I have a very long list of numbers in column A and I would like a code to tell me which numbers are missing from the sequence. Below is an example.

Excel 2010
A
SS9822
SS9824
SS9826
SS9828
SS9830
SS9831
SS9833

<colgroup><col style="width: 25pxpx" https:="" www.mrexcel.com="" forum="" usertag.php?do="list&action=hash&hash=DAE7F5"" target="_blank"></colgroup><colgroup><col></colgroup><thead>
</thead><tbody>
[TD="align: center"]4565[/TD]

[TD="align: center"]4566[/TD]

[TD="align: center"]4567[/TD]

[TD="align: center"]4568[/TD]

[TD="align: center"]4569[/TD]

[TD="align: center"]4570[/TD]

[TD="align: center"]4571[/TD]

</tbody>

​



So from above the following numbers are missing so I would like a list of these made in column D.

Excel 2010
D
SS9823
SS9825
SS9827
SS9829
SS9832

<colgroup><col style="width: 25pxpx" https:="" www.mrexcel.com="" forum="" usertag.php?do="list&action=hash&hash=DAE7F5"" target="_blank"></colgroup><colgroup><col></colgroup><thead>
</thead><tbody>
[TD="align: center"]4565[/TD]

[TD="align: center"]4566[/TD]

[TD="align: center"]4567[/TD]

[TD="align: center"]4568[/TD]

[TD="align: center"]4569[/TD]

</tbody>

​



Thanks

I really need the code to cater for letters on the end and more than 8 if possible. Thanks.

Excel Facts

What is the fastest way to copy a formula?
If A2:A50000 contain data. Enter a formula in B2. Select B2. Double-click the Fill Handle and Excel will shoot the formula down to B50000.
The sample you sent me already had the parts after removing the letters on the end.
Therefore, this code ignores the ones that end with letters. Do you need the letters to be removed and the resulting part to remain there for processing?

In a nutshell the prefix in a file will be the same and the amount of characters in each cell may vary. Also some may have letters on the end.

Ricks code seems to work great but only up to 8 characters in a cell. So if that can be increased....

End Sub
Click to expand...

To sum up.

1. All the letter prefixes will be the same in each file, but the length of them will vary depending on the file I use it on.
2. Some cells will have letters on the end in varying lengths, and some may not in a file.

So if I have FASS12345ABC then FASS12347A the code has almost to forget there is letters on the end and tell me FASS12346 is missing.

I think from your example above that is what it may be doing in a way.

Thanks.

If the lowest part number is FASS50000, should the missing list start with FASS00001 or FASS50001?

Whatever the next number would be so if it starts FASS60000 then FASS60001

All right, the letters on the end will be removed and the part will be processed.
I will be back soon.

This seems to work:

Thanks worf but I still don't seem to get the desired results. Plan2 sheet which has the result column it is missing the prefixes? And I take it sheet 1 is a helper sheet?
