 ### Typical Use Cases
 
 The Data Importer extension allows you to import data from Excel and CSV files directly into your app. You can create a Data Importer document to define which columns to import and an NPE to hold the imported data, along with source-to-target mapping.

 ### Support for Mapping Parameter in Import Mapping {#mapping-param-import-mapping}
 
-Mapping Parameter (https://docs.mendix.com/refguide/import-mappings/#mapping-parameter) is now supported by Data Importer starting with Mx 10.21. Mapping Parameter can be used to create associations with imported data. Primitive types are not supported but any Mx object type can now be passed as *Mapping Parameter*.
+The [Mapping Parameter](/refguide/import-mappings/#mapping-parameter) is supported by Data Importer starting from Mendix 10.21.
