Here you go:
This is the front panel of the small program after running it: it contains a file path to your data file and a 2d-array indicator with the data read
this is the diagram ('source code') of the program: it uses a .vi 'Read from spreadsheet file.vi' delivered with the labview system (it is the second entry in the 'Functions->File I/O' menu) it reads ASCII data and converts to single precision binary values (SGL).
the only special thing to note here is the format specifier "%.;%g": the %.; defines period as decimal separator (my PC uses comma as default, so I had to use this) and the %g is the conversion code for any engineering format.
