Hello Mbdeck,
In terms of using the Build Text Express VI there is a new KnowledgeBase article that describes how to format the input parameters:
KnowledgeBase 4TQH7BFN: How Do I Use the Build Text Express VI?
What I meant by writing Knowledgeable column headers to the file before the loop is that if you want to write column headers to your file you need to use a separate write to file VI to write the column headers to the file before going into the loop and writing your data to the file.
