### Handle the names a formula gets wrong

A text-to-columns split breaks on the second space. Maria van der Berg becomes three people. Dr and Jr end up as first names.
**This tool keeps particles with the surname and sets prefixes and suffixes aside.**

### Fix the field the form got wrong

A web form sends one Name field. The CRM drops the whole name into First Name and leaves Last Name empty. The same person already has a record with it right.
**Dedupely finds the record that already exists for that person and merges the two.**
