1) Is not necessary as Access uses multi-valued fields
2) Is not necessary as Access converts multi-valued Excel columns into multiple columns when you run a Make Table query

5) None of the above are correct

Answer 1

Converting multi-valued columns in Excel into multiple columns is necessary before importing data into Access.

Step-by-step explanation:

The correct answer to the question is option 5) None of the above are correct.

Before importing data into Access from another source, like Excel, it is necessary to clean the data. Converting multi-valued columns in Excel into multiple columns is important because Access does not natively support multi-valued fields. Access treats each value in a multi-valued Excel column as a single value rather than multiple values.

By converting multi-valued columns in Excel into multiple columns, you ensure that the data in Access is structured correctly and can be properly utilized and analyzed.
