About This Tool
The Text Diff Tool visually highlights the differences between two blocks of text. It acts similar to 'git diff', showing exactly what was added or deleted. It operates entirely locally without sending your sensitive code to any server.
When to Use
- Comparing two versions of a code snippet to see what changed.
- Reviewing a document or article to spot grammatical corrections.
- Finding subtle differences between similar configuration files.
- Checking the output of a regular expression replace function.
Practical Examples
By Line ExampleCompares massive log files chunk by chunk.
By Word ExampleIdeal for short paragraphs where just a single word changed.
Common Mistakes to Avoid
- Comparing heavily minified (1-line) files in 'By Line' mode makes it impossible to see the exact change. Format files first, or use 'By Word' mode.
