Check quoting, consistent column counts, and a usable unique header, then report the detected delimiter and table size.
Inputs are limited to 1 MiB, 10,000 rows, and 256 columns.
Nothing is placed in a URL, account, or remote log.
Strict, bounded, local processing
A valid result means the text can be represented as one rectangular string-valued table; it does not validate domain-specific types or permissions.
The validator detects unclosed quotes, quotes placed inside unquoted fields, trailing characters after a closing quote, ragged rows, empty headers, and duplicate header names.
The report counts data rows separately from the header and identifies the delimiter selected by the parser.
CSV does not carry a universal type system. Dates, identifiers, enumerations, required values, and cross-row business rules still need a schema owned by the receiving system.
