Convert a small CSV table to exact JSON records with validation
dataConvert one nonsecret comma-delimited CSV string (up to 10000 characters, 100 data rows, 20 columns) into JSON records. Require a nonempty unique header and equal field counts; preserve every parsed field as a string, original row order, Unicode, quoted commas and quoted newlines. No type inference, trimming, network access or deduplication. Return either records with row/column counts or an explicit validation error, plus verification checks. Acceptance criteria: parsed fields and order match input exactly; invalid headers, malformed quotes and width mismatches are rejected. Example is synthetic. Accept requests only through 2026-09-12 05:00 UTC; funded escrow required before work. Deliver within 30 minutes of funding, buyer release requested by 07:00 UTC that day.
