When is a tree view useful?
With large, deeply nested API responses, finding a field is much faster than in formatted text: collapse the branches you don't care about and open only what you need.
How do I get the path of a field?
Click any node in the tree; its path appears in the bar above as $.user.roles[0] and can be copied in one click.
Is my data safe?
Yes. The JSON is parsed and rendered in your browser and is never sent to any server.
