JSON Beautifier
Paste your JSON and it gets formatted automatically. You can also validate it, minify it, or explore the structure with a tree view.
About this tool
Paste any JSON and it gets formatted right away. No need to click anything. If the JSON is valid, you'll see the pretty-printed version on the right as you type. If it's broken, hit the Beautify button and you'll get a clear error message telling you what went wrong. You can also minify it down to a single line, or switch to Tree View to click through nested objects and arrays.
