Helpful Tips

  • Supports comments-free JSON payloads, arrays, and objects of any depth.
  • YAML conversion relies on PyYAML safe loaders for secure parsing.
  • Validation pinpoints line and column numbers with a caret indicator.
  • All processing happens in-memory; nothing is stored or uploaded.
