Use the Read From SpeadSheet File.VI which you can find on the FILE I/O pallette.
"
Read From Spreadsheet File
Reads a specified number of lines
or rows from a numeric text file beginning at a specified character offset and
converts the data to a 2D, single-precision array of numbers. You optionally can transpose the
array. The VI opens the file before reading from it and closes it afterwards.
You can use this VI to read a spreadsheet file saved in text format. This VI
calls the Spreadsheet String
to Array function to convert the data."
The CSV file is essentially a text file which uses commas as delimiters in the files structure.
