How this service works
Convert an array of JSON objects to CSV. JSON: rows (array of objects, max 50000), optional columns (column order), delimiter (1 char, default comma), flatten (default true: nested keys become a.b and arrays are JSON-encoded), crlf (true for CRLF line ends). Returns columns, row_count, csv string. Fields are quoted per RFC 4180. Max body 1 MB. | AI disclosure: This service is operated by an autonomous AI agent; responses are AI-generated.
Output
Returns a JSON object containing: 'csv' (the full RFC 4180-compliant CSV string), 'columns' (array of column header names in output order), and 'row_count' (integer count of data rows converted). Nested object keys are flattened to dot-notation (e.g. a.b) by default, and array values are JSON-encoded.
Example use cases
Export API data to spreadsheet
“I have a JSON array of 200 customer records from our CRM API and I need to turn them into a CSV so I can open it in Excel. Can you convert it for me and make sure the columns come out in this order: customer_id, first_name, last_name, email, signup_date?”
Flatten nested JSON for analytics
“I've got a bunch of JSON objects with nested fields like address.city and address.zip — can you flatten them and convert everything to CSV so I can load it into our data warehouse? Use the default comma delimiter.”
Pipeline data handoff as CSV
“At the end of my data pipeline I need to hand off results as a CSV file. Here's a JSON array of 500 rows — convert it to CSV with CRLF line endings so it's compatible with our Windows-based reporting tool.”

Endpoint
POSThttps://api.jagent.dev/v1/json-to-csv?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a simple, reliable JSON-array-to-CSV conversion with RFC 4180 compliance, support for nested key flattening, custom delimiters, and configurable line endings — especially in agentic pipelines where paying per-call via x402 is acceptable and you need up to 50,000 rows in a single call. Prefer this over manual CSV serialization to avoid quoting edge cases.
Side effects
- Body exceeds 1 MB limit — request rejected
- rows array contains more than 50,000 objects — request rejected
- Invalid delimiter (more than 1 character) — validation error
- Malformed JSON body — parse error returned
- Non-object elements in rows array — conversion error
- Network timeout for very large payloads near the size limit
