What is Text Diff?

Text Diff is a tool that compares two versions of text and highlights the differences between them. It's essential for:

Code Review: See what changed between code versions

Document Editing: Track revisions in documents

Content Management: Compare different versions of content

Data Validation: Verify if two datasets match

How Text Diff Works

The tool analyzes both texts line by line and identifies:

Added Lines: Content present in the second text but not the first

Removed Lines: Content present in the first text but not the second

Unchanged Lines: Content that appears in both texts
