#FAQ
How is this different from a JSON formatter? ▾
A JSON formatter outputs formatted text. The tree viewer provides an interactive, collapsible tree where you can expand and collapse nodes to explore large JSON structures without scrolling through thousands of lines.
Can I view large JSON files? ▾
Yes, the tree viewer is optimized for large JSON structures. Nodes start collapsed so you can navigate to the data you need without rendering the entire document at once.
