Text Diff Checker
Updated on:Compare two texts and find line-by-line differences.
How it works
1. Paste original text. 2. Paste modified text. 3. Click Compare.
When to use it
Text comparison is essential for:
- Code review: compare two code versions to identify changes made.
- Contracts: verify differences between two contract versions to identify modified clauses.
- Translation: compare original text with translation to verify completeness.
- Proofreading: highlight differences between the original and corrected draft.
- Versioning: compare successive document versions when you don't have a version control system.
Advantages
Highlights differences with colors. Options to ignore case and whitespace.
Benefits vs alternatives
Advantages of our tool:
- Visual highlighting: added, removed and modified lines with distinct colors.
- Flexible options: ignore case and whitespace for meaningful comparisons.
- No software: no need for Git diff or dedicated software. All in the browser.
- Privacy: compared texts are not saved or transmitted.
Common mistakes to avoid
- Ignored whitespace: when comparing code, spaces and tabs matter. Disable "ignore whitespace" for precise comparisons.
- Different encoding: files with different encodings (UTF-8 vs UTF-16) can show non-existent differences. Normalize encoding before comparing.
- Different line endings: Windows uses \r\n, Linux uses \n. This can generate false differences on every line.
- Text too long: for very large comparisons, the tool may slow down. Split texts into smaller sections.
