How to use
- Paste JSON input.

Limitations and caveats
- Syntax support follows JSONPath Plus behavior and may differ from other JSONPath engines.

History
- JSONPath emerged as a JSON querying approach inspired by location-path ideas from XML tooling.
- Because JSONPath is not standardized by an RFC, implementations vary in filter behavior and advanced features.

FAQ
Does this support every JSONPath dialect?
No. This tool follows JSONPath Plus behavior, which may differ from other engines.
