Prevent Numbers from resolving "equations" on importing
We have a database of items that uses the following system of categorization: category/sub-category, where both "category" and "sub-category" are numbers. So a unique identifier for an item might be "199/23"
Even though the field that holds this identifier in the database is a text field, when I export records from the database that includes this field and open the exported file in Numbers, Numbers will resolve the implied equation and "199/23" comes through as "8.6521739." Even if I then explicitly format that cell as text, since the conversion has already taken place, it does not revert to the way I need it to be.
I do not have the option of changing the database. How can I force Numbers to import "199/23" as a text string?
Thanks in advance.
