Answer 1

you need something like this : don't get confused with the naming convention as this is one of my code. the problem is

  DataFormatter fmt = new DataFormatter(); String _charges = fmt.formatCellValue(sheet.getRow(45).getCell(CellReference.convertColStringToIndex("D"))); 

what you are doing is trying to fetch a numeric value from the sheet whereas it is saved as a String so you need to convert it to String before you can use it. The code i have pasted is not the exact solution but i hope you might get the hint about the solution.
