Connected fields are fields within a [connected table](/v1/docs/creating-connected-tables) that are connected to an app, service, or folder of CSV data. Connected fields appear with a ![connected field icon](https://cdn.document360.io/dd260e4e-10bb-4b66-8fb3-5504c272b904/Images/Documentation/plug_small.png?sv=2026-02-06&spr=https&st=2026-10-15T04%3A55%3A36Z&se=2026-10-15T05%3A55%3A36Z&sr=c&sp=r&sig=bvBupuueKGXR2FOvhiEzzmUXw6gwwieqPH2tD5cJsvY%3D) icon on the **Field Settings** page. Since the data in connected fields comes from an external service, you can't edit the data in connected fields or add a new record to a connected table. This helps to keep your data in sync across multiple services and eliminate potential confusion about which system contains the most up-to-date information. To add or update a record with the most current data available in the connected data source, [refresh your connected table](/v1/docs/refresh-a-connected-table). You can [rename connected fields](/v1/docs/change-the-properties-of-a-field-from-a-legacy-form) and [change the field types](/v1/docs/change-the-properties-of-a-field-from-a-legacy-form). You can also [connect more fields](/v1/docs/add-more-connected-fields) any time. ## Supported field types The following field types are supported for connected fields: - Address - Checkbox - Date - Date/Time - Duration - Numeric - Text - Time of Day > [!NOTE] > Note: Through a connection, Quickbase fields are simplified as needed to fit the types listed above.
