how to get rid of pandas converting large numbers in excel sheet to exponential?

The way scientific notation is applied is controled via pandas' display options:

pd.set_option('display.float_format', '{:.2f}'.format)df = pd.DataFrame({'Traded Value':[67867869890077.96,78973434444543.44],                   'Deals':[789797, 789878]})print(df)       Traded Value   Deals0 67867869890077.96  7897971 78973434444543.44  789878

If this is simply for presentational purposes, you may convert yourdata to strings while formatting them on a column-by-column basis:

df = pd.DataFrame({'Traded Value':[67867869890077.96,78973434444543.44],                   'Deals':[789797, 789878]})df    Deals   Traded Value0   789797  6.786787e+131   789878  7.897343e+13df['Deals'] = df['Deals'].apply(lambda x: '{:d}'.format(x))df['Traded Value'] = df['Traded Value'].apply(lambda x: '{:.2f}'.format(x))df         Deals       Traded Value0   789797  67867869890077.961   789878  78973434444543.44

An alternative more straightforward method would to put the following line at the top of your code that would format floats only:

pd.options.display.float_format = '{:.2f}'.format
