LookUp Problem

[LostNFound]

I need to look at a single cell and it will contain a value from 1-1000, I
want to return different letters based on the cell value. Using ranges for
different letters>>

Example - 1-100 will return an A, 101-150 will return a B, etc. all the way
to 1000 in increments of 50.

The column C will contain the a number between 1 and 1000 and I want to
return a letter based on the example above in a different column.

One way ..

Assuming lookup values entered in A1 down,

Put in say, B1:
=IF(A1<1,"",VLOOKUP(A1,{1,"A";101,"B";151,"C";201,"D";251,"E";301,"F";351,"G";401,"H";451,"I";501,"J";551,"K";601,"L";651,"M";701,"N";751,"O";801,"P";851,"Q";901,"R";951,"S";1001,"T"},2))
Copy down

Try this:

=IF(OR(C1="",C1>1000),"",IF(C1<101,"A",CHAR(64+CEILING(C1,50)/50-1)))
