Multiple column data into one line ?

Hi,

I'm wondering if someone could help me with one or two things:

I have a data set arranged in column form, but I'm wondering if it is possible to combine them into one cell.
For example, if in column 1, I have the following numbers (let's say from cells B5 to B10): 56 | 58 | 123 | 200 | 500 | 700, is there a formula that would let me combine them all so as to look like the following?

56, 58, 123, 200, 500, 700 in ONE cell?

Much appreciated.
