Turn Minified JSON into Readable Code in One Click

July 4, 2026 · 3 min read

I opened a 500-line config file today and it was one single line of minified JSON — no indentation, no line breaks, nothing. Trying to find the one setting I needed to change was like reading a wall of text. I pasted it into Formly's JSON beautifier and it came back cleanly formatted with 2-space indentation. Thirty seconds to find the setting instead of thirty minutes of squinting.

Minified JSON saves bytes. Beautified JSON saves sanity. When you are debugging, editing, or reviewing JSON data, proper indentation is the difference between spotting the issue instantly and staring at a wall of characters for an hour. Beautify your JSON now →
