Query a count of unique attributes in a table - google-sheets

Question

I have a table like this:
+--------+-------+--------+-------+
| attr1 | attr2 | attr3 | attr4 |
+--------+-------+--------+-------+
| purple | wine | clear | 10.0 |
| red | wine | solid | 20.0 |
| red | beer | cloudy | 10.0 |
| purple | ale | clear | 34.0 |
| blue | ale | solid | 16.0 |
+--------+-------+--------+-------+
that i want to transform like this:
+--------+-------+-------+-------+-------+
| | attr1 | attr2 | attr3 | attr4 |
+--------+-------+-------+-------+-------+
| purple | 2 | | | |
| red | 2 | | | |
| blue | 1 | | | |
| wine | | 2 | | |
| beer | | 1 | | |
| ale | | 2 | | |
| clear | | | 2 | |
| solid | | | 2 | |
| cloudy | | | 1 | |
| 10.0 | | | | 2 |
| 20.0 | | | | 1 |
| 34.0 | | | | 1 |
| 16.0 | | | | 1 |
+--------+-------+-------+-------+-------+
This pivoted or cross-table will show me the count of each attribute value in their respective columns.
How do i use the Google Query language to display such a cross-table?

Answer 1

Well if the data were laid out in two columns it would be straightforward e.g. for something like this
Attrib Column
Red 1
Red 1
Green 1
Blue 1
Beer 2
Ale 2
Ale 2
you could use a query like
=query(A:B,"select A,count(A) where A<>'' group by A pivot B")
So the problem is to organise OP#s data into two columns.
This can be done by what is by now a fairly standard split/join/transpose technique
=ArrayFormula(split(transpose(split(textjoin("|",true,if(A2:D="","",A2:D&" "&column(A2:D))),"|"))," "))
Giving
You could either run the query on the result of this or combine the two like this
=ArrayFormula(query({"Attrib","Number";split(transpose(split(textjoin("|",true,if(A2:D="","",column(A2:D)&"-"&A2:D&" "&column(A2:D))),"|"))," ")},"Select Col1,count(Col1) group by Col1 pivot Col2"))
I have joined the column number to the attribute e.g. 1-blue so that it sorts into the right order. If you don't like it, you could get rid of it using regexreplace.
Edit
Slightly shorter formula - I didn't need to put the headers in separately:
=ArrayFormula(query(split(transpose(split(textjoin("|",true,if(A2:D="","",column(A2:D)&"-"&A2:D&" Attr"&column(A2:D))),"|"))," "),
"Select Col1,count(Col1) group by Col1 pivot Col2",0))
Edit 2
I was being a bit thick there, should have used first row of OP's data as attribute labels instead of column numbers
=ArrayFormula(query(split(transpose(split(textjoin("|",true,if(A2:D="","",column(A2:D)&"-"&A2:D&" "&A1:D1)),"|"))," "),
"Select Col1,count(Col1) group by Col1 pivot Col2",0))
Edit 3
Should have chosen a better pair of delimiters
=ArrayFormula(query(split(transpose(split(textjoin("😊",true,if(A2:D="","",column(A2:D)&"-"&A2:D&"🍺"&A1:D1)),"😊")),"🍺"),
"Select Col1,count(Col1) group by Col1 pivot Col2",0))
