Let’s prepare the GUI

The GUI of this tool is very simple. As shown in the image, just one sheet with necessary headers and columns is sufficient. In this example, for a given Domain, the tool will scrape Registrant Name and Registrant Organization. To allow users to run the macro, create a button on the same sheet.

Let’s make it functional

Paste the script into a new module and attach the sub “whoismacor” to the button we created on Sheet1.

Let’s test it

Add domains in the Column A and run the macro. Values will be displayed on respective columns.

Modify it

As of now the tool shows 2 headers i.e., Registrant Name and Registrant Organization. You can customize the tool to fetch any of following header.
