andycl, do not worry I will provide you with the VBA code today.
There are 2 methods to do this, the first is to use a combination of Winxmun's code and yours, Winxman's to segment the data in to it's Records and your Split routine to parse it into fields. I do not like this method because of the limit it puts on the number of records in the text file exceeding the 65,000 character string length.
Method 2, using Input takes me back to my original BASIC training in the 80s when I built databases where all data was input and output 1 character at a time.
It might be a bit slower than line input but it will do it.

If the owners of the data were to change the vblf to Carriage & returnlinefeed the line input would work OK.

ps do you want to keep this data as 1 field "BFN-2-XM-046-0018/16, RFWCS NODE BUS INTERFACE" as jonh says, this combines " and , in one field and parsing with Split would split it in to
"BFN-2-XM-046-0018/16,
&
RFWCS NODE BUS INTERFACE"
