dev.csv-to-json

Convert CSV/TSV text to a JSON array. POST { csv, delimiter?, header? }. Auto-detects comma vs tab, handles quoted fields and escaped quotes, and coerces numbers/booleans/empty→null. With header=true (default) each row becomes an object keyed by the header row; header=false returns arrays.
