Question $7$

After changing the number formatting on a row of cells you notice that some of the existing data have transformed into rows of hashes $($#####$).$ What is the cause of this problem?

$1$ point

This isn$$t a problem, the user simply chose a Number Formatting that transformed the data to a type that now reads as rows of hashes.

Number formatting doesn$$t recognize the original data format and doesn't understand what to do with it$.$

Number formatting changed the text into something longer than it was before and has become too long for current column size.

Number formatting is changing the existing data to the new format specified and the file needs to be reloaded.
