How do I read this API response without a formatter site?
A raw JSON response in a browser tab is one long line, and the usual next step is pasting it into a formatter site - which is a stranger’s server receiving whatever was in it. This opens the same body in a window of its own as a folded tree you can search, with a lint pass over it, and nothing crosses the network.

What this actually is
pretty-print, tree and diff any json on the pageOn any endpoint you have opened in a tab, and as a scratch editor for a payload from somewhere else. The window is separate from the panel because a nested response is not readable in a 340px column.
Asked about this tool
4 of themWhat happens on a page that is not JSON?
It opens as an empty editor, so it is still the fastest way to read a payload you have on your clipboard. It never guesses at half-JSON inside an HTML document.
Is anything sent to be formatted?
No. The parse, the tree and the search all run in the window. That is the whole argument for having it here rather than using a site.
Why is it a separate window rather than a panel tab?
Because a nested response is thousands of lines wide and a 340px column is not where one is read. The switcher gets you between it and the other windows without going back to the panel.
Does it re-read when I switch tabs?
It reads when it opens, from the tab it was opened on. A viewer that silently re-read on focus would show you a body from a page you had navigated away from.
how to use json
- Open the endpoint in a tab, then open JSON - it reads that tab's body.
- The tree opens in a window of its own, because a nested response is unreadable in a 340px column.
- Search by substring to find the key. Hits are marked in place.
- Read the lint pass for duplicate keys, suspicious numbers and tokens.
