How to use this tool

  1. Enter first list, second list, comparison, letter case.
  2. Select Update result to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Trim each line, remove empty lines and deduplicate. Compare normalized entries as sets; preserve the first spelling and original input order.

A WORKED EXAMPLE

Using first list = apple banana pear, second list = banana pear orange, comparison = common, letter case = sensitive, the result is banana pear. Change these example inputs to match your task; use the method above to check each step.

Understanding your result

No. This is a set comparison: each normalized item appears once. Use Text Diff when line positions and repeated occurrences matter.

What to keep in mind

One item per line; leading and trailing spaces are removed. Locale-specific case equivalence is not inferred.

Common questions

Will repeated entries appear repeatedly?

No. This is a set comparison: each normalized item appears once. Use Text Diff when line positions and repeated occurrences matter.
