I don't understand... are you referring to the data used or generated by the VI, or the actual code? If you're talking about the actual code, the answer is no. This is a frequently asked question. LabVIEW code is code. It's not C, it's not C++, it's not text-based. While there exists a conversion to C for the embedded version, it's extremely limited and not intended for general use.
If, on the other hand, you're talking about the data, you can save the data any way you want with the File I/O functions.
