Extract text from OneTouch data files (TCH)
To convert TCH Data files to another format, you need OneTouch Reveal or other Data software.
To convert other file formats to the "Proprietary Data Container" file type, you need software like OneTouch Reveal or a similar tool.
The .tch file extension represents several distinct proprietary formats. Most commonly, it is an encrypted blood glucose data file generated by LifeScan OneTouch glucose meters. Alternatively, it functions as a texture file for the Creative Assembly Warscape Engine (used in the Total War game series), an embroidery thread chart encoded in UTF-16 (LE) for Wilcom Hatch, or a hash database file managed by the Tokyo Cabinet library.
The main disadvantage of .tch files is their highly restrictive, closed nature. OneTouch medical data is AES-encrypted to comply with privacy standards, meaning it cannot be opened or parsed without the official LifeScan software. Similarly, Warscape Engine textures are compiled game assets requiring specialized modding community tools to extract. Standard viewers, database readers, and standard online converters consistently fail to process these files because they lack the specific decryption keys or structural algorithms required to decode the binary data.
To safely convert a .tch file, your target format depends entirely on its source. Encrypted medical data must typically be synced through official apps and exported to standard CSV or PDF reports for healthcare providers. Game textures can sometimes be extracted to standard DDS or PNG files using modding utilities. Wilcom thread charts, being plain UTF-16 text, can be read as TXT.
Because these formats are heavily specialized, universal converters usually struggle.
Convert.Guru analyzes your TCH file, detects the exact format, and lets you read the text inside.

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 TCH converter.
