A SharePoint list with a multivalued lookup list referring to another table
An Excel sheet with comma-seperated mutlivalued data
We want
Import the Excel sheet into SharePoint via Access
Issue
Access is not capable to translate the multivalued fields during the import :-(
Steps to Workaround
Prepare your data in Excel for import
Split your data into two tables, one with and another without the multivalued field.
Both tables have to be equipped with a unique ID to match them together in a later step.
Load the table with the lookup references into Excel
In the table with the multivalued fields, translate the bound display values in bound values using vreplace-function
Open the SharePoint list as linked table in Access
Import the data from Excel, without multivalued fields into the SharePoint list
Import the data with the multivalued data into a temporary table
