Diff Checker

About Diff Checker

Diff Checker is a developer utility for comparing two pieces of text or code to identify the differences between them. It visualizes additions, deletions, and modifications, making it easy to track changes.

How It Works

The tool uses a character or line-based differencing algorithm to analyze the "Original" and "Modified" text.

• Green Highlight: Indicates lines or characters that have been added in the new version.
• Red Highlight: Indicates lines or characters that have been removed from the original version.
• Neutral: Text that remains unchanged.

Use Cases

• Code Review: Compare two versions of a source code file to see what changed.
• Content Editing: Track edits in articles or documents.
• Config Debugging: Compare a working configuration file with a broken one to spot errors.
• Data Validation: Verify that two datasets are identical.
