Is it possible to convert Dropbox files (sp-achive.json and sp-main.json) to a .json local backup file?

[diegopds83]

I use GNU/Linux Debian 12 Bookworm (witch Super Productivity .deb package version 11.1.3 and now 12.0.1) syncing with Dropbox.

On 2025-03-25 my database was corrupted after a quick power outage (I use a desktop PC and don't have a UPS).

When this happens, I usually restore the backup from the previous day... But in the latest versions, Super Productivity's automatic backup generation is not working.

The last local backup I have is from 2025-03-12.

On Dropbox, there is a version history of sp-achive.json and sp-main.json files. But I can't synchronize the data through Super Productivity because of the problem reported here: #3617

My question is: is it possible to convert the sp-achive.json and sp-main.json files to a .json local backup file to restore my database?

Yes! But you have to mush them together by hand :)
