About LLSP files

The .LLSP file is a robotics programming project created by the LEGO Education SPIKE application. It stores the logic, block-based code (Scratch), MicroPython scripts, and media assets used by students and developers to control SPIKE Prime and SPIKE Essential robotics hubs.

The format is natively managed by the LEGO Education SPIKE (Legacy/v2) software. However, the ecosystem is highly proprietary. A major real-world frustration for educators and developers is that the modern SPIKE v3 app transitioned to the newer .LLSP3 format, completely breaking backward compatibility with older .LLSP files. Furthermore, sharing an .LLSP file for code review or grading is incredibly tedious, as the recipient must install the massive, resource-heavy LEGO desktop application just to view the programming blocks.

The most practical conversion target for an .LLSP file is ZIP. Under the hood, an .LLSP is actually a standard compressed archive. Converting or extracting it yields the raw, unencrypted project assets - including an SB3 file containing the Scratch code, a JSON manifest, and SVG icons - with zero data loss.

Because this is a niche educational format, generic online converters will fail to process it. Just drag and drop your .LLSP file onto convert.guru to automatically identify its internal archive structure. We can safely bypass the LEGO software requirement, allowing you to instantly extract the internal components, view the raw Scratch code, and recover your trapped project data.

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.
