Question

If the value of cell is 6 for example, how to output dynamically as followed in excel:

6
A1~A2
A2~A3
A3~A4
A4~A5
A5~A6

Answer 1

Ok, then I would suggest you copy this formula for 20 rows, or as many as you need:

 =IF(A$1>ROW()+1-ROW(B$1),"A"&ROW()+1-ROW(B$1)&"~A"&ROW()+2-ROW(B$1),"")

Then you would get your result, when you set

A1 = 6

and

B1 = IF(A$1>ROW()+1-ROW(B$1),"A"&ROW()+1-ROW(B$1)&"~A"&ROW()+2-ROW(B$1),"")

Hope this helps.

EDIT:

B1 = IF(A$1>ROW()+1-ROW(B$1),"A"&CHAR(ROW()-ROW(B$1)+65)&"~A"&CHAR(ROW()-ROW(B$1)+66),"")
