Aseprite Script - Split Sprites Into Layers

🎯 Script: Split Sprites Into Layers

This tool turns a flat PNG sprite sheet into a clean, fully structured Aseprite file — with real groups, numbered layers, and everything ready to go.

🛠️ What exactly does it do?

• Run the script
• Enter the new file name
• Choose how your sheet is laid out: Horizontal Strip, Vertical Strip, By Rows or By Columns
• Set tile size and how many tiles per group
• Click “Import” — done!

It instantly creates a new file with all your tiles neatly sliced, grouped (Group 1, Group 2, etc.), and layers named 1, 2, 3… inside each group.

✨ What’s it for?

This script is ideal for:

• Organizing sprite sheets fast, without slicing manually
• Modular assets, breaking up characters, UI, props or animations
• Game dev pipelines, structuring files for team collaboration
• Animators, turning big flat sheets into layered frame-ready sets
• Artists who want to keep their work clean and organized from the start

💬 If you want to customize it more, I can help you or you can easily adapt it. 

🚀 This is one of those little scripts that save you hours if you work with a lot of files. Do you already know what you are going to use it for?
