.csv to HTML Converter

This is a really simple but effective way to convert single column .csv files to HTML files.


Why would you use this? Well sometimes you may have a long list you want to render as a table on a website. It can be very time consuming to do this by hand, so this script does it automaticaly in the blink of an eye. I used it on this post to render the list of voices as a table.


There are no prerequisites to install with this script.

How to use it

  1. Save the script below in the folder of your choice
  2. Rename the .csv file you want to convert as “input.csv” and save it in the same folder as the script
  3. Run the script
  4. The HTML file is saved as “output.html”
  5. If you want more than 2 columns, change “2” in the two places in the script indicated by comments
import csv

def csv_to_html(input_csv, output_html):
    with open(input_csv, 'r') as file:
        reader = csv.reader(file)
        data = [row[0] for row in reader]

    html_table = '<table>\n'
    for i in range(0, len(data), 2): # Change "2" to the number of columns you require
        html_table += '<tr>\n'
        for j in range(2):  # Change "2" to the number of columns you require
            if i + j < len(data):
                html_table += f'<td>{data[i + j]}</td>'
                html_table += '<td></td>'  # Add empty cell if data is exhausted
        html_table += '</tr>\n'
    html_table += '</table>'

    with open(output_html, 'w') as output_file:

if __name__ == "__main__":
    input_csv_file = "input.csv"
    output_html_file = "output.html"
    csv_to_html(input_csv_file, output_html_file)
