Extract text from LINE bot projects (LBD)
To convert LBD projects to another format, you need LINE Bot Designer or other Developer software.
To convert other file formats to the "Prototyping Project Archive" file type, you need software like LINE Bot Designer or a similar tool.
The .LBD extension is most frequently associated with LINE Bot Designer, a prototyping tool used to visualize chatbots for the LINE messaging app. These files act as containers for conversation flows, rich menus, and message mockups. A major limitation for developers is that .LBD files are proprietary design projects, not deployable code. You cannot upload an .LBD file directly to the LINE Messaging API; it must first be parsed or exported. Furthermore, stakeholders without the specific designer software installed cannot view the conversation logic. To bridge the gap between design and development, users often need to convert these files to JSON to extract the raw message payloads or to ZIP to recover embedded image assets.
In scientific and laboratory settings, .LBD refers to a Spectral Library Database generated by Thermo Scientific OMNIC software. These binary files store collections of infrared (IR) or Raman spectra used for compound identification. The primary challenge here is significant vendor lock-in; these libraries are often inaccessible outside of the OMNIC ecosystem or specific Nicolet instruments. Researchers needing to analyze spectral data in Python, MATLAB, or Excel typically require conversion to CSV (text data), SPC (standard spectral format), or JDX (JCAMP-DX) for long-term archiving and interoperability.
Convert.Guru analyzes your LBD file, detects the exact format, and lets you read the text inside.
Users also converted LDB, FCA, FIB and GCF files.
If you want to convert LBD file to CSV, JSON, XML, YAML, YML, TOML, INI, CFG, CONF, DAT, DB or SQL, you can use LINE Bot Designer or similar software from the "Chatbot Design Project" 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 LBD, try LINE Bot Designer or another comparable tool in the "Chatbot Design Project" 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 LBD converter.
