Before you upload

Clear Campaign / Ad Set / Ad ID A filled-in ID tells Meta to edit an existing object. If the ad came from another account you get "The ID doesn't belong to this ad account" on every row. Leave this on to create new ads. Clear read-only export columns Preview Link, Instagram Preview Link, Permalink, Creation Package Config ID. Meta writes these on export; they carry stale ad IDs. Add - P1, - P2… to campaign names Each upload creates its own campaign. Without this they all share one name and are hard to tell apart when you merge them.

Duplicate ad names in the same ad set

Meta's AI is turned off on every file — automatically Advantage+ creative, Essential enhancements, text optimisation, auto overlays, Advantage+ audience and detailed-targeting expansion are all forced off on every row. A blank cell is not off — it means “use the account default”, and the default re-enrols the ad, so the values are written in explicitly and the columns are added when your export didn't include them. Nothing to tick.

Upload these one at a time Meta creates a separate campaign per upload. Once they're all in, move the ads into a single campaign and delete the empties. Start with the smallest file to check it goes through before you commit the big one.
