Configuration Comment Editor
Edit a JSON5 file with comments. Check its values and download standard JSON for apps that do not accept comments.
What happens to comments when I export JSON?
Comments stay in the JSON5 source you edit. The parsed tree and strict JSON download contain values only, since standard JSON has no comment syntax.
