Text and data File re format program

I Require a stand alone EXE program to run on Win 7 or Win10 which re formats a data file. The input file is from a high speed data logger, which collects readings from various instruments and sequentially writes them to a text data file. There are 9 different types of lines written to the file, each line type relates to a different instrument being sampled. The Re-formatting program should pad out readings with commas so that the data from each instrument is in its unique column of the output CSV file. Some of the readings are written in 16bit Binary format which should be converted to ASCII. A unique header with the column names should be added to the top of the file. Data files can be upto 450Mb in size A word document with more explanation and example is attached. Small sample input and output files are attached. Require program completion quickly.
