How to Compare Two Text Blocks
A text diff highlights additions, deletions, and unchanged lines so you can compare configs, logs, or snippets without opening git. This tool diffs two panes side by side in your browser — no files are uploaded.
For structured JSON, the JSON diff tool is usually clearer because it compares keys instead of lines. Use text diff for YAML, SQL, emails, and anything that is not JSON.
Tips
- Normalize trailing whitespace before comparing logs that wrap differently.
- Paste the older version on the left and the newer version on the right to match git-style +/− reading.
- Very large documents may be slow — trim to the section you care about.
