Project Data: An LLSP file contains code, images, configurations, and other assets necessary to run a LEGO SPIKE Prime project.

Primary Software: They are meant to be opened and managed with LEGO Education SPIKE Prime software. For more details, visit the LEGO Education webpage.

Usage: The files bundle all elements of a robotics project into one package, ensuring that projects are easy to share and manage.

Programs that open and convert LLSP files:

LEGO Education SPIKE Prime
See the previous paragraphs to learn more about the main application. LLSP files are often referred to as LEGO Education SPIKE Prime compresseds because this type of file is primarily created or used by this software.
LEGO® Education SPIKE™ Prime
A .LLSP file is a container file, essentially a ZIP archive, storing a LEGO® Education SPIKE™ Prime project. These projects encompass programs, models, and other supporting documentation created within the SPIKE™ Prime app. The SPIKE™ Prime software suite facilitates hands-on learning experiences in coding, robotics, and engineering for students. The .LLSP file acts as a convenient way to share, backup, and distribute these projects, enabling collaboration and portability of student work. Inside the archive, you'll find various files defining the project's components, including program code, model configurations, and potentially multimedia assets. This file format is classified as Compressed archive.

LLSP file format:

To find out what program is needed to open LLSP files, you need to determine the file format. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. Below is our analysis of the LLSP files:

LLSP is rarely used as a file extension and is mainly used by one program with a specific format. But the following two file formats are common:

96% of all LLSP files are based on the zip format, so multiple files are compressed and stored together in one LLSP file. Most often they are 3 to 4 compressed files. File names inside are icon.svg, manifest.json and scratch.sb3. A little tip: If you rename the file extension to .zip and then double-click, you will see the included files and images. Most of these files are 2 KB to 68 KB in size. The files contain the following words: manifest. The file name SwirlBot Demo V1.llsp is characteristic of these files. Files like these have the following tags: spike, instruction, legospike, demo, swirl, robot, code, balancer and prime.

All the rest of the LLSP files (4%) have different formats. The category is program, project, sorter or table. You can get all the details of your LLSP file by dragging it onto this page or by clicking the button "Choose your .llsp file to analyze" above.
