JSON editor FAQ

Can JSON use single quotes?

Standard JSON requires double quotes for strings and property names, unlike JavaScript single-quoted strings.

Does successful validation mean the data is correct?

It means the syntax parses. Field types, business logic, and API constraints are not checked.
