List comparison
Find shared items, differences, and duplicates in two lists.
About List comparison
Treat each line as an item and compare membership between two lists. This is useful for reconciling filenames, IDs, tags, or other values where line order is not the main question.
Steps, example, and limitations
How to use it
- Paste the two lists, one item per line.
- Set the comparison and normalization options.
- Run the comparison and copy the shared or differing items you need.
Example
Input
List A: apple, pear List B: pear, plum (Enter each item on its own line.)
Result
Shared: pear Only A: apple Only B: plum
Things to know
- Case or whitespace normalization can merge values that were originally different.
- Use text diff when order and line-by-line changes matter.
