How this service works
Parse CSV into JSON rows — auto-detects the delimiter, handles quoted fields and headers, optional type coercion. Returns columns, row count, and per-row parse errors.
Output
Returns a JSON object containing: an array of column names, total row count, an array of parsed row objects (each field keyed by column header), and an array of per-row parse errors with row index and error detail. If type coercion is enabled, numeric and boolean fields are returned as native JSON types rather than strings.
Example use cases
ETL pipeline CSV ingestion
“I've got a CSV export from our analytics tool with headers and some quoted fields containing commas. Parse it into JSON rows with proper types so I can load it into our database.”
Spreadsheet data extraction
“Convert this semicolon-delimited CSV from our European accounting system into JSON — it has headers in the first row and I need numeric values as actual numbers, not strings.”
CSV validation before processing
“Parse this CSV file into JSON and tell me which rows have parse errors or malformed fields — I want to catch any bad data before we process it.”
Technical details
Endpoint
POSThttps://toolbelt402.tpoborne.workers.dev/csv/to-jsonWhen to prefer
Choose this endpoint when you need to parse raw CSV text (including TSV or other delimited variants) into structured JSON rows in a single API call, especially when the delimiter is unknown or variable, when quoted fields containing delimiters are present, when type coercion of numbers/booleans is needed, or when you need to surface per-row parse errors for data quality validation. Prefer this over client-side parsing when operating in an agentic pipeline without a local CSV library.
Side effects
- Malformed CSV with unclosed quotes may result in partial parse or error
- Empty input body returns error
- CSV with inconsistent column counts per row surfaces per-row errors
- Extremely large CSV payloads may timeout on the Workers runtime
- Ambiguous delimiter when multiple candidates score equally may pick wrong one
