Markdown table → CSV API

Extract the first GFM table to CSV/TSV.

POST /api/v1/convert/table-to-csv extracts the first GFM pipe table from a markdown document and returns RFC-4180 CSV (or TSV). Round-trips with /api/v1/convert/csv-to-table.

Overview

Finds the first GFM pipe table in the document and emits CSV or TSV. Cells that contain the delimiter, quotes, or newlines are escaped per RFC 4180.
