In Google Sheets, how can I achieve the following “unwinding” of rows in a table that contains columns with multi-valued data:
| Column A | Column B, multivalued |
|---|---|
| First | A,B |
| Second | C,D |
It transforms the above to:
| Column A | Column B, multivalued |
|---|---|
| First | A |
| First | B |
| Second | C |
| Second | D |
How can I do this easily and quickly without having to manually split the data one row by one row?
