Starting point: List of websites with 'junk' around the main domain (Ex. https://www.acme.com/home)
Ideal end state: 'Clean' view of the domain
Examples use cases: To identify duplicates, to match external lists to your Account database, to import to a 3rd party as a base list to find additional contacts (ie ZoomInfo)
Build and export an Account report. from Salesforce.com
Import to a Google sheet
File >> Import >> Upload >> Insert a new sheet
In a new column, add this formula to 'clean up' the domains:
=trim(REGEXEXTRACT(REGEXREPLACE(REGEXREPLACE(A2,"https?://",""),"^(w{3}\.)?","")&"/","([^/?]+)"))
Caveats:
