Open ICS File

Information, tips and instructions


The ICS format is widely used for sharing calendar events across a multitude of applications and platforms. On the other hand, CSV (Comma Separated Values) is a straightforward and universal format for tabular data, often exported and imported into spreadsheets, databases, and various other applications. This article aims to guide you through the process of converting a CSV file to an ICS format, either directly or by using a Python script, with the help of ChatGPT.

Let's first clarify a crucial point. The CSV format can have a vast range of structures, as there's no absolute standard. So, before we begin, it is vital to specify the CSV structure or provide an example of your CSV file.

Direct Conversion using ChatGPT

First, we'll cover how you can directly converse with ChatGPT to convert CSV data into ICS format.

Assume you have a CSV file that consists of the following fields: "Event Name", "Start Date", "End Date", and "Location". An example of this format could be:

Event Name,Start Date,End Date,Location
Annual Meeting,2023-06-15,2023-06-15,New York
Team Outing,2023-07-20,2023-07-22,Boston

You can input this CSV data to ChatGPT and request it to convert into ICS format:

ChatGPT, please convert this CSV data into an ICS format:

Event Name,Start Date,End Date,Location
Annual Meeting,2023-06-15,2023-06-15,New York
Team Outing,2023-07-20,2023-07-22,Boston

Based on this request, ChatGPT might respond with something like:

PRODID:-//Your Company//NONSGML v1.0//EN

UID:[email protected]
SUMMARY:Annual Meeting

UID:[email protected]
SUMMARY:Team Outing


This output is an ICS file format that is compatible with various calendar applications like Google Calendar, Apple Calendar, and Microsoft Outlook.

Generating a Python Script using ChatGPT

If you have a larger CSV file, or you want to automate the process, you can ask ChatGPT to help you write a Python script. The script will be based on the CSV structure you provide. Continuing with the same CSV structure as above, you might ask:

ChatGPT, could you please provide a Python script to 
convert a CSV file with the format: 
"Event Name,Start Date,End Date,Location" into an ICS file?

ChatGPT could then provide a Python script like the following:

import csv
from ics import Calendar, Event
from datetime import datetime

# Define the CSV file location
csv_file = 'path_to_your_file.csv'

# Create a new calendar
cal = Calendar()

# Read the CSV file
with open(csv_file, 'r') as file:
    reader = csv.reader(file)
