- Read the formatted result, then copy or download it.
About the JSONPath Tester
The JSONPath Tester runs a JSONPath expression against your JSON and shows the matched values live. It runs as plain JavaScript inside the page, which means there is no upload step, no queue and no size limit imposed by a server — the only limit is your own device.
What people use it for
- Working out the right selector before writing code.
- Extracting one field from a large response.
- Debugging an automation step that reads JSON.
Frequently asked questions
Is the JSONPath Tester free?
Free, unlimited, and no email address required. You can use it a hundred times a day and nothing changes.
Is what I paste into the JSONPath Tester stored?
No. The JSONPath Tester runs entirely in your browser using JavaScript. Because the work happens locally, the utility also keeps working if your connection drops, and closing the tab is all it takes to discard everything.
Who is the JSONPath Tester for?
The jobs it is built for: working out the right selector before writing code. Extracting one field from a large response. Debugging an automation step that reads JSON. It is built for exactly those cases rather than being a general-purpose tool with this bolted on.
Will this work on a tablet?
Yes. The page is responsive and the utility works in Chrome, Safari, Firefox, Edge and Samsung Internet on both Android and iOS. There is no app to install and nothing to sign into.
