I wouldn't say it was extremely simple but I managed to move our company from LastPass to Bitwarden a few months ago. There is definitely an export & import process available. I did have to do some minor CSV cleanup on what LP generated though. Additionally, I purged and repeated the import process a few times once I familiarized myself with how "Collections" and company-wide sharing works in BW. But in the end it was certainly worth it despite the effort.
Yes - you can dump out your passwords from lastpass as a CSV and slurp them straight into Bitwarden.
I switched from Lastpass when they started demanding more money - and whilst not perfect, am very happy with Bitwarden. Functionality is all there, just a bit clunky in places - but you get used to it.
