JSON Path Finder — Find JSONPath by Key or Value

What is JSON Path Finder?

A JSON path finder does the opposite of a JSONPath tester. Instead of running a JSONPath expression against JSON and getting matching values, you supply the key or value substring and get back the JSONPath (and dot-path) for every occurrence. It's the fastest way to answer questions like 'where is the author field in this deeply nested API response?' or 'which paths in this config file mention `staging`?'. This tool walks the entire tree once and returns every match with its full path, node type, and a truncated value preview so you can click the right one immediately.

How to find JSONPath from a key or value

1. 1Paste your JSON into the input editor on the left.
2. 2Type a key substring, a value substring, or both. Results update as you type.
3. 3Toggle 'Exact key' / 'Exact value' if substring matching is producing too many hits.
4. 4Click the copy icon on any result row to copy the JSONPath to your clipboard.

Tips & Best Practices

• ▸Use both key and value filters together to precisely locate a specific field: key = 'author', value = 'Tolkien'.
• ▸For non-identifier keys (with dashes, spaces, or dots), the tool automatically switches to bracket notation ($['field-name']) in the JSONPath output so the expression parses correctly in downstream tools.
• ▸Results are capped at 500 matches. If you hit the cap, narrow the query — running an unfiltered search on large payloads isn't useful anyway.
