Diff Tips
  • Line-level diff: Best for code comparison and version control
  • Word-level diff: Ideal for documents and prose comparison
  • Character-level diff: Useful for exact text comparison
  • Ignore whitespace: Reduces noise from formatting changes
  • Use patches: Apply changes from one version to another

About Diff Checker

About Diff Checker

Our Diff Checker is a powerful tool for comparing text, code, JSON, and files to identify differences between two versions. It uses advanced diff algorithms to highlight additions, deletions, and modifications with precision.

The tool provides multiple viewing modes including side-by-side comparison, unified view, and patch generation. It supports various diff algorithms, customizable comparison options, and detailed statistical analysis of changes.

Perfect for developers comparing code versions, writers tracking document changes, system administrators analyzing configuration files, and anyone needing to identify differences between text versions. All processing happens client-side for privacy and speed.

How to Use

  1. Select comparison type: Text, Code, or JSON based on your content.
  2. Enter original text in the first field and modified text in the second field.
  3. Optionally upload files using the file upload buttons for file comparison.
  4. Configure comparison options like diff algorithm, whitespace handling, and case sensitivity.
  5. Click "Find Differences" to compare the texts and highlight changes.
  6. Review the side-by-side comparison with color-coded highlighting.
  7. Switch between views, copy diffs, export results, or generate patches as needed.

Pro Tip: For code comparison, use line-level diff and ignore whitespace. For JSON comparison, ensure proper formatting for accurate results. Use the patch feature to generate differences that can be applied to other files.
