Any Ideas How I can Make this Formating Program Run Faster?

Question

I'm using LabView 8.0.1 to extract columns and rows from MS Excel to format to a specific format which can be read into a software program we use in-house.
The software program requires a specific header which declares variables, etc and also fomats the extracted data in an arcane way.
Due to an error in the software program we use, the file format that has to be read in is not uniform and has the first line containing  two point sets (see attached file for an idea of what I am talking about). Any other format will not be read by the program.
This introduced some problems, and finally, I ended up with an highly inefficient program. It runs, but is relatively slow.
The programs, the input excel file and output file are given for example. 
A couple of notes on the files:
1) The file type used as input is just an excel file which has been saved in space-delimited format.
2)  To speed up the process,I  permitted the formating of only 2 variable types (x, y, z, variable 1, variable 2). I haven't gotten to adding more variables. Ideally, I would like to count the number of columns on the excel file, read the headers and then write the output file automatically with all the variable names.
3) I used sequenced loops in the vi, which is probably not the best way to do this. I am guessing that I can interweave all the numbers into one large array before writing --- but have no idea how I can accomplish that.
The output file extension is actually .fvp. I've renamed it in order to upload the file.
Any help/suggests would be greatly appreciated!!

Answer 1

Use the Format Into String Function instead of the large concatenation.  Most of your inputs are constants, so they could be put into the Format string of that function.  It looks like you have only 2 truly variable string inputs, so they would show up as %s in the format string.
So your format string would be something like this (\codes turned on)  (VI is LV 8.5)
