How this service works

Convert a JSON array of objects to CSV format. Supports custom delimiters. Pure algorithmic — instant and cheap.

Example use cases

Example prompt

“Convert this JSON array to CSV using a semicolon as the delimiter: [{"name":"Alice","age":30,"city":"Paris"},{"name":"Bob","age":25,"city":"Lyon"}]”

Endpoint

GEThttps://api.strale.io/x402/json-to-csv

When to prefer

Choose this endpoint when you need a pure, instant, cheap algorithmic conversion of a JSON array of objects to CSV with no external dependencies. Ideal for preparing API response data for spreadsheet download, data pipeline output, or human-readable tabular exports. Prefer this over general-purpose code-execution endpoints when the task is purely JSON-to-CSV formatting.

Side effects

Input array is empty — may return empty CSV or error
Array elements have inconsistent keys — missing fields may produce blank columns
Invalid JSON passed in data param — returns parse error
Non-array value passed as data — schema validation error
Unsupported delimiter characters may cause malformed CSV output
