FAQ

Questions LLM JSON Extractor owners ask.

  • 01

    How does the extraction work?

    The server uses a scan-based approach with a counter to track opening and closing braces and brackets, ensuring nested structures are fully captured.

  • 02

    Can it handle markdown code blocks?

    Yes, the get_extraction_metadata capability can specifically identify if the detected JSON is wrapped in markdown code blocks.

  • 03

    What happens if the JSON is invalid?

    The verify_json_integrity capability will return a failure status and a human-readable reason explaining why the syntax is incorrect.
