After setting your search criteria and launching your search for data records pertaining to a specific entity, you can export your search results in an XLSX or CSV file. Besides, you can also import data records from an XLSX or CSV file. This could be very interesting if you have some kind of mass update on a group of records. You search for the records, export the search results, do your updates in the file and finally import the records into MDM again.
You are allowed to define the maximum number of data records to be exported or imported in Talend MDM Web UI. For more information, see How to define the maximum number of data records to be imported or exported in Talend MDM Web UI.
