Frequently Asked Questions (JSON Viewer)

What is an Interactive JSON Viewer?

An Interactive JSON Viewer parses raw JSON and displays it as a collapsible, nested tree structure. This makes it far easier to read and inspect huge nested payloads like API responses and configurations compared to viewing raw lines of code.

How do I filter keys or values in the tree?

Simply type your keyword in the search bar above the tree viewer. The tool will highlight matching keys or values and outline the nodes containing the query.

Does this viewer support folding?

Yes. You can click on the arrow icons next to any object or array node in the tree to collapse or expand it. You can also click the global Expand/Collapse All buttons to reset the tree state.
