If they are just formatted like that then you need to change the format to
NUMBER.

If the numbers are in Col A then you can test by
=ISNUMBER(A1)
in B1
If the result is TRUE then just change the format
If it is false then use the formula
=IF(RIGHT(A1,1)="B",(LEFT(A1,LEN(A1)-1))*1000000000,IF(RIGHT(A1,1)="M",(LEFT(A1,LEN(A1)-1))*1000000,A1))
in B1 and copy down
