Format, convert, and navigate JSON as a tree.

JSON Studio is a proper home for messy JSON - pretty-print it, validate it, sort the keys, convert between JSON and YAML, and walk the whole thing as a collapsible tree where you can copy any value or its exact path with a click.

What JSON Studio covers.

Concrete features, inputs, and workflow details for this tool.

From blob to readable

Paste a wall of JSON and get it formatted, validated, and key-sorted, so a noisy API response becomes something you can scan.

Walk the tree

Expand and collapse nested structures and copy any node's value or its exact JSONPath, instead of counting brackets by hand.

JSON and YAML, both ways

Flip a config between JSON and YAML in a click when the next tool wants the other one.
