I'm building a language (https://tablam.org) that, hopefully, could become the base for excel/access alternative.

lisp is not the better fir for excel, to see why, check this:

    "The memory models that underlie programming languages"

http://canonical.org/~kragen/memory-models/

Among them, array/relational could be a better fit (semantic and operational). Of course you also need to add some form of reactivity (or actors?) to mimic the immediacy of excel formulas.

To confirm this intuition, check how much pandas/numpy/R lang/apl/Julia/Sql people intersect with the usage of excel.

This means that languages/tools are closer in spirit than lisp.

Also, syntax wise, concatenative langs/array langs/forth langs/sql like is more nice for the terseness of excel usage.

Honestly, Pandas and R are actual Excel killers. At least in certain areas.
