Sure! Was hoping to test it a bit further before sharing in the open (E.g. no one else has verified that the intervals are actually imported correctly yet. Also, am not too keen on playing Support Agent for this process), but here’s to hoping it’ll just work 
If you do happen to improve upon anything, like making the google sheet include more of the Jalup cards or making it more robust (I’m not the best at formulas within excel) please share with everyone so they can save themselves the work.
In case you discover I messed something up big, please let me know 
Things worth knowing:
- The google sheet refers to specific Card-IDs within Anki. I took the ones that I got when loading the decks into Anki, but I don’t know if cards get the same IDs even if you follow the same process step by step. Please check that the IDs in the google sheet match up to the cards you loaded into Anki.
- The google sheet I linked only includes JB+JI+JA+JE+JH
- The sheet I set up sets the ease on all cards to 300%. (Anki default is 250%, Jalup has its own ease rating for each card.) If you want to change that, you’ll need to adjust column D in your google sheet. (I believe the Jalup ease is also column D within the JalupBackUp file? Seems like you just need to multiple the column with 1000 to make it compatible with the Add-on.)
- This doesn’t import freezes, because I don’t think the Add-on had that option. Freezes will be set as new cards.
- Personal notes are currently not being imported. I don’t think you can do this with the Add-on either, so one would have to figure out a separate step.
- I loaded the decks into a separate profile as to not mess anything up with my old one and possibly make cards getting the same CardID across different users more reliable. You can export the re-scheduled deck at the end and load it into your own profile. (Easier to make a stacked deck like Jalup::1_Beginner::Stage01 for exporting)
- Load the Anki decks into a new, separate profile. Do it in order. (So JB Stage 1 → JB Stage 2 → … → JI Stage 1 → … → JA Stage 1 → … JE Stage 1 → … → JH Stage 1 → … → JH Stage 4. No idea if it matters, but that’s the order I did it in)
- Install the Add-on 891862080 by going to Add-ons → Tools → Get Add-ons
- Go to Jalup→Anki(JB+JI+JA+JE+JH) - Google Sheets and create a copy on your own google account. (File → make a copy)
- While the “Jalup Backup” tab is open in your google sheet, import your JalupBackup.csv with the settings shown in the screenshot attached
- Download the “Jalup Backup Converted” as a comma separated csv
- Load the converted csv into Anki with the Add-on you installed through Tools → “Import card scheduling info from CSV”
*No Pandas are liable in case you discover a month from now that some of your progress was messed up. Please double check the imported intervals yourself (e.g. by comparing Anki intervals with the original JalupBackUp.csv)
