I have been looking into Enpass due to is wider range of support over Dashlane, which is my current solution, but I am having issues importing the Dashlane data into something usable.  Instead of proper cards, it is just giving me generic cards with generic fields in them, it doesn't look like its mapping any of the data over, and it's not giving me an option to map the fields myself.  Any help resolving this would be appreciated.

First of all, thanks for trying Enpass and writing to us. 

Unfortunately the CSV file exported by Dashlane has many issues affecting the clean import of all items. They are like; partial export of data in CSV, Indefinite number of columns and other formatting problems. So, It is nearly impossible to make a good importer. 

However the best workaround at the moment is to create your own custom csv by editing the Dashlane’s exported file. Open that in a spreadsheet program and copy columns to a new CSV with format described in this FAQ.

After that you will be able to import your passwords using Generic CSV importer.

I had exactly the same feedback; thanks for the tip.

It would be great if you could 'convert' the generic card into the other types. At the moment I'm copying the details out of the card and into a new card manually.
