pandas combine multiple excel files code example
Example 1: python combine multiple excel files
import os
import pandas as pd
cwd = os.path.abspath('')
files = os.listdir(cwd)
## Method 1 gets the first sheet of a given file
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')
## Method 2 gets all sheets of a given file
df_total = pd.DataFrame()
for file in files: # loop through Excel files
if file.endswith('.xlsx'):
excel_file = pd.ExcelFile(file)
sheets = excel_file.sheet_names
for sheet in sheets: # loop through sheets inside an Excel file
df = excel_file.parse(sheet_name = sheet)
df_total = df_total.append(df)
df_total.to_excel('combined_file.xlsx')
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)
