Frequently Asked Questions
What is a tree view?
A tree view displays hierarchical data with expandable/collapsible nodes, making nested structures easy to explore.
Why use tree view instead of raw JSON?
Tree view makes complex JSON much easier to understand. You can expand only the parts you're interested in.
What are the color codes?
Colors distinguish data types: strings (green), numbers (blue), booleans (orange), null (gray).
Can I edit JSON in the tree view?
This viewer is read-only. Edit JSON in the input field and re-parse.
What about very large JSON?
Handles large JSON structures. Performance depends on your browser and complexity.
What if JSON is invalid?
Invalid JSON won't parse. Use the JSON Validator tool to check for errors first.
Can I expand all nodes at once?
This tool expands nodes individually. For large JSON, expand strategically.
How are arrays shown?
Arrays show index numbers [0], [1], etc. with item counts.
What about null and undefined?
JSON doesn't support undefined. Null values are shown as "null" in gray.
Is my JSON private?
Yes, all parsing happens in your browser. JSON never leaves your device.
