I need to try to create a formula to convert numbers to letters using the
following scale:

0 = A
1 = B
2 = C
3 = D
4 = E
5 = F
6 = G
7 = H
8 = I
9 = J

Such that 12.34 would be transformed to BCDE.

This is the formula I had tried, but it won't accept:

=CONCATENATE(HLOOKUP(RIGHT(ROUNDDOWN(M2/10000,1),1),A1:J2,2),HLOOKUP(RIGHT(ROUNDDOWN(M2/1000,1),1),A1:J2,2),HLOOKUP(RIGHT(ROUNDDOWN(M2/100,1),1),A1:J2,2),HLOOKUP(RIGHT(ROUNDDOWN(M2/10,1),1),A1:J2,2),HLOOKUP(RIGHT(ROUNDDOWN(M2,1),1) ,A1:J2,2),HLOOKUP(RIGHT(ROUNDDOWN(M2*10,1),1),A1:J 2,2))

M2 is my starting number and the table array is the Number/Letter Conversion
Chart.

I truly hope someone can help me.

Thank you,
Chris
