Changing an Airtable field from multiple select to single-select — what breaks
Converting a multiple select field to single-select in Airtable can silently drop data and break filters, views, and automations that depend on it. Here's exactly what changes, how to check before you commit, and how to monitor for it.
Check it before you commit. Paste your base schema into the free Airtable Schema Inspector to see exactly what changed and whether any change risks data loss.
SchemaWard monitors your Airtable base structure continuously and alerts you the moment a breaking change like this happens — with a point-in-time restore plan to put it back.
