TDATA vs Session+JSON: Which Telegram Account Format Should You Buy?

When you buy Telegram accounts you'll be asked to choose a format: TDATA or Session+JSON. They're not interchangeable at a glance, and picking the wrong one slows you down. Here's the practical difference.

What is TDATA?

TDATA is the native session format used by Telegram Desktop. You drop the TDATA folder into the client's data directory — or load it into automation software that reads TDATA — and you're logged in immediately, with no SMS code. It's the fastest path to a working account on a real desktop client.

What is Session+JSON?

Session+JSON is built for programmatic control. The .session file holds the authorised login while the JSON carries device and API metadata, so libraries like Telethon and Pyrogram connect without a code prompt. Matching fingerprints in the JSON keep sessions stable and reduce early logouts.

Side-by-side

Use case	Best format
Telegram Desktop, manual use	TDATA
Multi-account warming on desktop	TDATA
Python bots and scrapers	Session+JSON
Distributed API automation	Session+JSON

Can you convert between them?

Yes. TDATA can be converted to Session+JSON and back with standard converter tools, so a format mix-up is usually fixable on your side. Still, buying the right format saves a step.
