How to use JSON Path Query

Extract specific data using paths such as $.users[*].name or $["unusual key"]. Only property access and array selection are supported; no expression or JavaScript evaluation occurs.

  1. Paste JSON and a path beginning with $.
  2. Select Run tool to extract matching values into an array.
  3. Review the result, then copy it or download the generated file.

Good to know

  • Up to 100,000 input characters, 10,000 values, and 40 nesting levels. Standard JSON numbers use JavaScript precision; duplicate keys retain their last value.
  • Supports .key, ["key"], [0], and array [*] only; no filters, recursive descent, scripts, slices, or full JSONPath standard compliance. Paths are limited to 500 characters.

Common questions

What happens if a property is missing?

That branch produces no match. A completely missing path returns an empty array.
