When saving an excel sheet (xls - 2330) in .xml form, the xmlss file will contain the respective xsl code. But in xlsx i can't save the file with .xml format.
Also is there any specific Apache POI API availabe to convert .xls (2003) to .xlsx(2007) format?
Since the POI creates the xmlss file to create the xlsx, is there any simpler option?
