Extract text from 8XK files
To convert your 8XK file to another format, you need TI Connect or other Executable software.
To convert other file formats to the "Calculator Flash App" file type, you need software like TI Connect or a similar tool.
A .8XK file is a compiled Flash Application designed for Texas Instruments graphing calculators, specifically the TI-83 Plus and TI-84 Plus series. Unlike standard programs (.8xp) which run from temporary RAM, these files are installed into the calculator's non-volatile Flash ROM, allowing them to persist even when the battery is removed. Users typically encounter these files when downloading third-party math utilities, science tools, or games (like MirageOS) from community archives.
A major limitation is that .8XK files are binary blobs containing Z80 assembly code; they cannot be opened or executed directly on a Windows or macOS desktop. They require specialized "linking" software to transfer them to a physical device or an emulator to run them virtually. Because they are compiled for a specific proprietary processor, converting them to standard formats like PDF or DOCX is technically impossible and functionally useless. However, developers may want to "convert" them to a Hex Dump or Disassembled Text to analyze the source code.
For most users, the goal is not conversion but emulation or transfer. To view the content, use an emulator like Wabbitemu or CEmu. To move the file to a calculator, use TI Connect or the open-source TILP.
Convert.Guru analyzes your 8XK file, detects the exact format, and lets you read the text inside.
Users also converted ZIP, TXT, 8XP, 8XG and 8XL files.
If you want to convert 8XK file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use TI Connect or similar software from the "Graphing Calculator Application" category. In the File menu, look for Save As… or Export….
To convert DBF, XML, SQLITE, XLSX, SQL, TSV, ACCDB, YAML, MDB, CSV, ODS or JSON files to 8XK, try TI Connect or another comparable tool in the "Graphing Calculator Application" 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 8XK converter.
