Need automate the creation of a powerpoint presentation that uses an excel fiel as the data sourca. Each powerpoint slide will have a legend propoerly formatted that comes from an excel file row. The number of slides will depend on the number of rows. For example if the excel file has 3 rows with values like "row1", "row2" and "row3". The powerpoint file will have 3 slides each with a legend "row1", "row2" and "row3". The legend must have special fomat and can't be a manual link to excel.
