Extension attributes are not provided in the CSV template since they vary by each configuration, but you can add them if needed. Extension attributes are dynamically mapped using the "EA " prefix in the column header (note the space after "EA"). For example, if the CSV data contains a column named "EA Memo1", the inventory preload update process will map the value in that column to an existing extension attribute in Jamf Pro named "Memo1".
The extension attribute field functions differently than the other fields when a CSV file is uploaded to Inventory Preload. For example:
If the extension attribute field is empty in the uploaded CSV file, the existing extension attribute value is removed from the inventory record.
If any other field is empty in the uploaded CSV file, the current value for the field is retained in the inventory record.
