Thanks for trying out Codebook and sorry for the trouble importing from KeepassXC.
I just took a look at the export format from KeepassXC and it does appear different than what we’re expecting for importing into Codebook (hence the error message you received). I’m not sure at this point whether the format has changed recently or whether it differs between Keepass vs KeepassXC. We’ll look it further.
In the mean time. I’d like to provide you with steps to manually modify your CSV to allow direct import into Codebook using the standard CSV import format:
Open the KeepassXC CSV in Numbers
Change the Group column header to Category
Change the Title column header to Entry
Delete the Icon column
File > Export To > CSV and save it somewhere (like your Desktop).
Within Codebook, File > Import > Import CSV and select the modified CSV you exported in step 5.
Let me know if that allows you to import your KeepassXC data into Codebook. Thanks!
