Free JSON Path Finder

The JSON Path Finder is a free online tool that lets you explore JSON data structures visually and find the exact path to any value.

Yes, it is completely free with no registration required. All processing happens client-side in your browser.

The JSON Path Finder displays JSON as an interactive tree, letting you click on any value to see its full path notation for use in code.

Yes, the JSON Path Finder is fully responsive and works on smartphones and tablets. You can use it on any device with a modern web browser -- no app download required.

No account or registration is needed. Simply open the JSON Path Finder in your browser and start using it immediately. There are no sign-up walls or usage restrictions.

Simply enter your input in the provided field, adjust any settings to your preference, and the tool will process it instantly. You can then copy the result to your clipboard or download it.

The JSON Path Finder works in all modern browsers including Chrome, Firefox, Safari, Edge, and Opera. For the best experience, use the latest version of your preferred browser.

Both describe how to reach a value in JSON, just with different syntax. Dot notation chains keys with periods, like data.user.name, and is the compact form most JavaScript code uses. Bracket notation wraps each key in quotes and brackets, like data["user"]["name"], which is safer when a key contains spaces, dashes, dots, or other characters that would break dot access. The two are interchangeable for plain keys, so data.user and data["user"] point to the same value. For array elements you always use brackets with the index, such as items[0]. This tool lets you select any node in the tree and copies its path in dot notation, bracket notation, JSONPath, or Python form, so you can paste the exact syntax your language expects without rewriting it by hand.

JSONPath is a query language for JSON, similar in spirit to what XPath is for XML. A path starts with the root symbol $ and walks down the structure, so $.store.book[0].title reads the title of the first book. Beyond simple lookups it supports wildcards like $.store.book[*].author to return every author in an array, recursive descent with $..price to find a key at any depth, filters like $.store.book[?(@.price < 10)] to keep only matching items, and array slices and unions such as [0:3] for a range or [0,2] for specific indices. The Query tab here evaluates these expressions live against your pasted JSON and lists every match, making it a fast scratchpad for testing an expression before you drop it into code or automated tests.

Use recursive descent, written as two dots in a JSONPath expression. The pattern $..price matches a key named price wherever it appears, whether it sits at the top level, inside a nested object, or deep within an array of arrays, and returns all of those values at once. This saves you from manually expanding every branch to hunt for a field, which is tedious in large API responses or config files where the same key repeats across many records. Paste your JSON into the Query tab, type the recursive expression, and the tool lists each match along with where it was found. If you only need the location once, you can also use the search box to filter the tree by key, path, or value and narrow results to a single value type before copying the path you want.

Flattening turns a deeply nested object into a single flat map where each entry is a full path paired with its value, for example user.address.city mapped to its string. This is what you need when a destination expects flat keys rather than a tree, such as a CSV column layout, environment variables, or a tool that cannot read nested structures. The Flatten tab does this in one step and lets you choose the separator between path segments, so you can match the convention your target system uses. It can also reverse the process, rebuilding a nested object from flat path-to-value pairs, which is handy when you are importing data back from a spreadsheet. Everything runs locally in your browser, so even large payloads convert instantly without an upload. Paste your JSON and open the Flatten tab to try it.

Open the Diff tab, paste one document on each side, and the tool compares them by path. It reports which paths exist only in the first document, which exist only in the second, and which appear in both, so you can immediately see fields that were added, removed, or are shared between the two versions. This is far quicker than scanning two payloads side by side and counting brackets, and it is especially useful for spotting what changed between two API responses, two config revisions, or a request and its expected fixture in a test. Because the comparison is path-based, it works even when keys are reordered, which a plain text diff would flag as noise. As with the rest of the tool, both documents are parsed locally and never leave your device. Paste your two JSON files into the Diff tab to see the differences.
