Notebook Cell Index

Shows sequential cell numbers (Cell 1, Cell 2, ...) in the status bar of notebook code cells in VS Code.

Features

• Displays Cell N labels on code cells in any notebook type
• Only numbers code cells (markdown cells are skipped)
• Numbers update automatically when cells are added, removed, or reordered

How It Works

Each code cell gets a left-aligned status bar item showing its position among code cells. Markdown cells are excluded from the count.

Requirements

• VS Code 1.56 or later
• Any notebook open in the editor
