This tool follows the JSONPath standard (RFC 9535) and passes its official test suite. Script expressions like (@.length-1) and =~ from older tools aren't part of the standard: the error message shows the standard way.

Frequently asked questions

      
What is JSONPath?
A short way to pick values out of JSON, like $.store.book[0].title. $ is the whole document, a dot or [ ] goes into a field or a list, and .. searches at every depth. Many APIs, databases and tools such as kubectl and Postman use it.
How do I filter items in JSONPath?
Use ? with a test, where @ is the current item: $..book[?@.price < 10] gives the books cheaper than 10. Combine tests with && and ||, and use ! for not.
Which JSONPath syntax does this tool use?
The official standard, RFC 9535, and it passes the standard's compliance test suite. That includes filters, slices, the functions length(), count(), match(), search() and value(), and normalized paths.
Why doesn't my expression from another tool work?
Older tools had extras like (@.length-1), =~ or in that aren't in the standard. The error message shows the standard way, for example [-1] for the last item or match() for a regular expression.
How do I get the path of each match?
Under Show, choose Paths, or Paths and values. Paths can be normalized ($['store']['book'][0]) or in dot style ($.store.book[0]).
Is my JSON uploaded?
No. Everything runs in your browser, so you can safely test API responses, configuration files and private data. Large numbers keep every digit.
