org.apache.poi.hssf.usermodel.HSSFFormulaEvaluator.evaluate()
If cell contains a formula, the formula is evaluated and returned, else the CellValue simply copies the appropriate cell value from the cell and also its cell type. This method should be preferred over evaluateInCell() when the call should not modify the contents of the original cell. @param cell may be null signifying that the cell is not present (or blank) @return null if the supplied cell is null or blank

    }
