Hi i came across http://poi.apache.org/apidocs/org/apache/poi/xssf/usermodel/XSSFWorkbook.html and http://jexcelapi.sourceforge.net/ not sure with is more stable and popular.
I will be using this within Spring Framework though particulary Spring Batch. I was hoping that Spring would have an API for such.
You inputs will be well appreciated.
The Apache POI API is more popular and updated, as you can see from jexcelapi it only supports up to excel 2003.
Spring does not have an Excel API built in, you would have to use an external one.
