About json tree viewer
Explore JSON as a collapsible tree. Expand and collapse sections to understand large responses.
Useful for
- Finding a nested value in a big API response.
- Understanding the shape of unfamiliar data.
- Copying the path to a field.
A worked example
A 5,000-line API response is collapsed to its top-level keys. Expand data, then items, then the first item to see its fields. The viewer shows types, counts and the path of the selected node, such as data.items[0].price.
Tips
- Use search to find a key quickly.
- Copy the path to use it in code or in a query.
- Check for unexpected nulls and empty arrays.
Large files
Very large JSON can slow a browser tab. For multi-megabyte files, open only the sections you need or use a command-line tool such as jq.
Sensitive data
Responses often contain tokens and personal data. Remove them before sharing a screenshot of the tree with others.
