I don't know this "Christopher Relf" guy - but he sounds like he's awesome! Please give him my details - I'd love to offer him a job (I bet he's really handsome too, and smart, and witty, and humble...)
Anyways, yep - it's that rogue "," that's the issue, and parsing is the only way out of it. Excel does some "smarts" by not parsing text between the " and ", but the LabVIEW functions are more base, allowing for far more flexibility. Alas, with more flexibility come less smarts - you need to include that yourself
I like Mikkel's answer - it's probably the cleanest you'll get. Another option is to go through the raw test once it's read in and replace the delimters outside the quote with a different delimter (say, \t) and then parse into an array.
