Python script to compare and merge excel files

Here I’m talking about a cool Python module using that you can compare two sheets in an excel sheet for a common value and merge the sheets.

First you need to install the module “pandas” for the solution. Python script is as below :

import pandas as pd

source1_df = pd.read_excel('a.xlsx', sheetname='Sheet1')
 source2_df = pd.read_excel('a.xlsx', sheetname='Sheet2')
 joined_df = pd.merge(source1_df,source2_df,on='Serial',how='outer')
 joined_df.to_excel('result.xlsx')

Note : replace the sheet1 and sheet2 with actual name of the pages and use the correct primary key name(Here “Serial”; case sensitive)

Eg :
sheet1 as below

Serial	Hostname
123	abc
234	bcd
345	cde

 

sheet2 as below

Serial	Model
234	Sparc
345	IBM
567	HP

 

After executing the python script, output comes  as below :

	Serial	Hostname	Model
0	123	abc
1	234	bcd	Sparc
2	345	cde	IBM
3	567		HP
