About Text Diff Checker
Text Diff Checker compares two blocks of text and highlights every added or removed line, making it easy to spot exactly what changed between two versions — useful for comparing two drafts of a document, reviewing a config file before and after an edit, or checking what changed between two versions of code without a full version control setup.
