When I go to Import in the (freshly downloaded and installed) 1Password app on Windows 10, it presents only two options: '1Password Interchange Format' and 'AgileKeychain or OPVault folder'.
I was able to do it no problem on the 1password website. So I no longer need help, but the general issue remains.
Hey there @brieh, welcome to the 1Password Support Community! 🎉 Thanks so much for writing in - I'm glad you were able to import your data successfully!
The Windows desktop app currently supports importing data from 1Password interchange format (1PIF) and AgileKeychain/ OPVault folders. To import from a CSV file, we suggest doing so at 1Password.com. For more info on importing data to 1Password, I've included a handy link below:
