Transpose Groups Of Data Where Each Group Is A Different Size

way to transpose groups of data where each group is a different size. To clarify, my data looks like this (all one column):

data 1
data 2
data 3

data 4
data 5

data 6

data 7
data 8
data 9
data 10

and I would like to get it to look like
data 1 data 2 data 3
data 4 data 5
data 6
data 7 data 8 data 9 data 10

That is, to transpose each group of rows before a space.
