Context Merger

Context Merger is a Visual Studio Code extension that helps you quickly merge multiple files and folders into a single, well-structured text file. It's perfect for:

• Sharing project context with LLMs (ChatGPT, Claude, Gemini, Copilot)
• Code reviews
• Documentation
• Debugging sessions

Instead of manually opening, copying, and pasting files, Context Merger lets you right-click any selection in the VS Code Explorer and instantly generate a unified file containing all relevant source code, organized and ready to use.

Features

• Merge multiple files and folders into a single Markdown file
• Automatically adds file headers and preserves folder structure
• Ignores common unwanted directories: node_modules, .git, dist, build, .next, out
• Shows total files, character count, and estimated tokens (useful for LLM input limits)
• Supports any file type

Demo

Usage

1. Select one or more files/folders in the VS Code Explorer.
2. Right-click and choose Merge into Single File.
3. A new Markdown file opens with all selected content merged.
4. A summary shows total files, total characters, and estimated token count.

Example Output

## myProject/src/index.ts
```text
console.log("Hello World");
```

## myProject/src/utils/helpers.ts

```text
export function add(a, b) {
  return a + b;
}
```
