JSON Path Finder
Find and extract values from JSON using JSONPath
About the JSON Path Finder
Large JSON responses bury the one value you actually want under layers of nesting. JSON Path Finder lets you write a path expression and pulls that value straight out, so you do not have to scroll and count brackets.
It is built for the everyday case of "I just need users[0].address.city out of this 400-line response." API developers use it to confirm where a field lives before writing code that reads it; testers use it to extract a single value to assert against. Quick-select buttons give you a starting point, and you refine the path from there.
The supported syntax is the practical core of JSONPath: the root token, dot notation for nested keys, and bracket notation for array indices — enough to reach any specific value in a typical document.
How to Use the JSON Path Finder
- Paste your JSON into the "JSON Input" box.
- Type a path in the expression field — start from $ and use dot notation for keys and [n] for array indices, e.g. $.users[0].email.
- Use a quick-select button as a starting point if you want, then refine the expression.
- Click Find to extract the value at that path.
- Read the result (formatted as JSON) and Copy it; if the path does not exist, an error tells you where it failed.
Why Use ToolForge’s JSON Path Finder
- It evaluates real path expressions — root, nested keys, and array indices — so you extract exactly one value instead of eyeballing a huge document.
- When a path does not resolve, it names the segment that failed, which helps you correct a typo or a wrong assumption about the structure.
- Results come back as formatted JSON with a copy button, ready to paste into a test or a request.
- Parsing and lookup run entirely in your browser, keeping response data private.
Frequently Asked Questions
What path syntax does this support?
It supports the common core of JSONPath: $ for the root, dot notation for object keys (such as $.user.name), and bracket notation for array indices (such as $.items[0]). You can combine them, like $.data.items[2].id, to reach a deeply nested value.
Does it support wildcards or filters?
No. Advanced JSONPath features such as wildcards (selecting every element of an array) and filter expressions are not supported here — the tool resolves a single, concrete path to one value. For selecting many matching items, use a JSON filtering tool.
Why do I get "path not found"?
The expression points to a key or index that does not exist in your JSON — often a misspelled key, the wrong array index, or a level of nesting that is not there. The error names the segment it could not resolve so you can adjust the path.
