Please don't attach pictures, instead attach code (the actual LabVIEW .vi files). I can't easily "see" the pictures (too small), can't "click" them and see the properties they use, can't test the code, etc.
Your title says "Excel". Do you mean that you want to write a native Excel file (.xlsx) that can (almost) only be opened with Excel, or that you want to write a text file in "Comma separated values" (.csv) format that can be read by many programs (including, say, Notepad)? The latter is quite simple.
If you are interested in using LabVIEW for serious work, you need to spend a little time learning LabVIEW, and getting away from Express VIs and Dynamic Data Wires, both of which "hide" (too) many details and complicate all but the most simple tasks.
