About the JSON Formatter
The JSON Formatter makes messy JSON readable and checks that it is valid. Paste your JSON, then beautify it with neat indentation or minify it to a single compact line.
If your JSON has a syntax error, the tool points it out so you can fix it fast. Your data is processed entirely in the browser and never uploaded.
Beautify re-indents with 2 spaces, 4 spaces or a tab; Minify strips every bit of whitespace to one compact line for APIs or config files. For example {"a":1,"b":[2,3]} beautifies to a neatly indented block and minifies straight back to that single line.
