Split a Full Name column into First + Last.
CSVTidy detects your name column and creates 'First Name' and 'Last Name' columns beside it. It handles honorifics (Dr., Mrs.), suffixes (Jr., III), and the 'Doe, John' comma-separated form.

Common questions
How does it handle middle names?
Middle names go into the First Name field, matching what most CRM imports expect.
What about 'Doe, John'?
When the first token ends with a comma it is treated as the last name, and the remainder becomes the first name.
What about compound surnames like 'van der Berg'?
Those are genuinely ambiguous — 'van' and 'de' are given names in some cultures. Automated splitting will get some wrong, so keep the original column and review compound names by hand.
