FAQ
▶What is JSONPath?
JSONPath is a query language for JSON. It helps you select and extract values from JSON documents using path-like expressions.
▶How do I filter arrays in JSONPath?
Use filter expressions like $.items[?(@.price < 10)] to select array elements by conditions.
▶Why does my JSONPath return empty results?
Common reasons include invalid JSON input, a typo in keys, mismatched array/object structure, or using a JSONPath syntax not supported by your library.
▶Does this tool support recursive descent?
Yes. Use .. to search for keys at any depth, for example $..author.
