The data are % which could be negative. The '' '' was just to say that the
series are continuing following the same pattern. These % are not in order.
Each group of five are data associated with one compound. They have to be
rearranged because they are automatically plotted on a graph with very
complex algorythms.

Thanks for your interest to fix my problem.

gaetae,
1. if u say numbers, on column A,
a. is it in sequence <min to max or max to min
b. is it a mixture of different numbers, not in order, (i.e. %,
Currency, Date, etc.)
c. if it is "", do you mean it is a blank cell, or a text number "n" ?
pls. be specific about the details of your numbers, for any reason why you
group them..

Hi, I'm using Excel 2003 on Windows. I have a list of 4800 numbers in a
column divided by groups of 5 within a larger group of 80. I need to
rearrange them in a second column with a different order but with a pattern.
Each group of five consecutive numbers are separated by a jump of 6 numbers
up to 75, starting at number ''1''. By using exactly the same pattern, start
this time with number ''6'' up to 80. The same pattern is repeated from 81 to
160, ... up to 4800.

I'm not an expert. Is there an efficient way to rearrange these numbers? Any
help would be great!

In other words, in column A, you have numbers from 1 to 4800. In column B, I
need the numbers to be in the following order:

A B

1 1 1st group of 80
2 2
3 3
4 4
5 5
6 11
7 12
8 13
9 14
10 15
11 21
12 22
13 23
14 24
15 25
16 31
17 32
18 33
19 34
