Python - Read all CSV files in a folder in Pandas?

PythonServer Side ProgrammingProgramming

To read all excel files in a folder, use the Glob module and the read_csv() method. Let’s say the following are our excel files in a directory −

At first, let us set the path and get the csv files. Our CSV files are in the folder MyProject −

path = "C:\\Users\\amit_\\Desktop\\MyProject\\"

Read files with extension .csv from the above path −

filenames = glob.glob(path + "\*.csv")

Let us now write a for loop to iterate all csv files, read and print them −

for file in filenames:
   # reading csv files
   print("\nReading file = ",file)
   print(pd.read_csv(file))

Example

Following is the complete code −

import pandas as pd
import glob

# getting csv files from the folder MyProject
path = "C:\\Users\\amit_\\Desktop\\MyProject\\"

# read all the files with extension .csv
filenames = glob.glob(path + "\*.csv")
print('File names:', filenames)

# for loop to iterate all csv files
for file in filenames:
   # reading csv files
   print("\nReading file = ",file)
   print(pd.read_csv(file))

Output

This will produce the following output

File names:['C:\\Users\\amit_\\Desktop\\MyProject\\Sales1.xlsx','C:\\Users\\amit_\\Desktop\\MyProject\\Sales2.xlsx']

Reading file = C:\Users\amit_\Desktop\MyProject\Sales1.xlsx
