입력 / Input: Alpha alpha Alpha 결과 / Result: Alpha alpha
Steps to verify
- Check case requirements.
- Review retained spelling differences.
- Set a separate convention if normalization is needed.
How to interpret the result
Repeated Alpha is removed while alpha remains a different string. Business meaning is separate from string comparison.
Deciding what to do next
Product codes and account names may distinguish case. Check the source system before converting everything to lowercase.
Feature scope
Keep first-occurrence order while removing matching strings, with trim and empty-line options and case-sensitive comparison, not semantic merging.
Frequently asked questions
Does it automatically lowercase everything?
No. It matches identical strings.
