Macro For Equaling The No Of Digits & Prefixing The Numbers

I have some numbers around 200 numbers which are not same digits i.e. if 1st number is 7 digits, 2nd number is of 10 digits.

Like this even if i have a number of 1 or 2 digits then all number should have equal digits i.e. in 200 numbers if one numbers is of 13 digits then all the numbers should be 13 digits.

To do this first i am doing this to the right align & comparison all numbers & taking the highest digit number & pre-fixing the other numbers with zeros’ so that all number are equal in number of digits. This is taking huge time.

I want to make a macro or any easy method so that all should have equal no of digits.

I want that if 200 numbers are pasted in the column E i.e. from E2 to E201 then all should be converted to equal digits number by prefixing zeros & should appear in column G from G2 to G201.

And after converting them it should be prefixed with D/ OR D/ABC:

This will be present in B2 cell i.e. this cell will be blank always. And once I have any thing in that cell that should be prefixed to the converted numbers in the column G & they should appear in Column I.

And again the numbers in column G should be prefixed with the content in B2 & should appear in column K in the Ascending order sorted.

Suppose if , I have 500 numbers then they should be converted automatically to equal digits & appear in Column G & prefixed with the contented in cell B2 should appear in Column I & sorted series in ascending order with prefixed with cell B2 in the column K.

And if I have 15 numbers only then it should do the same job easily. Here the numbers of numbers are not defined.

All this should be get done on click of the command button.
