   * Excel Import: QFQ offers functionality to directly import excel data into the database. This functionality can
     optionally be combined with saving the file by using the above parameters like `fileDestination`.
+    The data is imported without formatting. Please note that this means Excel dates will be imported as a number
+    (e.g. 43214), which is the serial value date in Excel. To convert such a number to a MariaDb date, use:
+    `DATE_ADD('1899-12-30', INTERVAL serialValue DAY)`.
 
     * *importToTable*: <mariadb.tablename> - **Required**. Providing this parameter activates the import. If the table
       doesn't exist, it will be created.
