Frequently Asked Questions
Common questions about text diff checking and comparison
What is a text diff checker and how does it work?
A text diff checker is a tool that compares two pieces of text to identify differences between them. It uses advanced algorithms to analyze content line-by-line, word-by-word, or character-by-character, highlighting additions, deletions, and modifications with color-coded visualization.
Can I compare code files with syntax highlighting?
Yes, our diff checker supports syntax highlighting for over 50 programming languages including JavaScript, Python, Java, C++, HTML, CSS, and more. The tool automatically detects the language and applies appropriate highlighting for better readability.
How do I merge changes between two text versions?
Our interactive merge feature allows you to select specific lines or sections from either version and copy them to create a merged result. You can resolve conflicts manually by choosing which changes to keep, providing full control over the merge process.
Is my data secure when using the diff checker?
Absolutely. All text comparison and processing happens locally in your browser. No content is transmitted to our servers, ensuring complete privacy and security for your sensitive code and documents.
