Open Text compare. Paste the original text on the left and the changed text on the right, or load each from a file, then press Compare.
- Changes are highlighted down to the character.
- Choose Side by side or Inline view.
- Tick Ignore case, Ignore white space or Ignore blank lines to hide small differences, or Show only differences for long texts.
- Swap sides exchanges the two texts.
For JSON, use JSON compare, which ignores key order and formatting.
