how to concatenate multiple excel worksheets and files to a dataframe code example

Example 1: merge multiple excel workssheets into a single dataframe

df = pd.concat(pd.read_excel(workbook_url, sheet_name=None), ignore_index=True)

Example 2: merge multiple excel files with multiple worksheets into a single dataframe

import glob

all_data = pd.DataFrame()
path = 'd:/projects/chassis/data/*.xlsx'
for f in glob.glob(path):
    df = pd.read_excel(f, sheet_name=None, ignore_index=True, skiprows=6, usecols=8)
    cdf = pd.concat(df.values())
    all_data = all_data.append(cdf,ignore_index=True)
print(all_data)

Example 3: how to combine number of excel files into a single file using python or pandas

import os
import pandas as pd
cwd = os.path.abspath('') 
files = os.listdir(cwd)  
df = pd.DataFrame()
for file in files:
    if file.endswith('.xlsx'):
        df = df.append(pd.read_excel(file), ignore_index=True) 
df.head() 
df.to_excel('total_sales.xlsx')
