Frequently Asked Questions
What file formats are supported for text comparison?
Our tool supports .txt, .md (Markdown), .html, and .csv files. You can also paste text directly into the input areas. The tool automatically handles different text encodings and line endings.
What's the difference between comparison modes?
Line-by-line shows differences between entire lines, word-by-word highlights individual word changes, and character-by-character shows precise character-level differences. Choose based on your analysis needs.
How does the similarity percentage work?
Similarity is calculated using advanced algorithms that compare the texts and determine the percentage of matching content. Higher percentages indicate more similar texts.
Can I ignore whitespace and case differences?
Yes! You can configure the tool to ignore leading/trailing whitespace, all whitespace, or make comparisons case-insensitive. This is useful for code comparison and formatting changes.
Is there a limit on text size for comparison?
The tool can handle large texts efficiently. For very large files (>1MB), comparison may take longer but will still work. The side-by-side view is optimized for performance with large documents.
