text field to checkbox on imported excel sheet

[Relative Begginer]

Hello. I imported an Excel sheet into Access creating a new table. We have
a text column that I would like to make into a check box column. The data is
essentially y/n already. I need to know what replace the "x" we have now (for
"yes") with so when I go to design view and change the field Access doesn't
erase the data just makes it a "yes" if there's an "x" in the field or "no"
if the field is blank.

Would I replace "X" with 1/0, y/n or something else? Would I need to not
have blank record entries? In the example below, use a 1/0 approach instead
of using "X".

Example:
Header is "School"
Record 1 is "X"
Record 2 is " " (Blank)

Thank you for any help you can give me!

If you are only interested in changing for reporting purposes then just use a
calculated field in the query like this --
Attended: IIF([School] = "X", "Yes", "No")

Yes/No fields store the data as True/False. If you change your "x" to True,
it should import fine. You don't have to change your blanks to False, but you
may want to. I'm not sure if it matters in the end, but sometimes it's better
to be safe than sorry.
