❓ Frequently Asked Questions
What is JSON?
JSON (JavaScript Object Notation) is a lightweight data format used to store and exchange data. It's easy for humans to read and write, and easy for machines to parse and generate.
What does "Format/Beautify" do?
Formatting takes your JSON and adds proper indentation and line breaks, making it readable and easy to debug. Minified JSON is compressed into a single line, ideal for production use.
What is JSON validation?
Validation checks if your JSON is syntactically correct. If there's an error, we'll tell you exactly where the problem is (line number and error message) so you can fix it quickly.
Is my data secure?
Yes! All processing happens entirely in your browser. Your JSON data is never sent to any server - it stays on your device. Perfect for working with sensitive data.
What is the difference between Format and Minify?
Format (beautify) expands JSON with indentation for readability - great for development. Minify compresses JSON to a single line to reduce file size - ideal for production.
Can I copy the formatted output?
Yes! Click the "Copy" button to copy the output to your clipboard. You can then paste it anywhere you need.
What is the maximum JSON size?
There's no strict limit, but very large files may slow down your browser. For best performance, we recommend JSON under 10MB.
