I dont think a formal grammar exists but this link should be helpful.

I have also written a more limited parser that parses out functions and
defined names.

What did you want one for?

Hi,

I am looking for a grammar of excel formulas in any format(EBNF, BNF, yacc
or in other notation). Is any around?

Thanks in advance!!!
