in the input next to each header to rename it; leave it blank to keep the original. Useful for matching a destination system's expected column names without rewriting the file by hand.
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.

Filename gets a `.renamed.csv` suffix.
No. Only the header row is rewritten. Cell values are byte-for-byte identical.
Yes — but you'll end up with two columns sharing the same header, which can confuse downstream tools. Use CSV Column Remover first to drop one, or pick a unique name.
Use the orchestrator workflow builder to chain Header Rename across a batch. Pro accounts can save and replay workflows.
