Why would that be hard? I do it all the time in my programs, no database (or 
even persistent storage) in sight. It's easy to read/write .csv files in 
Ada, and I believe that someone even has a library for writing .xls files.

(I'd like a nice spreadsheet program in Ada, too; one would hope it would 
stay up more than LibreOffice Calc does. But I can be a realist when 
necessary...)

The real reason to stick with non-Ada tools is when large parts of the 
system already are in a non-Ada language, and you're just adding to it.

Yeah, proven to make Larry Ellison very rich! The rise of No_SQL has shown 
that it's overkill (and even harmful) in many cases. But off topic to 
discuss here...
