Frequently Asked Questions
- Does it handle quoted fields with commas?
- Yes. The parser follows RFC-4180: double-quoted fields can contain commas, newlines, and escaped quotes.
- Which directions are supported?
- Any combination of CSV, TSV, and JSON - six directions total. The first row is treated as headers for JSON output.
- What about columns with inconsistent counts?
- Rows with fewer fields than the header are padded; extra fields are kept. A warning appears if the shapes differ.
