Extract text from BYKI flashcards (B4U)

To convert other file formats to the "Flashcard List" file type, you need software like Byki Deluxe or a similar tool.
A .B4U file is a proprietary data format associated with the legacy BYKI (Before You Know It) language learning software developed by Transparent Language. These files function as digital flashcard decks, storing vocabulary lists, phrase pairs, and references to associated audio pronunciation files.
The primary challenge with .B4U files is their proprietary nature; they are designed exclusively for the Byki Deluxe or Byki Express desktop applications, which are largely obsolete and difficult to run on modern operating systems like Windows 11 or macOS. Because the format is not human-readable plain text, users cannot simply open it in Microsoft Word or a standard text editor to retrieve their study data. This creates a significant "lock-in" problem for learners who want to migrate their vocabulary lists to modern spaced-repetition platforms.
To salvage this data, the best workflow is to convert the .B4U file into a structured open format. For importing into apps like Anki, Quizlet, or Memrise, converting to CSV (Comma Separated Values) or TXT (Tab Delimited) is ideal. For general archiving or editing, converting to XLSX allows you to manage the word lists in Microsoft Excel.
Convert.Guru analyzes your B4U 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 B4U converter.
