Frequently Asked Questions
How do I expand or collapse nodes?
Click the arrow next to any object or array to expand or collapse just that node, or use the Expand All / Collapse All buttons to control the whole tree at once.
Can I copy a value or its path?
Yes. Click the copy icon next to any node to copy its value, or the copy icon next to an object or array to copy its JSON path, such as $.user.name.
What happens if my JSON is invalid?
You'll see an error message with the line and column where the problem was found, so you can fix it before viewing the tree.
