Robustness

Experience shows that Excel is not robust. Each new reporting exercise needs some alterations to the spreadsheet structures. Perhaps the names of linked workbooksare changed. Perhaps formulae need to be dragged down to new cells, or whole new worksheets added. Making those changes is a manual task which can go wrong or be overlooked.

Packola is more robust because the structure needs no changes for a new exercise. Robustness is designed in.
