Extract text from LEGO Mindstorms projects (LMSP)
To convert LMSP projects to another format, you need LEGO MINDSTORMS EV3 Classroom or other Developer software.
To convert other file formats to the "Scratch Block Program" file type, you need software like LEGO MINDSTORMS EV3 Classroom or a similar tool.
.LMSP files are project files created by LEGO MINDSTORMS EV3 Classroom, a robotics coding environment based on Scratch. They store block-based programming scripts, sounds, and images used to control EV3 robots. The main disadvantage of this format is its locked ecosystem. The LEGO Group officially retired the Mindstorms product line at the end of 2022, making the official software increasingly obsolete and difficult to install on modern operating systems. Furthermore, .LMSP files are not natively readable by web browsers or standard text editors. Because it relies heavily on proprietary hardware extension blocks, you cannot easily migrate the code to other robotics platforms.
Users typically need to convert or extract .LMSP files to recover their hard work, such as custom WAV audio recordings, SVG sprites, or the core logic from old projects. The best conversion workaround is treating the file as a ZIP archive to extract the internal media, or converting the logic to raw JSON. While it is technically a Scratch program, converting it directly to a standard SB3 file is problematic; standard Scratch does not recognize EV3 hardware commands, so hardware-specific blocks will appear as 'undefined'.
Because this is a closed, proprietary robotics format, standard online converters fail to process it into a working executable. Often, only the original EV3 software can properly deploy the data to a physical robot. However, you can bypass these limits. Just drag and drop your file into convert.guru to identify the format, view it, and convert it when possible. Our engine can unpack the internal ZIP structure, allowing you to instantly download the embedded sounds, images, and raw JSON code without needing the original LEGO software.
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.
If you want to convert LMSP file to TMP, TEMP, CACHE, LOG, BAK, OLD, NEW, PART, DOWNLOAD, CRDOWNLOAD, LOCK or PID, you can use LEGO MINDSTORMS EV3 Classroom or similar software from the "Robotics Project Programming" category. In the File menu, look for Save As… or Export….
To convert DEVICE, CACHE, SOCK, SYMLINK, PID, MOUNT, FIFO, LOG, PIPE, TMP, JUNCTION or TEMP files to LMSP, try LEGO MINDSTORMS EV3 Classroom or another comparable tool in the "Robotics Project Programming" 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 LMSP converter.
