Paste a single-line API response or a minified config file and click Format to beautify it into properly indented, readable JSON - choose 2-space or 4-space indentation depending on what your team's style expects. What was an unreadable wall of text becomes a document you can actually scan and understand at a glance.
Beautifying is a single, undoable action - your pasted text is left exactly as it arrived until you click Format, and Cmd+Z (or Ctrl+Z) instantly reverts to the original minified version if you need to paste it back somewhere else unchanged.
An optional key-sort mode alphabetizes object keys as part of beautifying, which is useful when comparing two JSON payloads that list the same keys in a different order - once sorted, the structural differences are much easier to spot by eye.
Because parsing and formatting both run in a background worker, beautifying a multi-megabyte log dump or API dump does not lock up the page - the beautified output appears in the raw pane and the tree at the same time, ready to read or copy.
