How to Vs Code Compare Two Files Using the Built-in Diff Tool

Method 1: Compare Two Opened Files

This is the simplest and most common method:

1. Open both files you want to compare in VS Code.
2. Right-click the first file tab → select “Select for Compare”.
3. Switch to the second file → right-click → choose “Compare with Selected”.

A comparison view will open, showing both files side-by-side with highlighted differences.

Method 2: Compare Two Files from the Explorer Panel

1. In the file explorer, right-click File A → Select for Compare.
2. Right-click File B → Compare with Selected.

Method 3: Use Keyboard Shortcuts

While there isn’t a default shortcut to compare directly, you can streamline the process using the Command Palette:

1. Press Ctrl + Shift + P (Windows/Linux) or Cmd + Shift + P (Mac).
2. Type: Compare
3. Select commands like:
   • “File: Select for Compare”
   • “File: Compare with Selected”

Understanding the VS Code Diff View

• Left side = Original file
• Right side = Modified file
• Colored change indicators:
  • Red – Removed content
  • Green – Added content
  • Blue/Yellow – Modified content
• Sync scroll to compare matching lines
• Mini-map showing change locations

Developers can copy content between panels to merge changes manually when needed.

VS Code allows comparing content even if it’s not saved as a file:

1. Copy text to clipboard.
2. Create new file → paste clipboard content → Select for Compare.
3. Compare with another file using the same steps as above.

This is particularly useful for content editors analyzing SEO modifications or testing formatting updates before publishing.

Using the diff view helps you prevent accidental duplicate content or deletion of important ranking signals during updates.

Actionable SEO Checklist for File Comparisons

When comparing content updates in VS Code, review:

Technical SEO

• Ensure canonical and meta tags remain intact.
