Frequently Asked Questions
Is my JSON data sent to a server?▼
No. All formatting and validation happens locally in your browser. Your data never leaves your device.
What is the difference between Format and Minify?▼
Format adds indentation and line breaks for readability. Minify removes all whitespace to produce the smallest possible JSON.
