There are a plethora of plugins to do monte-carlo simulations, linear programming, statistical models and anything else a business user would do in the data analysis world. Vendors include SAS, Oracle, IBM, Predixion. Also Excel is used as a self-service BI tool. It has ETL, OLAP and dynamic dashobarding.

My first job out of college was converting all the Excel spreadsheets that ran the business to web apps so I certainly know how they are used, and more importantly, how they are abused. If Excel had a real scripting language as it's Macro language the problem wouldn't be nearly so bad. All that business code could just be copy/pasted, have some unit tests implemented then refactored so that the accountants code is now updated by the developer. As it is now the code has to completely rewritten in a new language. As for the language choice, VB.Net or C# would be fine. I'm not saying it has to be Python. My complaint is that the code is non-transferrable. The apps cannot grow past Excel, and the email the most recent version to the next guy game gets you into versioning hell rather quickly.

  But you're a developer. A sales manager (for example) couldn't care less about your objections. He wants his pivot tables, KPIs and Solver and some macros. He wants point-and-click ETL. If it's a department/cross-department model, do it in SQL Server, or whatever else you use. You can use your IT kung-fu there. This is about what libre office lacks. Excel has power and flexibility and remains easy to use for non-programmers.

    I agree with those points. My comments are in regards to Macros. Why is VBA better for a sales manager? Why not use VB.Net, Python or C#? There is nothing inherently better about VBA. My issues with Excel come from the perspective of modifying these ad-hoc apps (many business run off these for a long time as they grow). Yes, there are other great features, but for me, for growth, Calc is taking a better approach.

      what were you not able to accomplish with vba? you can use c# with excel as well. http://exceldna.codeplex.com http://exceldna.codeplex.com

  was vba too hard for you to learn?

  Office 2013 has some nascent JavaScript scripting; maybe someday it will overtake VBA.

My company uses SAS fairly heavily for data analysis and bussiness reporting. It's also our go to tool for ad-hoc querries of production databases (essentialy a SQL gui). Excel (and other spreadsheet packages like Calc) are good for non technical users it's useful for rapidly prototyping stuff but it is absolutely a pain for automation and any type of statistical heavy lifting. Once a spreadsheet reaches a certain level of complexity it becomes a pain to support and maintain much better to have a real database driving things. I've heard a lot about R which is kind of an open-source version of SAS (at least the statistical parts) not sure what its automation and reporting support is like my limited understanding is it doesn't have the BI parts.
