Code to slugify text. Mainly to use in google sheets.

slugify.js

function slugify(value) {
  /*
   * Convert the the vs in a range of cells into slugs.
   */
  slug = '';
  
  slug = value.substring(0, 30).toLowerCase();
  slug = slug.replace(/[^\w\s-]/g, '');
  slug = slug.replace(/\s+/g, '-');
  Logger.log(slug);
  
  return slug;
}

function test() {                 
    Logger.log(slugify("This is a very very very long text.This is a very very very long text.This is a very very very long text.This is a very very very long text."));
}
