Airtable Schema Inspector & Diff

Paste the JSON from Airtable's Meta API (GET /v0/meta/bases/{baseId}/tables). One snapshot gives a schema map and a health report; paste a second, later export to diff them and catch breaking changes. Nothing is stored.

Schema A (required)

Schema B (optional — to compare)

Why field type changes are dangerous

Converting a single-select to a text field, or deleting a field, can silently drop data and break the automations and integrations that depend on it — and Airtable keeps no real version history. SchemaWard monitors this continuously and gives you a restore plan to put it back.
