I have two excel files containing multiple lines of excel from a datalogger, and I need to compare the two files with 3 similar columns (anum,bnum,date,time) but with different column durations, and then save the difference into a third excel file.



***excel file 1:

          You can first read both excel files using pandas.read_excel
          into two dataframes df1 and df2 Then : 



          df1.rename(columns={'duration':'duration1'},inplace=True)
          
df2.rename(columns={'duration':'duration2'},inplace=True)
          
df=df1.merge(df2)
          
df['duration']=df['duration2']-df['duration1']
          
writer = pd.ExcelWriter(excel_file_3)
          
df[['anum','bnum','duration','date','time]].to_excel(writer,'Sheet1')
