I am new Open refine user and don't know how to code.
I would like to group multiple values of a column compared to an other column.
I have this file
ID 1 | ID 2 |
---|---|
ID1.1 | ID2.1 |
ID1.1 | ID2.2 |
ID1.2 | ID2.3 |
ID1.2 | ID2.4 |
ID1.2 | ID2.5 |
And i'd like to have this one :
ID 1 | ID 2 |
---|---|
ID1.1 | ID2.1;ID2.2 |
ID1.2 | ID2.3;ID2.4;ID2.5 |
The file got 150k lines and multiple columns
I tried to Add a new column based on the first column, but I don't how to group the values of the row1, row2, row3... of the second column based on the value of the first column.
Thank you for any answer
