Text Diff Checker
Compare two pieces of text and see the differences highlighted. Shows added, removed, and unchanged lines with line numbers. Options to ignore case and whitespace differences.
How to use
- Paste the original text (the ‘before’ version) into the left panel.
- Paste the updated text (the ‘after’ version) into the right panel.
- Enable options like ‘ignore whitespace’ when comparing formatted vs minified text.
- Review highlighted additions and deletions line by line.
- Use the results to write a clearer changelog entry or to reconcile two versions manually.
FAQ
Can I compare two JSON files or config files with this diff checker?
Yes. Paste both versions as text. For clearer results, format structured files first so changes align line-by-line.
What does ‘ignore whitespace’ do?
It reduces noise by treating spacing and line-ending differences as less important—useful when a formatter changed indentation only.
Is the comparison done online?
No. Diffing happens locally in your browser; your text isn’t uploaded.
Can I use this as a quick ‘git diff’ for two text blocks?
Yes—paste the two versions and review the highlights. For patch files and more advanced workflows, use Git locally.
