How to Read and Insert CSV data into Database | Python Tutorial

In the fast-paced world of data management, efficiency is key. Whether you’re a seasoned developer or someone taking their first steps into the realm of databases, the ability to smoothly transfer data from one format to another is a valuable skill.

One common scenario involves extracting information from CSV (Comma-Separated Values) files and seamlessly integrating it into a database.

Read And Insert CSV File Into Database

If you’re visual learner , below is the full tutorial video:

Read Data From CSV And Insert Into Database

Create the Database connection

To create database connection , at first, we need to import the database .So, lets see how can we import the database .

Import Database

At first, you need to import the Database into the Python file by : import MySQLdb

To import it , MySQLdb must have been installed in your computer. To install it, go to: Download MySQLdb

Open CSV File And Read

We need to create the CSV file and import it .

Opening CSV File

To have access to CSV file , first, you need to import it. For that: import csv

Now, you need to open the CSV file that you have prepared. To open :

with open('xyz.csv') as csv_file:

Reading CSV File

After opening the CSV File , now need to read and append the csv file into the single variable which stores all the data in database.

with open('xyz.csv') as csv_file:
csvfile = csv.reader(csv_file, delimiter=',')
for row in csv file:

The code above reads the csv file and and append reach row in ‘all_value ‘ in the database. The code is for the three different elements in a row in csv file ,that’s why there is 3 index 0,1 & 2 for a row. It can vary according to the number of elements in a row you have in csv file.

Insert Into Table

After we read and append the csv file , now we need to insert the data into the table of our database.

To insert the data into the table, the code below is used:

query= "insert into `table_name`(`name,`company`,`launch_year`)values(%s,%s,%s)"

In the above code, name, company and launch year are the attributes in the database table named as ‘table_name’ and its values are stored in the database.

Execute The Query Using Cursor

After inserting the data into database , we now need to create a cursor to query a database .

Create a cursor To Query A Database

In order to execute the query, we need to create a cursor for our database.

we can create a cursor for our database and use it to query a database. To create the cursor ,

mycursor = mydb.cursor()

Here, mycursor is the cursor name and mydb.cursor creates a cursor named mycursor.

Execute The Query

Now , to execute the query by using the cursor we created earlier:


Commit The Changes

Finally, after doing all the necessary steps successfully, we need to commit the changes that we made earlier

To make commit :


Hey! that’s all you need to do to read and insert the csv file into a database. Hope you enjoyed the tutorial….

After doing all the necessary steps successfully, you’ll get the data into your database as shown in the image below:
