Import columns to existing OpenRefine project
How do I add a column from an external .csv file to an existing project? I tried to find the solution online, but I wasn't successful.
Using the file you provided, I did this in less than one minute. I had a project, with one column: . If you know a little Python, try Jython. Edit Column > Add column based on this column and chose Language : Jython like this: import csv #we are going to use DictReader to transform our imported rows into dict, #so we can latter just refer to the column we want by its key i.e header rows = csv.DictReader(open('/home/yourusername/Downloads/example.csv'), delimiter=",") for row in rows: return row['Comprar'] #'comprar' is the header of the column i want
