I want to create an Excel workbook with a certain number of sheets, and fill the cells with numeric and string data (in Delphi 2). Ok, I discovered the function CreateOLEObject, but 1. How to create a workbook? 2. How to create sheets in it (with a given name)? 3. How to select the sheets, and put data into the cells? 4. And last, how to save the workbook?
