There is no general-purpose program or command to convert data in a .txt
file to CDL, becasue of the great variety of ways to represent data in
a .txt file.  In general, you need a program or script to do this.

How you do this depends on whether your data is multidimensional, how
much metadata you want to include, whether you want to include a
coordinate system, what netCDF conventions you choose to follow (for
example CF Conventions), etc.

It might be easier to get your data into a form with comma-separated
values, because that's what CDL uses.
