Delimiter: Pad ragged rows to header width Trim whitespace around fields Drop fully-empty rows

What gets repaired

Byte-order mark (BOM) at the start of the file is stripped.
Mixed line endings (CRLF, LF, CR) are normalized to CRLF.
Unbalanced quotes are recovered on a best-effort basis instead of crashing the parser.
Ragged rows are padded (or truncated) to the header width.
Fields containing the delimiter, quotes, or newlines are properly quoted on output.
Fully-empty rows are dropped.

Nothing is uploaded. Open the network tab — you'll see no outbound requests when you repair.
