Strip non-allowed characters from a CSV. Choose which character classes to keep (letters, digits, spaces, punctuation) and the tool removes everything else from every cell. Useful for normalising messy free-text fields before importing into systems with strict character requirements.
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.

Not directly today — keeping all four classes will remove only emojis (since they don't fall in any of the four), but it'll also remove other non-ASCII characters. Use CSV Find & Replace with a regex like `[\u{1F300}-\u{1FAFF}]` for emoji-only stripping.
