I recently had the challenge of improving upon an Excel workbook. This was a complicated sheet, with 200 columns of ugly calculations that solved a difficult engineering problem. There were many rows, one for each widget being engineered. I'm going to blog about several issues I encountered for this.
The first issue I needed to deal with: should I extend Excel (with VBA) or rewrite the application in .Net. I see the following pros and cons:
|Extend Excel with VBA
|Rewrite in .Net
The final solution I'm looking at: make a hybrid. Continue using Excel for user input and calculations, extending it with VBA. But use .Net to read the Excel document and generate output views. I'll discuss this more in my next blog.
