Frequently Asked Questions

How do I remove duplicate emails from a CSV in Excel?

Excel's dedup removes the whole row, not just duplicates by email column. Structra lets you deduplicate specifically by the email column while keeping all other data intact.

Does email dedup ignore case?

Yes. Structra treats john@company.com and JOHN@COMPANY.COM as duplicates — which is correct per email RFC standards.
