Initial Scraping Behavior 🕒

When scraping a channel for the first time, please note:

• The script will attempt to retrieve the entire channel history, starting from the oldest messages
• Initial scraping can take several minutes or even hours, depending on:
• The total number of messages in the channel
• Whether media downloading is enabled
• The size and number of media files
• Your internet connection speed
• Telegram’s rate limiting
• The script uses pagination and maintains state, so if interrupted, it can resume from where it left off
• Progress percentage is displayed in real-time to track the scraping status
• Messages are stored in the database as they are scraped, so you can start analyzing available data even before the scraping is complete

Usage 📝

The script provides an interactive menu with the following options:

• [A] Add new channel
• Enter the channel ID or channelname
• [R] Remove channel
• Remove a channel from scraping list
• [S] Scrape all channels
• One-time scraping of all configured channels
• [M] Toggle media scraping
• Enable/disable downloading of media files
• [C] Continuous scraping
• Real-time monitoring of channels for new messages
• [E] Export data
• Export to JSON and CSV formats
• [V] View saved channels
• List all saved channels
• [L] List account channels
• List all channels with ID:s for account
• [Q] Quit

Channel IDs 📢

You can use either: – Channel username (e.g., channelname) – Channel ID (e.g., -1001234567890)

Data Storage 💾

Database Structure

Data is stored in SQLite databases, one per channel: – Location: ./channelname/channelname.db – Table: messages – id: Primary key – message_id: Telegram message ID – date: Message timestamp – sender_id: Sender’s Telegram ID – first_name: Sender’s first name – last_name: Sender’s last name – username: Sender’s username – message: Message text – media_type: Type of media (if any) – media_path: Local path to downloaded media – reply_to: ID of replied message (if any)

Media Storage 📁

Media files are stored in: – Location: ./channelname/media/ – Files are named using message ID or original filename

Exported Data 📊

Data can be exported in two formats: 1. CSV: ./channelname/channelname.csv – Human-readable spreadsheet format – Easy to import into Excel/Google Sheets

1. JSON: ./channelname/channelname.json
2. Structured data format
3. Ideal for programmatic processing
