- Added text is shown in green, removed text in red.

What text comparison shows
Text Compare lines up your two texts and finds what is different between them, line by line. Lines that appear only in the Changed Text are additions. Lines that appear only in the Original Text are removals. When a line was edited rather than replaced, the specific words that changed are highlighted so you do not have to reread the whole line to spot the difference.
Added vs removed text
Green lines were added — they exist in the Changed Text but not the Original Text. Red lines were removed — they exist in the Original Text but are missing from the Changed Text. A line that shows both usually means a small edit: the old wording was removed and new wording was added in its place.
Common uses
People use text comparison to review edits before publishing, check what changed between two versions of a document, compare configuration or settings values, and confirm that a copy-paste did not silently drop or alter anything.
Questions and Answers
It shows which lines were added, which were removed, and which lines changed between your two texts. Where a line was edited rather than fully replaced, the exact words that changed are highlighted within that line.
Added lines appear only in the Changed Text, shown in green. Removed lines appear only in the Original Text, shown in red — they are missing from the Changed Text.
