Frequently asked question
No, it is not possible to change a field name in ArcGIS Online or Portal for ArcGIS. Once a field name is set and saved in its source layer, it cannot be changed. However, the display name of the field name can be changed in ArcGIS Online or Portal for ArcGIS. A display name is the field name displayed on the hosted feature layer's attribute table. Refer to ArcGIS Online: Set a display name or Portal for ArcGIS: Set a display name for more information and instructions to change a field's display name.
Alternatively, if a new name is required to ensure data precision, add a new field and copy the field values from the intended field to the new field by following the steps provided below.
The image below shows the intended field value from the 'Annual_Sales' field copied to the newly created 'Fourth Quarter Sale' field in the attribute table.
