How this service works
Convert CSV string to JSON array with auto-detected delimiter and type inference. Algorithmic.
Output
Returns a JSON array of objects where each row becomes a JSON object with keys from the header row (if present), and values automatically cast to their inferred types (numbers, booleans, strings, etc.)
Example use cases
Example prompt
“Convert this CSV string to a JSON array — it has a header row and I'm not sure if the delimiter is a comma or semicolon: 'name;age;city\nAlice;30;New York\nBob;25;London'”
Technical details
Endpoint
GEThttps://api.strale.io/x402/csv-to-json?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a raw CSV string (not a file URL) and need a structured JSON array back without having to specify the delimiter yourself — especially useful for CSVs of unknown origin where the separator (comma, semicolon, tab, pipe) isn't guaranteed. It also saves a step by inferring numeric and boolean types automatically rather than returning all values as strings.
Side effects
- Malformed or empty csv_string returns an error
- Ambiguous delimiter that cannot be auto-detected may cause incorrect parsing
- CSV with inconsistent column counts per row may produce unexpected output
- Missing required csv_string query parameter returns a 400-level error
- Very large CSV strings may hit size or timeout limits
