Extract text from Apabi or data files (XDF)
To convert XDF files to another format, you need Apabi Reader or other E-Book software.
To convert other file formats to the "Protected E-Book Document" file type, you need software like Apabi Reader or a similar tool.
The .xdf file extension primarily represents either a protected e-book used by Founder Apabi Reader or an Extensible Data Format file for the Lab Streaming Layer (LSL). Apabi e-books are widely used for Chinese academic and commercial texts. Alternatively, LSL .xdf files store multi-channel physiological time-series data (such as EEG recordings) in a highly compressed binary container. A smaller percentage of .xdf files function as Engine Control Unit (ECU) definition files in tuning software like TunerPro RT or WinOLS, or as Microsoft Machine Learning Server data.
Working with .xdf files is notoriously frustrating because the format is heavily fragmented across unrelated industries. Apabi e-books are severely restricted by DRM, making them impossible to read on standard e-readers like Kindle or iPad without legacy software. They are proprietary and basically useless on modern systems. LSL data files are complex and cannot be viewed without programming knowledge in Python or MATLAB. TunerPro ECU files are technically raw XML, but they require specific automotive software to parse visually.
To make these files usable, conversion is mandatory. For e-books, convert .xdf to PDF or EPUB to ensure you can actually read the text on modern devices. For LSL scientific data, converting to CSV or JSON makes the data accessible in spreadsheet tools like Microsoft Excel. For ECU definitions, standard XML or TXT conversions allow for quick manual code edits.
Convert.Guru analyzes your XDF file, detects the exact format, and lets you read the text inside.
Users also converted DXF, PDF, XDFX, XFDF, XCF, XFD, XDW, ZIP, BIN, FDF, TXT, XAPK and JPG files.
If you want to convert XDF file to PDF, CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT or DB, you can use Apabi Reader or similar software from the "E-Book and Data Storage" 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 XDF, try Apabi Reader or another comparable tool in the "E-Book and 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 XDF converter.
