Questions

Why is my JSON invalid?

Common causes are trailing commas, single quotes instead of double quotes and missing brackets. The error message points to the problem.

Do you store what I enter?

No. Your input is processed to give you the result and isn’t saved.

Is this tool free?

Yes. It’s free to use with no sign-up and no limits for normal use.
