Frequently asked questions

Is my JSON data sent to your servers?
No. All processing happens entirely in your browser using JavaScript. Your JSON never leaves your device.
What does "Format" do?
Format (pretty-print / beautify) parses your JSON and re-serialises it with 2-space indentation and line breaks, making it easy to read.
What does "Minify" do?
Minify removes all unnecessary whitespace and line breaks, producing the most compact valid JSON. Useful for reducing API payload size.
What does "Validate" do?
Validate checks whether your input is valid JSON and reports any syntax errors with the exact line and column number.
What are the key count and depth stats?
Key count is the total number of keys across all objects (including nested ones). Depth is the maximum nesting level. These help you understand large or complex JSON structures.
