Frequently Asked Questions
- Is my JSON data secure?
- Yes, the formatting is done entirely in your browser. No data is sent to our servers.
- Why am I getting an "Invalid JSON" error?
- This usually happens if you're missing quotes around keys, have trailing commas, or are using single quotes instead of double quotes.
- What is "Minify" used for?
- Minifying removes all unnecessary whitespace, making the JSON payload smaller and faster to transmit over the network.
