Re: library book location formula
hmm...how does the Dewey Decimal system work?
A place to start:
1. determine what letter code the book is in (either 1 or 2 left characters)
2. determine the number values: use the SEARCH() function on "-" to determine the left and right side range and MID() and RIGHT()
3. Use two lookups, one for the letter, then a dependent one based on the number start and end
Is this a school assignment? If not, I can be less cryptic
