We can use SQL Server Import and Export Wizard to import .ACCDB file to SQL server.
1.Open MS SQL Server Import and Export Wizard.
2.For “Data Source” choose “Microsoft Access (Microsoft.ACE.OLEDB.16.0)”. (If the data provider is not existed, please refer to this MS document to choose correct provider that corresponds to Access version)

5.Test the connection. If it works, click OK.
6.For the “Data Destination” choose “Microsoft OLE DB Provider for SQL Server”.
7.Enter the MS SQL Server name or choose from the dropdown menu.
8.Enter your SQL credentials and select the database you wish to import the data to, the database should show up in the dropdown menu if your MS SQL info is correct.
9.Select “Copy data from one or more tables or views”.
10.Select the tables you want copied and edit the mappings if needed.
11.Continue through the wizard and hit finish to begin the import.
