json_to_csv

Pack: csv · Connect: https://pipeworx.io/mcp (see Connect below for a single-pack URL)

No MCP client? Call it directly: GET https://gateway.pipeworx.io/v1/tools/json_to_csv for the schema, then POST the same URL with its arguments for the data.

Serialize an array of JSON objects (or arrays) to CSV (keyless, offline). Object keys become the header (union of all keys, in first-seen order). Fields are quoted when needed.
