About text diff checker
How it works
The Text Diff Checker compares two versions of text and highlights the differences. It supports three levels of granularity: character-level, word-level, and line-level comparison. The tool shows additions in green and deletions in red for easy reading.
Use cases
- Track document revisions — see what changed between versions of a contract or proposal
- Code review — compare different versions of source code
- Content editing — review changes made by editors or reviewers
- Version control — understand diffs when merging branches
- Data comparison — spot differences between two datasets
Comparison modes
The tool offers three ways to analyze differences:
- Character mode — highlights every changed character (most detailed)
- Word mode — shows changed words, ignoring whitespace differences
- Line mode — displays added or removed lines (best for documents)
Input examples
Paste any text format into the left and right panels:
- Paragraphs of prose — compare different drafts of an article
- Code snippets — see what changed between versions
- Lists and tables — track additions and removals
- JSON/XML — compare structured data formats
