Frequently Asked Questions
Can it parse both objects and arrays?
Yes. The extractor handles nested objects and array paths with [] notation.
What happens with invalid JSON?
You will see an explicit parse error and no paths are generated until syntax is fixed.
Is output deduplicated?
Yes. Repeated paths are deduplicated and sorted for easier reading.
