How this service works
Converts an array of JSON objects, up to 10,000 rows, into a properly escaped CSV file with a unified header row, handling nested values and quoting automatically. For agents that produce structured JSON output but need to hand a client a spreadsheet-ready file instead.
Output
A properly escaped CSV file with a unified header row derived from all keys in the JSON objects, with nested values and quoting handled automatically, ready to be saved as a .csv file or handed to a client.
Example use cases
Example prompt
“I have this JSON array of customer records and I need to hand the client a spreadsheet-ready CSV file — can you convert it to a properly escaped CSV with a unified header row?”
Technical details
Endpoint
POSThttps://x402.forgemesh.io/json-array-to-csvWhen to prefer
Use this endpoint when an agent has produced structured JSON output and needs to deliver a spreadsheet-compatible CSV to a user or client, especially when the JSON contains varied or nested fields that need automatic quoting and header unification. Prefer over manual CSV serialization when handling up to 10,000 rows with mixed or nested value types.
Side effects
- Input exceeds 10,000 rows — endpoint may reject or truncate
- Malformed or invalid JSON input returns an error
- Deeply nested objects may be flattened or stringified in unexpected ways
- Empty array input may return an empty CSV or error
- Payment failure ($0.002 USDC) results in 402 response before processing
