List comparison outputs
The comparison returns five result panels: only in A, only in B, in both lists, union, and symmetric difference. Each panel can be copied independently.
Common uses
Compare email segments, product IDs, keyword sets, inventory exports, URL lists, user IDs, or any line-based data from spreadsheets and text files.
FAQ
What is symmetric difference?
Symmetric difference means items that appear in one list or the other, but not both.
Are duplicates removed before comparing?
Yes. Each list is treated as a set after optional trimming and empty-line removal.
Can I compare case-insensitively?
Yes. Ignore case is enabled by default and can be turned off.
