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
• Filters to common code/document file types by default
• Optionally include any file type via a setting toggle
• Add custom extra file extensions to include
• Configurable ignored file/folder names (defaults include node_modules, .git, dist, build, .next, out)
• Optional cleanup for extra blank lines
• Optional comment stripping before merge
• Shows total files, character count, and estimated tokens (useful for LLM input limits)

Demo

Settings

• contextMerger.disableFileTypeFiltering (boolean, default: false)
  • When enabled, includes all file types.
• contextMerger.additionalFileTypes (string array, default: [])
  • Extra extensions to include in addition to built-in common code types (for example: .svg, .proto).
• contextMerger.ignoredFilesFolders (string array)
  • File/folder names to skip during traversal.
• contextMerger.skipExtraBlankLines (boolean, default: true)
  • Collapses extra blank lines in merged output.
• contextMerger.removeComments (boolean, default: true)
  • Removes comments from file contents before merge.

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
