How Text Diff Works
Text comparison is one of the most common tasks in programming, writing, and data work. Our diff tool shows you exactly what changed between two versions of any text.
Common Use Cases
- Compare two versions of a document or contract
- Review code changes before committing
- Check what changed in a config file
- Verify translation accuracy between language versions
- Find differences in spreadsheet exports or CSV data
Frequently Asked Questions
The tool uses a line-based diff algorithm (Longest Common Subsequence) to compare texts. Lines that are identical appear unchanged. Lines that differ are shown as removed (old text) or added (new text). Consecutive removed+added pairs are grouped as "modified" for easier reading.
