Extract text from Session files (SESSION)
To convert SESSION Sessions to another format, you need Telethon or other Database software.
To convert other file formats to the "Application State Database" file type, you need software like Telethon or a similar tool.
The .session file extension is primarily used to store application state data, but its internal format depends entirely on the software that created it. Most commonly, it acts as a SQLite database used by the Telethon library for Telegram. In this context, it stores authentication keys, server details, and active connection states. Alternatively, Apple iOS generates .session files formatted as plain text JSON to log system analytics and diagnostic data. Other applications, like Serato DJ Pro, Facebook (using plist structure), tmux, and CATIA 4, also use this extension to save user sessions, restore workspaces, or back up history.
Users often need to convert .session files because the format is strictly designed for internal software use, not for human reading. Telethon databases are binary SQLite files that cannot be opened in standard text editors without showing corrupted characters. Apple iOS logs are technically JSON but lack the standard JSON extension, confusing basic viewers. Furthermore, proprietary variants like Serato DJ histories or CATIA 4 sessions are closed formats that trap user data inside expensive or highly specific software ecosystems.
If you need to extract data, the best target formats depend on the underlying structure. Telethon .session files should be exported to CSV or SQL to read database tables. Apple iOS or tmux logs can simply be converted to TXT or JSON. For proprietary variants, conversion is notoriously difficult because standard online converters fail when they see the ambiguous .session extension and cannot guess the internal structure. Our platform inspects the raw file headers. If our analysis detects an underlying SQLite database, JSON text, or plist XML embedded inside, we can extract the text or convert it to a standard, accessible format.
Convert.Guru analyzes your SESSION file, detects the exact format, and lets you read the text inside.
Users also converted IPS, SYNCED, SES, PHAR, PO and PHP files.
If you want to convert SESSION file to OBJ, FBX, DAE, 3DS, MAX, BLEND, MA, MB, C4D, STL, PLY or WRL, you can use Telethon or similar software from the "Application State Data Storage" category. In the File menu, look for Save As… or Export….
To convert DWG, DAE, X3D, IGES, WRL, JT, SKP, 3DS, 3DM, OBJ, STEP or FBX files to SESSION, try Telethon or another comparable tool in the "Application State Data Storage" category.
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our SESSION converter.
