I have text fields in my CSV file that contain commas and I have surrounded those fields with double quotes as the documentation says. The plugin is still seeing the commas as delimiters and I get the message "Your file is incorrectly formatted. Please select a valid CSV file."
I can successfully import the file if I remove the commas from the text fields. Also, the quotes get imported if I add them fields.
I tried with this example to double check that I wasn't missing something obvious.
name, age, gender, quote, tags, url
"John", "27", "Male", "Gee, I really like Will's plugin.", "smart, human, Georgia" , "http://www.myysspace.com/pic.gif"
Is invalid while,
name, age, gender, quote, tags, url
"John", "27", "Male", "Gee I really like Will's plugin.", "smart human Georgia" , "http://www.myysspace.com/pic.gif"
works but the values are: "John" "27" etc.. instead of John and 27.
