- Compare code, configuration files, and generated output.
- Find small changes hidden inside otherwise similar text.
Text Diff Viewer questions
What do additions and deletions mean in a text diff?
Additions appear only in the revised text, while deletions appear only in the original. Changed lines usually contain a combination of both.
Can I compare code with the Text Diff Viewer?
Yes. It works with plain text, so you can compare source code, JSON, SQL, Markdown, configuration, and prose.
