Telegram URL Fetcher

This Python script extracts URLs from messages in a specified Telegram channel and writes the URLs into an Excel file.

Requirements

To run the script, you will need the following:

  • Python 3.x
  • A Telegram account
  • Telegram API credentials (API ID and API hash)
  • The following Python libraries:
    • telethon
    • pandas
    • openpyxl
    • re (part of the Python Standard Library)

Setup

1. Install Python Packages

Before running the script, make sure to install the required packages. You can do so by running the following commands:

pip install telethon pandas openpyxl

2. Telegram API Setup

  1. Go to my.telegram.org and log in with your Telegram account.
  2. Create a new application under the "API development tools" section.
  3. You will receive your API ID and API hash. Keep these credentials safe as you'll need them to run the script.

3. Script Configuration

In the script, replace the placeholder values with your actual API credentials and phone number:

api_id = 'YOUR_API_ID'  # Replace with your API ID
api_hash = 'YOUR_API_HASH'  # Replace with your API hash
phone = 'YOUR_PHONE_NUMBER'  # Replace with your phone number

Also, specify the channel name from which you want to extract URLs:

channel_name = 'your_channel_name'  # Replace with the channel's username or ID

4. Running the Script

Once you've set up your environment, you can run the script by executing the following command in your terminal:

python fetch.py

5. Script Flow

  1. The script connects to Telegram using the telethon library.
  2. It fetches a specified number of messages from a channel.
  3. Using a regular expression, it extracts all URLs found in the messages.
  4. The extracted URLs, along with message metadata (Message ID, Date, Sender ID), are saved into an Excel file (telegram_urls.xlsx).

Script Breakdown

  • fetch_urls_from_messages: This function fetches messages from a specified Telegram channel and extracts URLs using a regular expression.
  • write_to_excel: This function writes the extracted URLs and message metadata into an Excel file.

Example Output

The Excel file (telegram_urls.xlsx) will have the following columns:

  • Message ID: The unique ID of the message where the URL was found.
  • Date: The timestamp of the message.
  • Sender ID: The ID of the sender who sent the message.
  • URL: The URL extracted from the message.

Limitations

  • The script fetches up to a specified limit of messages (default is 100). You can change this limit by modifying the limit argument in the fetch_urls_from_messages function.
  • The script assumes the channel is public or you have access to the channel via your Telegram account.
