Question 1

What does this tool do?

Accepted Answer

This tool parses any JSON object or array and extracts every path to a leaf value, displayed in a table with the path (dot/bracket notation), the value (truncated if long), and the data type. It is useful for exploring unknown API responses or debugging JSON structures.

Question 2

What path notation is used?

Accepted Answer

Object keys use dot notation (e.g. user.address.city) and array indices use bracket notation (e.g. items[0].name). This matches the JSONPath convention used by most libraries.

Question 3

Can I filter the extracted paths?

Accepted Answer

Yes. The filter input at the top of the results table lets you search by path name or value. The table updates in real time as you type, making it easy to find specific fields in large JSON objects.

Question 4

How do I copy all paths?

Accepted Answer

Click 'Copy paths' to copy the full list of paths (filtered if a filter is active) as newline-separated text. This is useful for generating field lists for documentation or code generation.

Question 5

Is there a limit to the JSON size?

Accepted Answer

There is no hard limit, but very large JSON objects with thousands of keys may slow down the browser. The extraction runs entirely client-side with no data sent to any server.
