Text Diff Checker

What is Text Diff Checker?

Text Diff Checker is a powerful tool that compares two text documents or code files to identify differences, changes, and modifications. It's essential for developers, writers, editors, and anyone who needs to track changes between document versions.

Comparison Modes

How to Use

1. Paste your original text in the left text area
2. Paste the modified text in the right text area
3. Select your comparison mode and adjust options as needed
4. Click "Compare Texts" to see highlighted differences
5. Review the results with color-coded changes

Common Use Cases

• Code Review: Compare code versions to see what changed
• Document Revision: Track changes between document versions
• Plagiarism Check: Compare texts for similarity
• Configuration Management: Compare config file changes
• Academic Writing: Compare research paper versions
• Legal Documents: Track changes in contracts and agreements
• Content Management: Compare website content versions

Key Features

• Visual Highlighting: Color-coded differences for easy identification
• Multiple Comparison Modes: Character, word, line, and semantic comparison
• Advanced Options: Ignore whitespace, case sensitivity, and more
• Detailed Statistics: Get counts of additions, deletions, and changes
• Quick Actions: Swap texts, clear content, and reset with one click
• Real-time Updates: See character and line counts as you type

Best Practices

• Use character-level comparison for code and exact text matching
• Use word-level comparison for documents and articles
• Enable "Ignore Whitespace" when comparing code with formatting differences
• Enable "Ignore Case" when case sensitivity doesn't matter
• Use line numbers for easier reference in long documents
• Save important comparisons for future reference
