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.
