Convert old format to current format.

I have a list.json created in 2017 I keep reusing. Whenever I import it, it warns me to "update" it to the latest version, but still works for a while before it "unimports" it. This time is becoming shorter and shorter, now within the same day. Can I conjvert it somehow, or do I have to create a new version of my incredibly LONG list of substitutions?

If by "unimport" you mean that it's deleted, then that should not happen, there must be some problem.

However, to update it you only need to export it after import.

I exported it, and the file is always there but the list still becomes blank periodically.

It could be a problem with your computer or some specific configuration of Firefox because as far as I know it does not happen to anyone else.
