Frequently Asked Questions

How does the diff comparison work?

The tool performs a line-by-line comparison between the original and modified text. Lines that exist only in the original appear with a red background, lines only in the modified version appear with a green background, and matching lines show no highlight.

Can I swap the original and modified text?

Yes. Click the Swap button to exchange the contents of the original and modified panels, then re-run the comparison.

Does it show line numbers?

Yes. Each line in the diff output includes its line number for easy reference, along with a + or − indicator showing whether the line was added or removed.
