Frequently asked questions
Why use a tree view instead of formatting?
A collapsible, colour-coded tree lets you explore deeply nested JSON and focus on the branches you care about — easier than scrolling raw text.
Can it handle large JSON?
Yes, though extremely large documents may render slowly since everything runs in the browser.
Is my JSON private?
Yes — it's parsed and displayed locally, never uploaded.
