About TEL files

The .TEL file extension is a highly fragmented data format used across multiple distinct industries. Its most common use is storing train event recorder data for HaslerRail locomotive black boxes. However, it is also widely encountered as a SIM card phonebook backup created by legacy mobile phones, or as telemetry data for the FlightGear flight simulator. Other obscure uses include structural analysis models in S-FRAME, Italian tax return files from Agenzia delle Entrate, Telugu language text documents, and Zuken CADSTAR netlists.

Because multiple unrelated systems share the .TEL extension, users face significant challenges when trying to open them. A .TEL file from a train data recorder is proprietary binary data requiring expensive industrial software like TEL Viewer. A .TEL phonebook backup is effectively useless on modern smartphones. You cannot simply double-click these files, and they are completely unsupported by modern web browsers or standard office suites.

To make this data usable, conversion is mandatory. For legacy phone contacts, convert .TEL to VCF (vCard) to seamlessly import them into modern Android or iOS devices, or to CSV for bulk editing in Microsoft Excel. For text-based telemetry, Italian tax forms, or script documents, convert to TXT or PDF for easy archiving and readability.

Convert.Guru analyzes your TEL file, detects the exact format, and lets you read the text inside.

Users also converted TFT, MLF and AT2 files.
