Compare Two Lists

Paste two lists below to find matching values, values only in List A, values only in List B, and a combined distinct list. This is useful for comparing Excel columns, IDs, emails, or any datasets.

List A:

List B:

Ignore case
Trim whitespace
Remove blank lines

In both lists:

Only in List A:

Only in List B:

Combined distinct list:

How It Works

This tool compares each line in List A and List B after optional trimming and case normalization. It then groups values into matches, unique values, and a combined distinct list.

Example

List A:

apple
banana
cherry

List B:

banana
cherry
orange

Results:

In both: banana, cherry
Only in A: apple
Only in B: orange
Combined distinct: apple, banana, cherry, orange
