Frequently asked questions

What does it extract?

Every key in the document along with its full path and the value stored there, including nested objects and arrays.

Why extract keys?

To understand the shape of large or unfamiliar JSON, build schemas, or find where a particular field lives.

Are duplicate keys shown?

Keys that repeat under different paths are each listed with their own unique path so nothing is hidden.
