Text Diff
Compare two text blocks line by line.
About Text Diff
Text Diff compares two blocks of text side by side or inline, with an option to ignore whitespace for cleaner reviews.
Common uses
- Compare configuration changes before pasting them into a ticket.
- Review generated output against an expected result.
- Ignore whitespace when only formatting changed.
Good to know
For source code projects, a version control diff is still best. This page is meant for quick browser-based comparisons of pasted text.
How to compare text
Paste the original and changed text, then decide whether whitespace should matter. Ignoring whitespace is helpful for formatting-only changes but can hide meaningful indentation in some formats.
Good review habits
Use the diff to inspect copied configuration, generated examples, documentation edits, or command output before sharing them. Small line changes are easier to catch side by side.
Common mistakes
For source-controlled code, use your version control diff as the final authority. This browser tool is for quick pasted comparisons, not repository history.
Before you rely on the output
- Retest patterns and comparisons in the final runtime when whitespace, line endings, locale, or regex-engine differences can change the result.
- Privacy mode: inputs are processed locally in your browser and are not intentionally sent to an application server.
