Why was my filter rejected?

Filters that run an expression are disabled so a path cannot execute code. Use a direct selector.

What does an empty list mean?

The document parsed and the path matched nothing. That is a successful result.

No. The path runs in your browser.

Paste JSON and a path. No match is an empty list, not an error.

Filter scripts such as [?(@.ok)] are rejected. The path is not evaluated as code.

Ctrl+Enter or ⌘+Enter runs this tool immediately.

JSONPath

JSON document

Matches

Waiting for input.

Parsing stays in this browser. Input is not uploaded or saved.

Paste a JSON document, or load the sample.
Type a JSONPath such as $.owners[0].name. The matches appear after you pause typing.
A path that selects nothing returns [] and the status says there was no match.

The path uses JSONPath field, index, slice, and wildcard selectors.
Script expressions, including [?(@.field)] and [(expr)], are rejected and produce no output.
Invalid JSON produces no matches.
No match is a successful empty list. It is not reported as a parse error.
The document is not rewritten.

$.owners[0].name selects one string.

$.owners[0].name

$.missing matches nothing. The result is an empty list.

$.missing

Eval prevented: Remove the script filter. Use a name or an index instead.
Invalid JSON: Fix the document before testing the path. A bad document does not produce matches.
Invalid JSONPath: Check brackets and dots. The status quotes the parser message.

JSON Schema validator
Check a JSON document against a JSON Schema in the browser. Draft-07 and 2020-12 are supported, and remote $ref values are not fetched.
JSON formatter
Validate JSON, then pretty-print it with 2 or 4 spaces or minify it. Invalid JSON produces an error and leaves the output empty.
JSON to YAML converter
Convert valid JSON into YAML with 2-space or 4-space indentation. Nested objects, arrays, and multiline strings are preserved, and invalid JSON is reported instead of repaired.
