Development of a Python script for local export of Telegram channels (open/closed)

Budget: 2500 UAH Deadline: 3 days

Hello! I will create a local Python script using Telethon — extracting from all 4 sources: private channels, chat, group with Topics. What will be included: complete message history, reply chains linked by ID, correct distribution by topics, downloading media to local folders. Format — JSON + SQLite at your choice. No third-party servers — the script works only on your computer. I will provide the clean source code and a step-by-step guide for running it.

Hello, I worked on a script for exporting data from Telegram channels and groups for an analytical company - I extracted over 50K messages with media files, saved the entire structure of responses and metadata locally.

I wonder if it will be necessary to keep the history of message edits and deleted posts for the completeness of the archive?

I suggest we get in touch, I will consult you for free on the technical side and we will create a development plan + I will tell you about my team!

Hello! I can implement it. Please write to me in Private for discussing the details.

Budget: 1000 UAH Deadline: 1 day

Good day, I have experience working with Python as well as Telegram bots, I can complete everything quickly and efficiently, write to discuss the details.

Budget: 4000 UAH Deadline: 2 days

I understand the task. I will do it strictly locally: Python + Telethon (official MTProto API), no clouds, intermediaries, or SaaS. Data will only go to the hard drive.

What will be done:

Separate export of 2 channels, 1 chat, and 1 group with topics.

Preservation of reply chains: reply_to → message_id.

I will correctly organize topics into branches without mixing.

I will download media linked to the message ID.

Result: JSON + standalone HTML viewer.

Delivery: source code, requirements.txt, and instructions for running.

I am ready to start. Expand

Hello!

Telethon is a standard tool for such tasks, it works through the official Telegram API completely locally. Closed channels are unloaded if the account is a participant, Topics are supported, media is stored with a link to the message ID. I will provide the code and instructions for running it completely.

Feel free to reach out - I will be happy to collaborate!

Hello! I am Vladimir, the founder of the engineering agency Vaysed. Your requirement for absolute confidentiality and local data processing is an exceptionally prudent approach, especially when working with closed sources. We specialize in developing secure data collection architectures and are ready to implement this tool strictly according to your rules.

We will develop a standalone Python script based on the Telethon or Pyrogram library, which will interact directly with the official MTProto API of Telegram. No webhooks, cloud databases, or third-party SaaS solutions. The script will run exclusively in the terminal on your PC, authenticating as a regular user (via Userbot) to gain legitimate access to the specified channels and group.

Technically, the logic of the export will ensure a hundred percent preservation of the dialogue structure. To correctly process Topics (branches) in supergroups and track response chains, the script will use the parameters reply_to_msg_id and message.thread_id. All text and metadata (author, time, whom responded to) will be neatly organized into a structured local SQLite database or JSON files. Simultaneously, all media files (documents, photos, videos) will be downloaded into a separate directory on your hard drive with a strict naming convention tied to the ID of the specific message.

In the end, you will receive fully open, clean source code without any obfuscation. This will allow you to personally verify the complete absence of third-party network requests and leaks. Additionally, we will prepare a detailed step-by-step guide for setting up the Python virtual environment, installing dependencies, and safely running the tool.

The estimated implementation and testing will take 3 working days. You can assess our engineering approach to creating automation systems on our agency's website: https://vaysed.me/

I would be happy to discuss the approximate volume of media files to be exported in private messages and promptly start assembling this tool. Expand

Hello! The project perfectly matches my expertise. The tool for local backup via Telethon (official Telegram API) has already been conceptually developed.

Here’s how I will implement it:
1. Complete locality: No third-party servers. The script runs exclusively on your PC.
2. Structure and Topics: Data is stored in a reliable JSONL format (each line is a separate message). The full hierarchy of reply_to is preserved, and topic_id is correctly extracted for distribution across branches in groups.
3. Media: Files are downloaded into local folders named after the source, and the files themselves are linked to message.id for perfect synchronization with the text.

What you will receive:
— Clean source code in Python.
— A requirements.txt file for quick installation of libraries.
— A detailed text instruction for running.

I have extensive experience in writing automation. I can deliver the finished and tested software by tomorrow. Message me privately, I am ready to start right now. Expand

Hello! I am ready to implement a local Python script using Telethon to extract data from 4 Telegram sources: messages, media, metadata, replies, and Topics. The data is saved only on your disk, without third-party services. I will provide the source code and instructions for running it. Deadline: 2-4 days.

Budget: 3500 UAH Deadline: 2 days

I fully share your priority on confidentiality — implementing the tool exclusively as a local Python script is the most reliable solution. I will develop the software based on the Telethon library, which directly interacts with the official Telegram API without using third-party servers. The script will perform a deep extraction: correctly distributing messages by Topics, preserving the hierarchy of replies, and downloading media files directly to your hard drive while maintaining relationships. As a result, you will receive a structured database (JSON or SQLite) and an organized media archive ready for reading. Upon completion, I will provide the full source code and a step-by-step guide for setting up the environment on your PC. Please note that for the script to run 24/7 (if the history is very large and requires time to extract media), a stable connection may be required.

Ready to take it on.
Need to clarify the details of the order, write!
I use python, uv, github, docker.

Hello! The task is clear: an autonomous tool is needed for local data backup without leaking information to third-party servers.

I have experience developing similar parsers in Python (Telethon / Pyrogram). I will implement a script that will download the history, including media and the structure of Topics, through the official Telegram API (App API ID/Hash). To preserve the "reply-message" relationships and metadata, the best format would be JSON or a local SQLite database, which can then be easily converted into a readable Excel/HTML.

I guarantee complete locality: the script will only work with your API key, and the data will be stored in the specified folder on your disk. I will provide clean code and a brief instruction for setting up the environment (venv).

Please clarify:

What is the approximate volume of media expected (GB)?

Should comments on posts in channels be exported, or just the posts themselves? Expand
