Script to export members Telegram Groups and Channels to a CSV file and to add members to Telegram Groups or Channels.

Exporting and adding members to channels requires the user from which the script is launched to be a Channel admin.

Install dependencies

This script requires telethon ( github ) to run.

You'd need python3 and pip3 installed and available in your PATH.

Run pip3 install -r requirements.txt from the projects root directory.

Telegram Configuration

1. To run it you need to generate API credentials for your Telegram user, you can do it here, and access your already created ones here

2. Copy the example credentials file - credentials.example.json to credentials.json

   The filename has to be exactly credentials.json because the name is hard-coded into the script.

3. Add the credentials obtained in Step 1 to credentials.json

Running the Script

The script is mostly interactive. It can be started in the most basic form :

python3 telethon-bot-add-users-to-groups.py

The script has 3 main features :

• Export users from group
• Add users to group
• print CSV

Export users

The export feature writes a comma-separated values (CSV) file with the filename of the form <group-name>-members.csv. The CSV can then later be used as an input file to the add users or print CSV features.

Add users to groups

Users can be added using:

• Username: Gets temporarily banned with less requests.
• User ID: Gets temporarily banned with more requests.

Temporary restrictions may last for up to a day.

The script expects a CSV file with input values ( one per line ).

The CSV file MUST have a header with at least one of the following fields

• username for adding by username
• user id for adding by user ID

Header values are compatible with the CSV that is generated with the same script.

Note : The values for the header is hard-coded in the application and is case-sensitive. The values must be in lower-case only

Auto-detect add mode

The script is capable of auto-detecting the add mode if the CSV file has only one column and the header is appropriately named as mentioned above

Resume capability

The script can also smartly resume from a certain offset point. This is useful when resuming operation after a cooldown period of a PeerFloodError. The script prints the command after handling a PeerFloodError. It looks similar to :

python3 telethon-bot-add-users-to-groups.py members.csv 1234567890 1 50

where the arguments correspond to :

argv[1] => input_file      | input CSV file
argv[2] => target_group.id | ID of group to add users
argv[3] => add_mode        | add by [1]. username or [2]. user ID
argv[4] => start_index     | offset to restart adding users

While the script is interactive by default, using this argument structure can trigger a non-interactive automatic add mode with the given parameters.
