Convert LLSP to ZIP

QUICK ANSWER
Is it possible to convert LLSP to ZIP?
Yes - LLSP converts to ZIP.

An .llsp file is a ZIP container in disguise, so the fastest path is to copy the file and change its extension to .zip, then open it with any archiver. No real conversion or re-encoding happens - you are just exposing the ZIP that was always there.

Why convert LLSP to ZIP?

People rename an .llsp to .zip to peek inside a SPIKE Prime project and pull out the program blocks, icon, and manifest that the app stores as separate files. Because the SPIKE app writes projects in ZIP format, treating it as a .zip gives you plain access to those contents without any special tool.

How to convert LLSP to ZIP

7-Zip FREE

Right-click the .llsp file and choose 7-Zip > Open archive, or run 7z x myproject.llsp to extract its contents directly without renaming.

unzip (command line) FREE

Run unzip myproject.llsp -d out/ to unpack the project into a folder. The unzip tool ignores the .llsp extension and reads the ZIP structure directly.

The Unarchiver FREE

Open the .llsp with The Unarchiver (or Archive Utility) to extract it as a folder. It auto-detects the ZIP format regardless of the .llsp name.

About these formats

Quality & what to watch

  • Nothing is converted or recompressed - you are only relabeling or extracting an existing ZIP, so the bytes are identical.
  • The files inside (like manifest.json and the program data) are SPIKE-specific and only meaningful to the LEGO app, not to general software.
  • Renaming a .zip back to .llsp restores it, but editing the inner files by hand can corrupt the project so the SPIKE app refuses to open it.

Frequently asked questions

Is an .llsp file really just a ZIP?
Yes. LEGO Education SPIKE Prime saves projects using the ZIP format, so an .llsp opens with any ZIP tool once you rename or extract it.
Will renaming .llsp to .zip damage the project?
No, renaming a copy is non-destructive. Keep the original .llsp intact and work on the .zip copy.
What's inside the ZIP?
You'll typically find the program blocks or Python code, a manifest.json describing the project, and an icon or thumbnail image.
Can I edit the files and repack them?
You can, but the SPIKE app validates the structure. Hand-editing often breaks the manifest and the app may then reject the file.
