I am programmatically (via C#) placing data on an Excel spreadsheet. Problem
is that some of the data look like dates (e.g "4/22") which really are not
dates. Excel is automatically converting these to dates. When using Excel, I
can set the cell's format category to "Text" and it will display properly.
How do I do that programatically?

add "'" at the beginning of your text.

var = "'" + var

and now Excel will see it as text.
