You may have covered this elsewhere but I couldn't find it.
I had spreadsheets set up in Excel that I wanted to use as the basis for content in the Contacts plug in. After hours messing about getting the data into the right format (all columns identical to the table headings) I then found that it would not let me import the CSV file into my database.
I searched for ages to find something to import CSV into MySQL, then stumbled across
here - it picks up your csv file off your computer and quickly translates it into MySQL (save as a .txt file) so that you can then run the MySQL command into your database.
This may be of use to someone.
