I have data sets that got put all together in two columns. In the first column I have the x values just repeating for each new set of data with the corresponding y values in the second column. I want to leave the first set of x values in the first column and then get each set of y values moved to their own column. I am using Excel 2013.

the data looks something like this:

10 302
11 489
12 367
10 100
11 268
12 187
10 78
11 89
12 99

And I need it to look like this:

10 302 100 78
11 489 268 89
12 367 187 99

Any help would be greatly appreciated!
