JSON Key Extractor
Paste a JSON object to list its keys and nested paths, including keys inside array objects.
Example
For {"user":{"name":"Ada"}}, the output includes user and user.name. Arrays use [] in their paths, such as roles[].title.
What to know
This tool lists structure, not values. Array entries with the same object keys produce one unique path. Invalid JSON is rejected with the browser's parser error.

Questions
Does it upload my JSON?
No. Parsing runs in the browser on this page.
Can it extract values too?
No. Use JSON Formatter to inspect values.
