Find differences in text
When you need more than “the documents differ” and want to know where exactly the edit is, character-level highlighting helps. The service finds added, removed and changed lines, and inside a changed line it marks the exact characters. That is how a moved comma, an altered digit or a replaced word is found — things that are easy to miss when reading by eye.
Supported: .conf, .css, .csv, .docx, .htm, .html, .ini, .js, .json, .log, .md, .pdf, .php, .py, .sh, .sql, .ts, .tsv, .txt, .xls, .xlsx, .xml, .yaml, .yml. Limit: 10000 lines for two documents. Nothing is stored — only a fingerprint of the pair stays on the server.
Features
- Three kinds of difference: added, removed, changed
- Highlighting inside a line, not just per line
- The “ignore spaces” option removes formatting noise
- Two-column line numbering for exact reference
- Copy the result with one click
Questions and answers
How do I find differences between two texts?
Paste both versions into the panes and press “Compare”. Changed lines are highlighted, and inside them the changed fragments.
Why are line breaks treated as a difference?
Files from Windows and Linux use different line-ending characters. Such differences are normalised automatically and do not create noise.
Can I ignore case?
Yes, enable the “Case” option and “Text” and “text” count as the same.
Is it suitable for comparing translations?
Yes. It is convenient for checking translation revisions: you see which sentences changed between editions.
