how do I create an array

[Guest]

I have a column of values that look like: 00000000007310F0000

all cells are 19 chars in length, and the 15th char is alpha. I need to map
the 15th alpha char to a numeric. the mapping is as follows:

ABCDEFGHI (column F)
123456789 (column G)

this is where I'm at:
=REPLACE(C3,15,1,(IF(MID(C3,15,1)=({F3:F12}),({G3:G11}),"")))

please help

If alpha characters A through I are the only characters possible within
the text string, try...

=LOOKUP(MID(C3,15,1),F3:G11)

Otherwise, try...

=VLOOKUP(MID(C3,15,1),F3:G11,2,0)

Hope this helps!

I tried the =lookup formula and it returns a single value.

I am looking to convert 00000000007310F0000 to 0000000000731060000

I've tried wit
=REPLACE(C10,15,1,(IF(MID(C10,15,1)={"A","B","C","D","E","F"},{"1","2","3","4","5","6"},"")))

the above formula only works if the alpha char in the number string = A,
otherwise it returns false.

?

Assuming the string is in A2 and that the alpha character is always UPPER
case then

=LEFT(A2,14)&CODE(MID(A2,15,1))-64&RIGHT(A2,4)

well, I have not idea why it worked, but it did, kinda.

the range of non-numeric values is as follows:

indicating positive values (0-9) { A B C D E F G H I

indicating negative values (0-9) } J K L M N O P Q R

your solution worked when alpha values = A - I.

??

thanks!

negative values (0-9) } J K L M N O P Q R

your solution worked when the alpha number was A - I, otherwise not.

The solution I posted works by subtracting a value from the alpha character's
ASCII code. In the ASCII character set A is 65, B 66 etc.

The ranges you have just posted do not quite tie up:

positive values (0-9) { A B C D E F G H I
negative values (0-9) } J K L M N O P Q R

You now have ten values for nine letters so I am going to assume you meant

positive values (1-9) { A B C D E F G H I
negative values (1-9) } J K L M N O P Q R

in which case 00000000007310J0000 gets converted to 00000000007310-10000
and 00000000007310F0000 gets converted to 0000000000731060000

If this is what you are after then the forumla is

=LEFT(A2,14)&IF(CODE(MID(A2,15,1))<74,CODE(MID(A2,15,1))-64,CODE(MID(A2,15,1))-75)&RIGHT(A2,4)

with no validation to check that the alpha character is in the required
ranges.

If this isn't what you want then post more examples of how the conversions
should work.
