Why use the WhiteArray JSON Formatter?
Working with raw JSON data can be a nightmare. APIs often return massive, unformatted blocks of text that are impossible to read or debug. Our JSON Formatter solves this instantly by parsing your data and returning a beautifully structured, indented string.
100% Client-Side Privacy
Unlike many other online formatting tools, WhiteArray processes your JSON entirely in your browser. Your sensitive data, API keys, or proprietary configurations are never sent to a server, never stored in a database, and never logged.
Supports Loose JSON (JSON5)
Have you ever copied a Javascript object with trailing commas, unquoted keys, or comments, only to have standard JSON validators reject it? Our tool uses JSON5 parsing, meaning you can paste messy Javascript objects and it will automatically clean them into valid, strict JSON.
Features
- Beautify: Adds proper indentation (2 spaces) and line breaks.
- Minify: Removes all whitespace for the smallest possible payload size.
- Validate: Instantly tells you if your JSON is valid, and points out where the syntax error is.
- Copy to Clipboard: One-click copy for your formatted output.
