I was wondering about the quotes
Thanks skwire -- it opens perfectly in Libre Office
I was using Softmaker's Planmaker -- I will report it to them when I get a chance (I'm otherwise very happy with their office software)
Planmaker can also open them correctly, there's an option you can select when you import a CSV file to tell it to regard items with quotes around them as one cell.
I've done it importing Amazon reports where item descriptions often have a comma in them.
Currently on the tablet, I'll look it up in a few hours when I'm awake
