About this tool
Paste JSON and enter a JSONPath expression to inspect matches across objects, arrays, wildcards, and recursive paths.
Common JSONPath syntax
Use property, array index, wildcard, and recursive path queries such as $.users[*].name, with formatted JSON results.
A safer workflow for large JSON
Normal input runs after a short debounce. Larger documents pause automatic execution so you can choose when to run the query.
How to use this tool
- Paste JSON and enter an expression such as $.users[*].name.
- Wait for the debounced result, or select Run for large input.
- Review the matches, format the input, or copy the result.
Private, local processing
Your JSON and JSONPath expression are processed only in this browser. They are not sent to NexaForge servers or analytics.
Frequently asked questions
Will JSONPath Tester upload my JSON?
No. JSON parsing, JSONPath evaluation, formatting, and copying all happen locally in your browser.
What happens when there are no matches?
The tool shows No values matched this JSONPath. as an empty state, not an error.
Can I use large JSON documents?
