Group data frame by column value and save individual groupings to separate excel files  RSS feed

Hi I am very new to python but have been tasked with creating a tool that does the following:
1) opens a csv file
2) splits the data frame up by the values of a single column
3) It will then save those groupings to individual excel workbooks and manipulate the formatting (may add a chart to one of the worksheets based on the newly added Data)

I have found this code, which groups and saves to csv. I can change to the excel format, but I’m really struggling I do the formatting and chart bit. Any help would be very appreciated.

   gp = df.groupby('CloneID')
   for g in gp.groups:
   path = 'CloneID' + str(g) + '.txt'
