Frequently Asked Questions
What's the difference from JSON Formatter?
JSON Formatter beautifies JSON for reading. JSON Viewer provides an interactive tree structure to explore nested data, search, and copy specific paths or values.
Can I collapse all nodes?
By default, the first two levels are expanded. You can manually collapse nodes by clicking them. Re-parsing will reset the expansion state.
What does the path copy do?
It copies the JSON path to that node (e.g., 'root.users[0].name'). This is useful for accessing data programmatically or referencing specific values.
Is my JSON data stored anywhere?
No, all parsing and tree rendering happens entirely in your browser. Your JSON never leaves your device.
