Text Diff Documentation

Compare two text blocks and highlight the exact additions, removals, and changes between versions.

The browser aligns lines with a minimal-edit diff, pairs changed lines, and highlights changed words. Use a side-by-side or unified view, and hide unchanged context when needed.

• Compare configuration or source text after inserted or removed lines.
• Review word-level changes and export a patch for another tool.

Input

Text, files, or values entered in the browser, depending on the tool.

Output

A result shown in the browser that can be reviewed or copied where supported.

• Line alignment minimizes inserted and deleted lines; changed words are highlighted within paired replacement lines.
• Downloaded patches include the complete compared text rather than contextual hunks.

Inputs for this browser-side tool are processed locally and are not sent to SiteIndex. Normal page analytics may still be collected as described in the Privacy Policy. Read the Privacy Policy.
