> replace Excel for business users Not likely. Given the depth and breadth of its penetration, all the man-millenia that have been spent encoding business rules in Excel, I suspect that in the end Excel will outlive Windows itself, just as COBOL has outlived the mainframe era. I'd love to see a principled approach to extending Excel, and maybe MS have already done it. There are a lot of ways to extend Excel, and given the MS practice of keeping backwards compatibility alive for decades, none of them is going away any time soon. Could be one of them is actually good. I just today learned about Power Query M, which looks promising.
