Frequently Asked Questions

Q: What does syntax checker show?

If your JSON is invalid, the browser parser will catch the syntax exception and print the exact error description and token location to help you debug quickly.

Q: Are my JSON variables saved?

No. The parsing and rendering are local client processes. Your data never touches a network server.
