Frequently Asked Questions

Does this upload my JSON?

No. Formatting and validation happen entirely in your browser. Nothing is sent to TeaFun servers.

Can it minify JSON too?

Yes. Use Minify to remove whitespace for compact payloads, or Pretty print to make JSON easier to read.

What happens on invalid JSON?

The tool shows the parser error plus the best available line and column so you can fix the broken part quickly.
