Hello Everybody, So Today I just faced this issue of merging multiple excels in one and there size was too big for merging like more 100 MB for Size and In Some Cases the size spans more and if we tried to search any online tool they mostly have size limit for merging the excel files with same columns.
I Know there is pd.merge function but I like simple.
So I Just Decided to merge my file as given below.
So My Code Is in Jupyter Notebook and I am Pasting it's Markdown version as given below.
Firstly we will need to Import pandas and glob package
pandas
for dataframe and glob for getting the list of all files in whatever folder that we want
import pandas as pd
from glob import glob
Get List file all file names in a variable named list_of_all_files
like given below
list_of_all_files = glob(r'B:\dev\test_folder\*.xlsx')
list_of_all_files
['B:\\dev\\test_folder\\test.xlsx',
'B:\\dev\\test_folder\\test2.xlsx',
'B:\\dev\\test_folder\\test3.xlsx',
'B:\\dev\\test_folder\\test4.xlsx',
'B:\\dev\\test_folder\\test5.xlsx']
Read Each and Every file and get list of Pandas Dataframes
all_dfs = [pd.read_excel(file, 'Sheet1') for file in list_of_all_files]
all_dfs

Now we are gonna merge all data frames in one, like given below
Be Aware that at given below line of code the ignore_index=True is mandatory because the index column can be duplicate for each file and may overwrite instead of merging all df into one.
single_merged_df = pd.concat(all_dfs, ignore_index=True)
