Telegram Session, JSON and TData: format differences and conversion logic

SEO guide for responsible Telegram data migration, account format conversion and converter workflow planning.

Telegram Session, JSON and TData: format differences and conversion logic is written for teams that need a clear and responsible explanation of Telegram data formats. The goal is not to mix archives, working sessions and Desktop folders, because each layer solves a different task.

Why the format matters

Telegram-related workflows can involve Session files, Session+JSON profiles, TData folders, AuthKey data and mobile source files. A reliable Telegram converter should preserve the logic of the route instead of simply renaming files.

Before any conversion, create a backup, verify the source format, check the expected output and keep the process limited to accounts and data you are authorized to manage.

Responsible migration

Safe migration means controlled storage, a clean folder structure, access protection and a test run before batch processing. This approach reduces failed conversions and makes logs easier to understand.

Checklist

• Identify the source format.
• Choose the required output: Session, Session+JSON or TData.
• Keep an untouched backup.
• Check language, DC, device and 2FA-related context.
• Run a small test before a large batch.

Choosing a converter

HC2S is used for AuthKey/HEX:DC routes, STSJ for Session to Session+JSON, S2TD for Session to TData, TD2S for TData to Session, and MTCR for Telegram mobile files.
