    I have never tried this tool so you have to figure it out.
    I used jocover's script and I have to manually match what save folder are from what games.
    It is a pain but better than losing a 300+ hours save files.

    Take a look at my modification to jocover's script, it extracts them into folders in the following format: out/<user_id>/<title_id>/<misc details>.

    Is there any news on going back from checkpoint output back to nand so a save can be reinjected via the USER partition?

    If not what does the conversion do? Does it just unsign the save so resigning would work to reinject?

    Actually I figured this out, your going to need to use BISKEYDUMP, and Lockpick_RCM and get both sets of FULL keys (meaning you will need the sept folder and appropriate files present). Grab the latest hactoolnet release from the github (the one in the zips above throw errors, I assume because I was on a newer FW than when it was released).

    Extract the save using the hactoolnet, remember the file structure here as that is present in the RAW save file, edit the save file (varies between games) and do --replacefile <path in raw save file> <path to edited save file> -k <keyfile that has ALL of your keys> this will put the edited file in the RAW save and resign the save file, inject the save back in to the switch and enjoy.

    I take no risk for you getting banned yadda yadda.

    Could you create a batch that does this?

    You probably could but if the folder structure within the save is inconsistent save to save it would probably result in problems.
