JSON is everywhere — APIs, configs, data exports — and one missing comma can break everything. Manually scanning braces is a waste of time. Here's the fast workflow:
1. Paste your JSON
Copy the raw text from your API response, log file, or editor and paste it into a formatter. No need to clean it up first.
2. Validate
Hit validate. A good tool doesn't just say "invalid" — it tells you the exact line and column of the error. The most common culprits: trailing commas, single quotes instead of double quotes, and unescaped line breaks inside strings.
3. Format or minify
Use formatted (indented) output when you're reading or debugging, and minified output when you're sending it over the wire or pasting it into a config where size matters.

Beyond formatting: convert JSON
Sometimes you don't need prettier JSON — you need a different format. The formatter includes one-click converters: JSON to XML (for legacy APIs and SOAP services), JSON to CSV (open arrays of objects straight in Excel or Google Sheets), JSON to YAML (for Kubernetes and CI configs), and JSON to escaped string (to embed JSON inside code). You can also upload a .json file directly, pick your indentation (2/3/4 spaces or tabs), enable auto-format as you type, and download the result.
