About the JSON Empty Value Remover

The cleanup works bottom-up, so an object left empty by having its only field removed is itself removed. One pass is enough.

As with nulls, "empty" and "absent" are not always the same thing to the system receiving the document.

Questions people ask

Is your document uploaded to a server?

Is it free, and do I need an account?

Yes, it is free, and there is no account, no sign-up and no watermark on the result. The project is funded by optional donations.
