Labview VI

Problem:

I mistakenly logged data in labview signal express with out a buffer i.e one sample taken with a 1Hz sampling rate. Each new data point has a new header and as a result cannot be made viewable or converted to a text file. I have seen VIs that can maximize the buffer and rewrite the file with a single header but I have been unsuccessful in entering all the correct information into actual VI.

Can someone please advise or walk me through the process?

Thank you
