About LLSP files

The .LLSP file extension is exclusively associated with the LEGO Education SPIKE Prime system, a learning platform that combines colorful LEGO building elements with easy-to-use hardware and coding language based on Scratch and Python. These files serve as project containers that store the program logic, sound assets, and configuration settings required to operate the SPIKE Prime Hub.

While excellent for classroom environments, the .LLSP format presents significant friction for advanced users and archivists. It is a proprietary container that typically requires the bulky LEGO Education SPIKE App just to view the code. This creates a "black box" effect where the underlying logic is inaccessible without specific software, making version control (like Git) or quick code reviews on mobile devices nearly impossible. Furthermore, compatibility issues can arise between different versions of the LEGO software.

Technically, an .LLSP file is simply a ZIP archive in disguise. For users looking to extract their code or backup assets, the most practical workflow is converting the file to a standard ZIP. This allows you to unzip the contents and access the internal project.json or, if you are using text-based coding, the raw PY (Python) script. For documentation purposes, converting the internal code logic to PDF or TXT is recommended for sharing without requiring the recipient to install the LEGO environment.

Convert.Guru analyzes your LLSP file, detects the exact format, and lets you read the text inside.

Users also converted LLSP3, LISP, LSP, JSON, SB3, ADP, PZF and NPF files.

The LLSP Converter Story

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 LLSP converter.
