About this tool
Format makes the JSON readable with the indent you choose. Minify removes all whitespace, which is useful before you paste a payload into a request or a test. Sort keys orders object keys alphabetically at every level, which makes two payloads easier to compare.
Shortcut: Ctrl + Enter formats the input.
