Query for normalized Google Sheet table
I want to normalize following table in Google Sheet:
| Process | Tool A | Tool B |
|---|---|---|
| Process 1 | Tool 1 | Tool 2 |
| Process 2 | Tool 1 | |
| Process 3 | Tool 2 | Tool 3 |
into the following 1NF table:
| Process | Tool A | Tool B |
|---|---|---|
| Process 1 | Tool 1 | |
| Process 1 | Tool 2 | |
| Process 2 | Tool 1 | |
| Process 3 | Tool 2 | |
| Process 3 | Tool 3 |
There are various options (Google Sheets QUERY() function, etc.).
Solution
You may try:
=reduce(A1:B1,B2:C,lambda(a,c,vstack(a,if(c="",tocol(,1),{index(A:A,row(c)),c}))))
