JSON Path Finder
Navigate nested JSON data with path expressions. Supports dot notation, bracket notation, and array indexing with instant results and path listing.
What is a JSON path finder?
A JSON path finder is a tool that helps you navigate through nested JSON data structures using path expressions. It allows you to locate, extract, and view specific values buried deep within complex JSON objects without manually traversing each level.
What JSON path notations are supported?
This tool supports dot notation (e.g., data.user.name), bracket notation (e.g., data["user"]["name"]), and array indexing (e.g., data.items[0]). You can mix notations freely in a single path expression.
How do I access array elements?
Use square brackets with the index number, e.g., items[0] for the first element, items[2] for the third. Array indices start at 0. Negative indices are not supported.
What happens if the path does not exist?
The tool will display "undefined" or "Path not found" to indicate that the specified path does not exist in the JSON data. The result type badge will show "undefined".
Can I use wildcards in the path?
Currently, wildcards are not supported. You need to specify the exact path. For example, use items[0].name instead of items[*].name.
How does the List Paths feature work?
Click the "List Paths" button to automatically scan your JSON data and display all available paths as clickable chips. Click any chip to auto-fill the path input and instantly see the value at that path.
Is my JSON data sent to a server?
No, all processing happens entirely in your browser. Your JSON data is never transmitted to any server, making it safe to use with sensitive or confidential data.
What is the maximum JSON size supported?
There is no hard limit, but performance depends on your browser's memory. The tool handles typical API responses and configuration files efficiently. Very large files (hundreds of MB) may slow down.
What result types are shown?
The tool identifies and displays the type of the result value: string, number, boolean, object, array, null, or undefined. Each type has a distinct color badge for quick identification.
Can I copy the extracted value?
Yes, click the "Copy" button next to the result to copy the value to your clipboard. Objects and arrays are copied as formatted JSON strings.
Do I need to install any software?
No, this is a completely web-based tool that runs in your browser. No installation, registration, or dependencies required. Just paste your JSON and start finding paths.
What are common use cases for this tool?
Common uses include: debugging API responses, extracting specific fields from large JSON files, learning JSON path syntax, validating data structures, and generating path expressions for code that processes JSON data.
