splitSelectionToLayers.jsx by Merista Lab

This repository contains the source code for the Illustrator script “Selection to Layer”.

---

Overview

splitSelectionToLayers.jsx is a utility script for Adobe Illustrator that automatically distributes selected objects into individual top-level layers.

• Single selection → one new layer
• Multiple selections → one new layer per object
• Layer names are applied only when the object has a user-defined name
• Illustrator’s auto-generated names (e.g., “Path”, “パス”) are ignored
• Reverse-order processing preserves the correct stacking order

Features

• Lightweight and simple
• Fully compatible with Illustrator's layer behavior
• Extendable structure for AE / PS automation
• ES3 / ExtendScript compliant
• Can be exported as JSXBIN (ideal for BOOTH distribution)
