There are known bugs (for years now) with the LastPass exporter regarding special characters such as the ampersand (&), the greater than sign (>), and the less than sign (<). The LastPass exporter may change (HTML encode) these and possibly other special characters in your passwords to their respective HTML encoded values (ex. &, >, and <
. If this LastPass bug affects your exported data you should use a text editor (such as Notepad) to find and replace all of these values before importing into Bitwarden. For example, you may want to do a find and replace for & → & and < → <).
Alternatively, you can use the
LastPass Pocket application to export your CSV data. The LastPass Pocket application does not appear to be affected by these bugs.
