Spreadsheets are infinitely flexible, especially in Excel, which can be used to automate simple tasks and enhance productivity. Macros, a code that automates work in a program, can add features and enhancements to help accomplish specific goals quickly with just a click of a button. The Visual Basic Editor is where macros are edited and stored, and it offers two main ways to create them: recording actions or writing code manually. Recording macros is a simple way to get started, but writing code allows for more power and flexibility. By adding loops, logic, and automation, Excel macros can streamline work, automate repetitive tasks, and even make intelligent decisions on their own. While macros have limitations, such as being tied to the computer, they can be overcome with tools like Zapier, which connects Excel to hundreds of other apps for seamless integration.
