JSON Key Path Extractor

list unique object-key paths from nested JSON without including private scalar values.

Ready. Your working data stays in this browser.

Why this tool is useful

Use JSON Key Path Extractor when you need to list unique object-key paths from nested JSON without including private scalar values. The result is immediate and easy to verify before you reuse it.

How it works

Enter the values requested by JSON Key Path Extractor. The browser validates the input, performs the calculation locally and produces a copyable result with clear errors.

Practical example

A practical use is to run JSON Key Path Extractor on a small sample first, confirm the output, and then process the complete value or list.

Validation

The calculation is deterministic and explains validation errors instead of silently changing invalid input.

Privacy boundary

Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.

Result passport

Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
