Auto-Fill Data in alphabetical order?

[midsummer]

Hi,
I'm working for LCD company.

I'm looking for the easier way to input 'panel ID's.
Here is the example.

4NJ8CD001AA
4NJ8CD001AB
4NJ8CD001AC
.....

Even though I thought Auto-filling function should work, Unfortunately, it
didn't seem
to work. Instead, it generate the data like this.

4NJ8CD001BA
4NJ8CD002BA
4NJ8CD003BA
4NJ8CD004BA
4NJ8CD005BA
4NJ8CD006BA
4NJ8CD007BA

Does anyone know how to solve my problem?

Please, help me. It's annoying to input thousands of panel ID one by one.

To generate this series:

4NJ8CD001AA
4NJ8CD001AB
4NJ8CD001AC

Put in any starting cell, say in B2:
="4NJ8CD001"&CHAR(INT((ROWS($1:1)-1)/26)+65)&CHAR(MOD(ROWS($1:1)-1,26)+65)
Copy down as far as required

It is always a good idea to tell us about your layout so that when we give
you formula solutions, you can use them directly. Since you didn't tell us
what column the "panel ID's" are in, I guessed at Column D. You also didn't
tell us what row the "panel ID's" start in, so I guessed at Row 2. Manually
put the first "panel ID" in D2, then put this formula in D3 and copy it down
as far as you need to...

=IF(MID(D2,7,3)="999",IF(RIGHT(D2)="Z",LEFT(D2,6)&"001"&CHAR(CODE(MID(D2,10,1))+1)&RIGHT(D2),LEFT(D2,6)&"001"&MID(D2,10,1)&CHAR(CODE(RIGHT(D2))+1)),LEFT(D2,6)&TEXT(MID(D2,7,3)+1,"000")&RIGHT(D2,2))

Obviously, if my guess of D2 as the first "panel ID" was incorrect, then
change all the D2 references to whatever cell you put the first "panel ID"
in. Note that this formula will handle up to 999ZZ as the last 5 characters
in your "panel ID"... if you can surpass that value, then you will need a
different formula or approach (but you would have to tell us the increment
order for the remainder of the characters).
