Upload .csv file by line to one field of a database entry

Hello all,

I would like to upload a .csv file by line to a field of an entry in my database. (I received a lot of codes in a .csv file and I have a field for those codes in each entry in my database).

How can I do that? (Either with a workflow or manually.)

When I try to simply upload the file/copy the text from the file bubble handles it as one entry, instead of the comma-separated format.

Any help would be appreciated.

Thanks.
