[Blocker] No universal conversion to strings

[9il]

Motivation

A table contains dates, numbers, and strings (headers, and NaNs).
So it should be convertible to a universal type like string[][] or Variant[][].

How to reproduce

Change the function in the example to FuncBob

Note

Text cell formatting does not help.

BTW, Date support for an excel-d algebraic type would be very nice to have.

There's a type called Any.
It's a variant that supports exactly the same types as Excel does. Just declare your function to take Any, Any[] or Any[][]. Unfortunately that means knowing how Any works and manually inspecting the type (it contains an XLOPER12 inside.

Check the date functions in xlld.xlf - Excel uses double as a date type. There's no automatic conversion right now though - I agree it'd be nice to automatically convert to/from std.datetime.DateTime.
