what is 'tick mark' in corner of cell ?

I just exported some data from Access to Excel.

There is a little 'tick mark' in the upper left corner of some cells.

Anybody know what that is?

thanks for any help.

This indicates that Excel has found a potential problem with the
value or formula in the cell. Most likely in your case, it is
that a number is being stored as text.
