About JSONPath Evaluator
Run JSONPath expressions against JSON data with filters, wildcards, recursive descent and match counts.
JSONPath Evaluator runs expressions against JSON documents and returns every match instantly, with a running count so you know whether a query hit one node or fifty. Filters such as price checks and status comparisons narrow the results, wildcards select whole arrays, and recursive descent scans nested objects several levels deep without rewriting the path by hand. The interface shows the source data, the expression and the matched values side by side, highlights syntax errors with a readable message and offers common snippets you can insert with a click. Backend developers use it while debugging API responses, analysts for cleaning exported payloads and students learning query syntax. JSONPath Evaluator is free, processes everything locally in your browser and never stores what you paste.

Frequently Asked Questions
Does the JSONPath Evaluator show how many nodes matched?
Yes. Alongside the extracted values it prints a match count, so you can tell immediately whether a wildcard selected the entire array or only a single object. If the expression is malformed, the evaluator points at the problem with a plain language message instead of returning an empty result, and you can adjust the filter and rerun it without reloading the page.
Is JSONPath Evaluator free to use?
Yes. JSONPath Evaluator is completely free with unlimited use — no account, download or payment required.
Is my data uploaded to a server?
No. JSONPath Evaluator runs entirely in your browser. Your inputs are never sent to our servers or stored anywhere.
Does JSONPath Evaluator work on mobile?
Yes. The interface is fully responsive and works in any modern browser on Android, iPhone, tablets and desktops.
