New cell with range between two cells - formula

Question

I have a cell with vehicle model years (starting A:2 and ending B:2) for example A:2 is 1997 and B:2 is 2001 How can I make the single cell C:2 show the range of years for example 1997 1998 1999 2000 2001 I need this for a shopping cart that will query specific years. My files have about 15,000 rows so I need to do this with a formula.
I need the end result to go into either the single cell c:2 or to populate in single cells to the right example c;2 d;2 e;2 etc. It is preferred to have them in a single cell separated by a space not a comma as this will be uploaded as a .csv file.

Answer 1

In C2 enter:
=A2
In C3 enter:
=IF( MAX($C$1:C2)=$B$2,"",C2+1)
and copy down
EDIT#1:
In order to place the result into a single cell run the following macro rather than using formulas:
Sub SpanOfYears()
Dim FirstCell As Range, SecondCell As Range, Result As Range
Dim I As Long
Set FirstCell = Range("A2")
Set SecondCell = Range("B2")
Set Result = Range("C2")
For I = FirstCell.Value To SecondCell.Value
Result.Value = Result.Value & " " & I
Next I
End Sub
with this result:
EDIT#2
Macros are very easy to install and use:
ALT-F11 brings up the VBE window
ALT-I
ALT-M opens a fresh module
paste the stuff in and close the VBE window
If you save the workbook, the macro will be saved with it.
If you are using a version of Excel later then 2003, you must save
the file as .xlsm rather than .xlsx
To remove the macro:
bring up the VBE window as above
clear the code out
close the VBE window
To use the macro from Excel:
ALT-F8
Select the macro
Touch RUN

Macros must be enabled for this to work!
