Convert CSV to HTML Table using Python Pandas and Flask Framework
In this article, we are going to convert a CSV file into an HTML table using Python Pandas and Flask Framework.
Sample CSV file :
USERNAME,IDENTIFIER,FIRST_NAME,LAST_NAME booker12,9012,Rachel,Booker grey07,2070,Laura,Grey johnson81,4081,Craig,Johnson jenkins46,9346,Mary,Jenkins smith79,5079,Jamie,Smith
Stepwise Implementation
Creating Environment
Step 1: Create an environment. Create a project folder and a venv folder within.
py -3 -m venv venv
Step 2: Activate the environment.
venv\Scripts\activate
Step 3: Install Flask and Pandas.
pip install Flask
pip install pandas
Creating Project
Step 1: Create ‘app.py’ folder and write the code given below.
Python3
# importing flaskfrom flask import Flask, render_template # importing pandas moduleimport pandas as pd app = Flask(__name__) # reading the data in the csv filedf = pd.read_csv('sample_data.csv')df.to_csv('sample_data.csv', index=None) # route to html page - "table"@app.route('/')@app.route('/table')def table(): # converting csv to html data = pd.read_csv('sample_data.csv') return render_template('table.html', tables=[data.to_html()], titles=['']) if __name__ == "__main__": app.run(host="localhost", port=int("5000")) |
Step 2: Create the folder ‘templates’. create the file ‘table.html’ inside the ‘templates’ folder.
HTML
<!DOCTYPE html><html lang="en"> <head> <title> Table </title> </head> <body> <div align="center"> <table> <h1> <!--Displaying the converted table--> {% for table in tables %} <h2>{{titles[loop.index]}}</h2> {{ table|safe }} {% endfor %} </h1> </table> </div> </body></html> |
Step 3: Add the ‘sample_data.csv’ file.
Step 4: The project structure will look like this.
Structure of the project
Run the Project
Step 1: Run the server.
Step 2: Browse the URL ‘localhost:5000’.
Step 3: The output web page will be displayed.
Output:
Output : CSV to HTML Table
