Customer list cleanup and merge (demo). Demo build on invented data: a shop export and a newsletter export (1,554 rows) merged into one clean list of 1,100 people, one row per email. Emails, phones, states and dates in one format; the 454 rows set aside each keep their reason. Delivered as CSV and Excel with a change log.
