How to use it
Paste your JSON and click View Tree. Click any object or array to expand or collapse it. Use Expand All / Collapse All to control the whole tree at once.
Frequently Asked Questions
Does this work for very large JSON files?
It works well into the tens of thousands of nodes since collapsed branches aren't rendered until expanded. Extremely large files (tens of MB) may still be slow to parse.
Can I copy a single value from the tree?
Select the text of any leaf value directly — the tree is built from real text, not an image or canvas, so browser text selection and copy work normally.
