Diff Checker
Compare two texts or code files and highlight every added, removed and changed line and word.
Diff Checker
Paste an original and a changed version to see exactly what differs. Changed lines are highlighted, and within them the changed words or characters, so a single altered comma stands out. View the result side by side or in one column, and ignore case or whitespace to focus on real changes. Comparison runs in your browser with the jsdiff library.
How to use Diff Checker
- Paste the original text on the left and the changed text on the right.
- Choose side-by-side or one-column view, and word or character highlighting.
- Tick Ignore case or Ignore whitespace if those changes do not matter.
- Read the summary of added and removed lines, and scroll through the changes.
When it comes in handy
- Seeing what changed between two versions of a contract, article or policy.
