Expanding upon the previous answer, you can dump everything out to a .csv file to sort and play around with in your favorite spreadsheet application.

import pstats,StringIO

# print stats to a string
result=StringIO.StringIO()
pstats.Stats(filename,stream=result).print_stats()
result=result.getvalue()

# chop the string into a csv-like buffer
result='ncalls'+result.split('ncalls')[-1]
result='\n'.join([','.join(line.rstrip().split(None,6)) for line in result.split('\n')])

# save it to disk
f=open(filename.rsplit('.')[0]+'.csv','w')
f.write(result)
f.close()
