About LMSP files

A .LMSP file is a project archive generated by the LEGO MINDSTORMS EV3 Classroom application. Under the hood, this is not a magical robot file; it is a standard ZIP container that holds a project.json file (defining the Scratch-based block code), along with SVG images and WAV audio files used by the robot. The primary problem for users is that .LMSP files are proprietary to the EV3 Classroom environment, which has replaced the older LabVIEW-based EV3 software but is itself subject to compatibility issues on newer operating systems (like macOS Ventura+). Because the format is opaque, you cannot easily view the code or assets without the specific educational software installed. For archiving or asset recovery, the most pragmatic conversion is often to ZIP, allowing you to extract the raw media and logic. If you need to document the code for a report, capturing screenshots within the LEGO software is often necessary, as direct conversion to PDF is not natively supported.

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

Users also converted EV3, IMSP, RBT and RXE files.

The LMSP 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 LMSP converter.
