CSV Canonicalizer

A free browser-local utility for one carefully defined CSV subset. Text stays in this page’s memory for the current interaction: do not paste confidential data.

Accepts comma-delimited UTF-8 text up to 256 KiB, LF or CRLF record endings, and RFC-4180-style quoted fields. It refuses malformed input rather than repairing or guessing.

Paste CSV text, then canonicalize it locally.
