Answers for "combine multiple excel files from folder to dataframe"

export multiple python pandas dataframe to single excel file

#1. Create a pandas excel writer instance and name the excel file
xlwriter = pd.ExcelWriter('Customer_Details.xlsx')
#NB: If you don't include a file path like 'C:UsersRonDesktopFile_Name.xlsx'
# It will save to your default folder, that is,
#where the file you're reading from is located.

#2. Write each dataframe to a worksheet with a name
dfName.to_excel(xlwriter, sheet_name = 'Name', index = False)
dfAddress.to_excel(xlwriter, sheet_name = 'Address', index = False)
dfContact.to_excel(xlwriter, sheet_name = 'Contact', index = False)

#3. Close the instance
xlwriter.close()

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)
