Compare Text Files Online: Find Differences Instantly
Need to see what changed between two versions of a file? Our Diff Checker highlights additions, deletions, and modifications in seconds.
Introduction
Tracking changes in code or text documents can be a nightmare if you're doing it manually. Did you fix that typo? Did you add the new function? TekToolHub's **Diff Checker** visualizes the differences between two blocks of text side-by-side.
How It Works
We use a standard "diff" algorithm to compare the Original Text (Left) with the Modified Text (Right).
- **Green:** Added lines.
- **Red:** Deleted lines.
- **Yellow/Highlight:** Modified content within a line.
Use Cases
- **Developers:** Compare code snippets before committing.
- **Writers:** See edits made by an editor or proofreader.
- **Legal:** Compare contract versions to ensure no unauthorized changes.
How to Use
- **Paste Original:** Put your old text in the left box.
- **Paste Modified:** Put your new text in the right box.
- **Compare:** Click the button.
- **Analyze:** Scroll through to see the highlighted differences.
Spot the difference instantly with **Diff Checker**.
