With our pre-defined extractors (PDE), all the columns and the names of the columns are pre-set by default. Usually named after the same title on the webpage. Some users want to change the names of the column headers to something more meaningful or drop some columns which might not be useful to them.
Now you have the option to rename and customize this. Follow the below steps to use this feature
From your extractors page, switch your PDE to Advanced Mode, then go to Columns
In the Custom Column Names rename the original column with something more meaningful to you
Click the Save button on all the column names you would like to appear on your data output
