EPPlus Off-by-One Fix

I'm updating some old code, and want to replace some code to create excel documents with EPPlus. The problem is my old code indexes things from [0, n-1] and EPPlus indexes from [1, n].

Is there any way to account for this, other than to manually increment all cell addresses by [1,1]?

Solution

So an interface which reads in indices at [0,n-1] and then increments the values before calling the appropriate methods probably would have worked, but for personal reasons, I couldn't use this approach.

Things that helped me:

Where I was using variables purposed for indexing, I could increase their initial value by 1.
Large sections of relatively repetitive code (same operations, different cell ranges) into small loops where there were less values to manage.
Helper methods for commonly used formats for were also very helpful in preventing me writing the same range multiple times.

Beyond that, however, I unfortunately didn't find a simpler way than to add [1,1] to everything.
