I am planning to move the contents of a JTable into a Microsoft Excel sheet. The Excel sheet should have some format specifications. For instance if a column has a value 'A' it should be green in colour. If it is 'B' red in colour.
I am in analysis stage. Which Jar should I use? The data is not huge.Performance is not a big concern.
I would recommend Apache POI. It is easy to use, allows styling, etc. See the quick guide here.
