GroIMP includes a built-in text editor for editing source code and text files directly within the environment. When a file—such as a script or text document—is selected from the File Explorer, it automatically opens in this editor.

The editor supports standard editing operations, including:

• Cut & Paste
• Undo / Redo
• Save

This integrated editor allows users to conveniently write and modify XL code or other text-based content without needing external software. For some file types, additional actions are triggered when a file of that type is saved. For example, source code is compiled immediately.
