Excel formula pasrsing - BNF, Yacc?
I dont think a formal grammar exists but this link should be helpful.
http://ewbi.blogs.com/develops/2004/...formula_p.html I have also written a more limited parser that parses out functions and defined names. What did you want one for? regards Charles ______________________ Decision Models FastExcel 2.1 now available www.DecisionModels.com "arthur" wrote in message ...

I need it for some specific tasks, where a parser will travers all cells (or
specific) and collect some information based on a formula from those cells.

Charles,
I've came up with Excel grammar (took some time though:)). If u r interesting I can forward u too. Not sure if it covers 100% of Excel features.
