I have a column in a worksheet which has a list of 3 digit numbers. I want to
change the 3 digits to become 4 digits, the new fourth digit has to be a
leading zero, i.e 355 to become 0355. I prefer the format of the digits to be
a number but a text format would not be a problem.

The length of the digits in the column are not static. i.e one month there
may be 200 rows of data the next might be 300 and I would want the macro to
cater for this variation.

Thanks
