Drop down menu

[TheLearner]

Is there a way of creating these drop down menu's in CSV?

I am currently creating a CSV file, but want to add headings or even better
those drop down columns in CSV?

You can add filters when the file is opened in Excel, but they will be lost
when saved as a CSV.

A CSV is a plain text file, so no.
If you read the CSV into Excel, then you can apply normal Excel facilities
to it, but the CSV itself is just text (which you can read in something like
Notepad).

I am actually creating the CSV file in code - from a .NET application. So
there is no way of creating the filters in CSV?
