Aderogba submitted a good program, but you should note that if you want to read a spreadsheet file you will need to know how the columns are delimitted. Aderogba's program assumes a Tab-delimitted spreadsheet file. Tab-delimitted is one of the most common methods, but if you are using Excel (for example) you must specifically save your spreadsheet as a Tab-Delimitted Text file before you can read it in from LabVIEW.
