@fabrixx Welcome to the forum!
Seems that Bitdefender has made significant changes to their file format since a year ago.
I will try to help you, but to do so, I will need you to follow some instructions and provide answers to some questions, OK?
First, start by making a copy of the exported CSV file (because you will be deleting data from the file in preparation for importing into Bitwarden; by working with a copy, you don’t have to worry about losing any important information that may be contained in the original export file).
Second, open the copied CSV file in a spreadsheet app (like Microsoft Excel, Google Sheets, or LibreOffice Calc — please let me know which one you are using, in case I need to provide specific instructions).
Third, delete every row that contains data for an Identity item or a Credit Card item (as these cannot be imported). Make sure that these rows are completely deleted, and not left as empty (blank) rows.
Fourth, delete every column that is blank (i.e., no data in any row, except for the column title in the top row).
Fifth, save the file with all changes made so far.
Finally, copy the first row of the file, and paste it in your response (so that I can see what columns remain after you have done the deletions as instructed above).
It would be great if you could also provide a brief description of what type of information is contained in each column.
