I was given this formula to use with this document but its not working for me.
"Copy this formula and save it somewhere.
=iferror(text(date(right(L1,4),mid(L1,find(""/"",L1)+1,find(""~"",substitute(L1,""/"",""~"",2))-(find(""/"",L1)+1)),left(L1,find(""/"",L1)-1)),""MM/DD/YYYY""),"""")
Everytime you receive the source data, paste that to M1.
And then drag it downwards.
After dragging it downwards, copy column M and then paste it over column L as VALUES."
