I have this excel worksheet
A B c
foo1 joo1 loo1
foo1 joo2 loo2
foo2 joo3 loo3
foo2 joo4
Also you could use Salstat2, and the following steps
1- import the data by using the option open in the file menu
2- Into the script panel you should write
# getting the colums
res= group()
res.xdata= [ grid.GetCol('A')]
res.ydata= [ grid.GetCol('B'), grid.GetCol('C')]
res.yvalues= ['concat(B)','concat(C)'] # concat is a function used to concatenate the data
report.addPage() # adding a new sheet to put the results
for lis in res.getAsRow():
report.addRowData( lis) # adding the results row by row
