If you are a beginner in LabVIEW, before taking on an intermediate task like integrating LabVIEW (one programming paradigm) with Excel (another paradigm), learn as much as you can from the on-line tutorials (see, for example, the upper right corner of the Forum's Home Page) and do as many of the exercises as you can.
There are numerous examples of reading and writing LabVIEW data to and from Excel Workbooks, both here in the Forums and on the Web. The simplest way to do this involves the Report Generation Toolkit, now included in the base LabVIEW 2014 and LabVIEW 2015 installations.
In dealing with Date information, one needs to be a little careful. If the dates can be read and written in String format (that is, "26 Nov 2015, 13:42" or something similar), it just becomes a matter of each side being able to parse the string into their own (different!) internal representations.
