Lesson

Scripts

  • Refine saves every change, every edit you make to the dataset in a file you can save on your machine.
  • If you had 20 files to clean, and they all had the same type of errors, and all files had the same columns, you could save the script, open a new file to clean, paste in the script and run it. Voila, clean data.
  - In the Undo / Redo section, click Extract, save the bits desired using the check boxes. 
  - Copy the code and paste it into a text editor. Save it as a .txt file.

To run these steps on a new dataset, import the new dataset into Refine, open the Extract / Apply section, paste in the .txt file, click Apply.
