XML to CSV API Documentation

Overview

The XML to CSV API converts well-formed XML data into a flattened CSV format.
It validates the XML structure, parses it safely, and outputs a downloadable CSV file.
This API supports synchronous conversion (direct body input) and asynchronous processing (remote file URL or uploaded file).

Notes for Developers

  • For large files or remote URLs, use asynchronous mode (x-source-type: url or x-source-type: file) to avoid timeouts.
  • The request_id is included in every response for tracking and debugging.
  • The preview field contains the first 100KB of the generated CSV for quick inspection.
  • The output file is stored securely and expires based on your plan’s retention policy.
  • Always verify the status_url for async jobs before downloading results.
  • Ensure that your input XML is well-formed and uses consistent tag structures for predictable CSV flattening.
