Organization List Cleanup — JavaScript Demo

Personal JavaScript data-preparation demo using entirely fictional organizations and contacts. Not a client project or a live integration.

Seven input rows produce three organization records: two duplicates merged, one incomplete record deferred, and one opted-out contact excluded. Two template drafts are prepared for manual review; no messages are sent.

The local script normalizes names, cities and addresses and matches exact normalized keys. Separate branches remain separate. Empty input, missing or conflicting contacts and repeated opt-outs were checked. No external websites, APIs or AI models were called. Email format checks do not prove mailbox existence or deliverability. Different address spellings and translations need manual review.
