Google Sheets isn’t Excel - don’t expect everything to work the same. Start with Google’s built-in templates, they’re actually solid for learning different use cases. The real-time collaboration is the biggest difference I noticed when I switched. You’ve got to experience it yourself, can’t just read about it. Learn IMPORTRANGE and QUERY functions early - they’re incredibly powerful once you get them. My biggest mistake? Trying to copy my Excel workflows exactly instead of embracing the cloud-native approach.
