Does this JSON formatter store my data?
No. All formatting happens locally in your browser. Your JSON never leaves your device.
Can I minify JSON as well as beautify it?
Yes. Toggle between pretty-print and minified output with one click.

ToolBay does not store your input. Close the tab and it is gone. More developer tools.
