How to Use the JSON Path Value Extractor
When you're staring at a deeply nested API response or config file and just need one value, this tool gets straight to it. Paste your JSON, then enter a path like user.address[0].city using dots for keys and square brackets for array indexes, and only the value at that location is extracted. If the result is an object or array, it's shown neatly formatted, and the value's type (string, number, boolean, object, array, or null) is displayed alongside it.
Useful for
- Quickly checking a specific field in a complex API response
- Looking up a single option inside a config.json file
- Finding an item buried in nested arrays or objects
- Confirming a value before digging through the full JSON structure while debugging
Frequently Asked Questions
What format should the path be in?
Separate keys with a dot and use square brackets for array indexes, e.g. user.address[0].city
What happens if I enter invalid JSON?
An error message appears so you can fix the syntax and try again.
What if the path doesn't exist?
A message tells you no value was found at that path — check for typos or a key that doesn't exist.
