While converting the Excel document into PDF, the cell values are calculated based on the cell type. In the input document, cell type for the formula containing cell is serialized as string type. But, the result of the formula is a number. Due to this conflict in cell type, XlsIO cannot get the actual data for the chart and cell alignment also set incorrectly. So, Excel to PDF conversion is not same as input document.
