Believe it or not, I had the SAME exact problem. I don’t believe there IS a snap to fix this, BUT, you can use the script snap. That is what I did. AND, though I didn’t write it to be neat. If you tell it you are using a python program, you can pivotdata.py.txt (1.6 KB)
use my script. I was a dreamer, and my dream didn’t work. You might want to change the line:

in_doc[“_”+fieldsr[i]]=fields[i]

to

in_doc[fieldsr[i]]=fields[i]

tstack:

{}.extend($group.map(x => [x.Category, x.DataType]))

Thanks Stephen! 🙂
I’ll try this approach as well.

Indeed, there’s a Pivot snap, but that does the opposite of what you’re looking to do. Until such a snap exists, you can do this using a GroupByN snap and the expression language. If you add a GroupByN snap with a “Group Size” of zero, it will collect all of the incoming data into a single document. You can then follow that up with a Mapper that has this expression:

{}.extend($group.map(x => [x.Category, x.DataType]))

The extend() method will construct a new object containing the key/value pairs returned by the $group.map() call.

Here’s a screenshot:
