Advanced Features

Extract Messages from Telegram Archive

You can extract messages from a Telegram export archive (result.json) that you've downloaded from Telegram Desktop:

# Extract all messages from all chats
telegram-download-chat "/path/to/Telegram Desktop/DataExport/result.json"

# Extract only messages from a specific user (by their Telegram ID)
telegram-download-chat "/path/to/Telegram Desktop/DataExport/result.json" --user 123456

# Save to a custom output file
telegram-download-chat "/path/to/Telegram Desktop/DataExport/result.json" -o my_exported_chats.json

This feature is particularly useful for:

• Processing your full Telegram data export
• Extracting specific conversations from the export
• Converting the export to a more readable format
• Filtering messages by user or date range (using --min-date or --last-days)

The tool will process the archive and generate both JSON and TXT files with the exported messages.

Resuming Interrupted Downloads

If the download is interrupted, you can simply run the same command again to resume from where it left off. The tool automatically saves progress to a temporary file. You can also resume later using --since-id with the last downloaded message ID or let the tool read it from the existing JSON file. Use --overwrite to replace existing output files instead of resuming.

User Mapping

Display names for users and bots are collected automatically. You can override them in the users_map section:

users_map:
  123456: "Alice Smith"
  789012: "Bob Johnson"

Chat Mapping

Titles for group and channel chats are fetched automatically. Use chats_map only if you want to override them:

chats_map:
  100123456: "MyGroup"

Keyword Filtering

Use --keywords to save only messages that contain at least one of the given words. This reduces output size when you need messages about specific topics.

• Behavior: After downloading (within your date/limit), messages are filtered; only those whose text contains at least one keyword (case-insensitive) are written to JSON and TXT.
• Format: Comma-separated list, e.g. --keywords "word1,word2,@user".
• Result: The summary (and --results-json) still includes a keywords block with counts and sample messages per keyword.

# Save only messages containing "после" or "hello"
telegram-download-chat username --min-date 2026-01-01 --keywords "после,hello"

Subchat Extraction

Extract conversations from specific threads or reply chains:

# Extract messages from a specific thread
telegram-download-chat group_username --subchat 12345 --subchat-name "Important Discussion"

# Or use a direct message URL
telegram-download-chat group_username --subchat "https://t.me/c/123456789/12345"

Graphical User Interface (GUI)

For users who prefer a visual interface, the application includes an optional GUI that provides an intuitive way to download Telegram chats.

Launching the GUI

# Launch the GUI application
telegram-download-chat --gui

The tool generates the following files for each chat:

• Message IDs and timestamps
• Sender information
