Hello, I am having a consistent #N/A error when I try to convert a Base36 alpha numeric string into a pure numeric string that represents where in the Base36 alphabet the digit represents. For example, for Base 36, the number 0 is 0, the letter F would represent 15 and W would represent 32. The alphabet is "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ" and I listed it in Column A, with numeric representations in Column B, represented here:

If have C3 = W on the same sheet, I wanted to use the Index-Match to do the following:

D3=Index($A$1:$B$36,match(C3,$A$1:$A$36,0),2)

I am expecting the value of D3 = 32 but I get #N/A. Any suggestions here? Greatly appreciated!
 
Those two functions are not compatible:

[Table="width:, class:grid"][tr][td="bgcolor:#C0C0C0"][/td][td="bgcolor:#C0C0C0"]
A​
[/td][td="bgcolor:#C0C0C0"]
B​
[/td][/tr][tr][td="bgcolor:#C0C0C0"]
2​
[/td][td]
9​
[/td][td]A2: Input[/td][/tr]
[tr][td="bgcolor:#C0C0C0"]
3​
[/td][td="bgcolor:#E5E5E5"]9[/td][td]A3: =CHAR(A2+48+7*(A2>9))[/td][/tr]
[tr][td="bgcolor:#C0C0C0"]
4​
[/td][td="bgcolor:#E5E5E5"]
2​
[/td][td]A4: =CODE(A3)-48-7*ISTEXT(A3)[/td][/tr]

Excel Facts

VLOOKUP to Left?
Use =VLOOKUP(A2,CHOOSE({1,2},$Z$1:$Z$99,$Y$1:$Y$99),2,False) to lookup Y values to left of Z values.

I think the problem may have to do with real numbers versus text numbers. I think these two should work no matter which...

To go from a Decimal number (0 to 36) to Base36 "digit"...

=CHAR(A1+48+7*(--A1>9))

To go from Base36 "digit" to Decimal number...

=CODE(A1)-48-7*ISERR(--A1)
