Text Diff
Compare two texts and show differences
Text Diff is an online comparison tool that highlights additions, deletions, and modifications between two texts using color-coded visualization. It performs precise line-by-line analysis with an option to ignore whitespace changes. Ideal for code reviews, document version control, contract tracking, and any situation where you need to quickly identify differences between two pieces of text.
๐ How to Use
- Enter the original text on the left
- Enter the modified text on the right
- Click the Compare button
- Additions, deletions, and changes are highlighted in different colors
โจ Features
- โLine-by-line comparison
- โVisual highlighting of changes
- โColor-coded additions/deletions
- โOptimized for code review
- โLarge text support
๐ก Use Cases
- โขDevelopers: Compare code before and after changes to spot modified logic and potential bugs quickly.
- โขTechnical Writers: Identify differences between document revisions at a glance during editing cycles.
- โขEditors & Proofreaders: Verify that all corrections were applied accurately by comparing original and revised manuscripts.
- โขLegal Professionals: Compare contract drafts with final versions to ensure all clause modifications are accounted for.
- โขQA Engineers: Track changes in configuration files or API responses to catch unintended modifications.
- โขStudents: Compare assignment drafts to verify that instructor feedback was properly incorporated.
๐ฏ Tips
- โธEnable the whitespace ignore option to focus on substantive content changes without getting distracted by indentation differences.
- โธNormalize line endings (LF vs. CRLF) in both texts before comparing to reduce false positives.
- โธWhen reviewing code, distinguish between comment changes and actual code changes to improve review efficiency.
- โธFor very long texts, extract and compare key sections first for a more focused review.
- โธPlace the original text on the left and the modified version on the right โ this is the standard convention.
โ FAQ
Q. Can I use this for code comparison?
A. Yes, it's very useful for comparing different versions of programming code.
Q. Can I upload files directly?
A. Currently only text paste is supported. Copy and paste file contents to use.
Q. What comparison algorithm is used?
A. It uses a standard diff algorithm for line-by-line comparison. Added lines are shown in green, deleted lines in red, making changes intuitive to spot.
Q. Does it detect case differences?
A. Yes, the comparison is case-sensitive by default. Any case change will be highlighted as a difference.
Q. How large of a text can I compare?
A. You can compare texts with thousands of lines within browser memory limits. For very large files, consider comparing section by section.
Q. When is the whitespace ignore option useful?
A. It is useful when only code formatting has changed, such as tab vs. space indentation, and you want to see only substantive logic changes without the noise of formatting differences.
