Describe the improvement

I was working on setting up a new computer and tried to import a JSON file to winget that I exported with WingetUI only to find out the schemas are different. I'm trying to automate things so WingetUI wasn't installed yet. I think there should be an option to export to the JSON format that winget can use.

Describe how this improvement could help users.

Since the purpose is to be a UI for winget, it should have a compatible JSON import/export file to maintain interoperability. Also makes automating easier.

but wingetui exports packages that winget can't install. Do you mean manager-specific package lists?

I suppose. I only use it for winget so I didn't think about that. I tried to automate importing to winget on a fresh Windows install that didn't have wingetui yet but it was the wrong format.
