About Text Diff
Text Diff compares two versions of text and highlights line-level differences.
Common use cases
Debug generated output
Spot added, removed or altered lines between two program outputs or exported text files.
Check revision drift
Compare a stored baseline with a newer version before publishing or deploying it.
How it works
1
The two text inputs are split into comparable units such as lines or text segments.
2
A diff algorithm identifies matching, added and removed sections.
3
Differences are highlighted so you can review changes without altering either source.
Privacy & file handling
Text comparison runs in the browser
The two text inputs are compared locally for this utility rather than being uploaded to Zavilo for diff processing.
Limitations and important notes
- A textual diff shows changes in characters or lines, not whether the meaning of the content is equivalent.
- Large generated files can produce noisy diffs when line ordering changes substantially.
- Whitespace-only or formatting changes may appear as differences depending on the comparison mode.
Text diff vs document review
| Feature | Best for | Does not provide |
|---|---|---|
| Text Diff | Plain text, code snippets and configuration | Rich document formatting or tracked-change metadata |
| Word processor review | Formatted documents and editorial markup | Simple browser-local plain-text comparison |
