I recently found I needed to remove non-alphanumeric characters in Google Sheets. I had a column of text containing business names which I needed to format as URL friendly equivalents. For example, I needed to turn these:
- My Business Name
- Derek’s World of Fish!
- Jane & Janet’s Pieland
I achieved this by added the following formula into the top cell of a blank column. This assumes the names you need to format are in the fist column of the spreadsheet
=ArrayFormula( lower(REGEXREPLACE( A2:A , "([^A-Za-z0-9]+)|(---)" , "-" ) ))
