I'm following this thread and the code posted by Hehabr to help myself learn the POI. I'm going very slowly, doing this as time allows for me. I have not yet put all of Hehabr's code (in POITestEva) in my own corresponding Java project that tries to track Hehabr's. Rather, I'm adding methods slowly so I can study them. I'm using POI-3.17-Beta1 for this.
I notice that Hehabr appears to be opening and writing to an Excel *.xlsm file which could contain embedded macros. I'm not sure if this has an effect on the POI. I have been playing with the HOWTO and Quick Guide examples in other contexts, also to learn, and I agree that the DataFormatter is very nice. I played with it in a separate project. I have not yet added it to Hehabr's code but I'll likely do that. Also I will learn to evaluate formulae. Best of luck to you, Hehabr!
