The Power of Protection
Locking columns isn't just about security; it's about streamlining your workflow. By designating protected areas, you can focus your attention on the editable sections, reducing errors and improving efficiency. Think of it as building a strong foundation for your data – a secure base that allows for flexible manipulation without compromising integrity.
