@harshavardhinip The connectors available for Excel allow you to do this. The GetCellValue method allows you to get the value of a cell. The SetCellValue method allows you to set the value of a cell. Both of these methods take the row and column as parameters to help you determine where you wish to read or write data from or to. If you are having a specifc issue or question with one of the connectors, please upload your sample solution and I can certainly take a look at it for you. In your case, I would probably use a ForLoop to output what your row should be for a given iteration. You would set the Initial and Limit values of the loop accordingly (Excel rows start at row 1 which is typically your header row). The Index property of the ForLoop would be used as the Row parameter in your SetCellValue method.
