When the tree view wins

  • The document is large (≥ a few hundred lines) and the formatter scrolls forever.
  • You only care about a couple of nested fields and want to ignore the rest.
  • You’re reading a third-party API response and need to map its shape quickly.

Frequently asked questions.

How is this different from the formatter?
The formatter pretty-prints text. The tree viewer renders the parsed structure as collapsible nodes you can click open and closed. Better for huge documents where you want to drill down without scrolling.
How deep does the tree start expanded?
The first two levels are open by default. Click any chevron to toggle.
Is there a graph / visualizer view?
Yes — the "Graph" tab renders your JSON as an interactive node diagram you can pan, zoom, and click. Like a JSON visualizer, but it never uploads your data: the graph is built entirely in your browser.
Can I switch back to a raw view?
Yes — the "Raw" tab shows JSON.stringify with 2-space indent, in case you want to copy a section.
Does my JSON leave my browser?
No. Parsing and rendering happen client-side. There is no server.
