How to Declare (Dim) and Set VBA Variables (use data types correctly)

Join 400,000+ professionals in our courses here 👉 https://link.xelplus.com/yt-d-all-cou... It’s best practice to declare your Excel VBA variables before you use them. Declaring variables means that you give VBA a heads up that it needs to free up some memory space for your variables which will in most cases be less than the default. That's why it's important to understand the concept of data types and how much memory space each of these types will take. The less memory you allocate to a variable, the faster your code will run. I show the range associated to each data type - such as numbers, text, date, currency etc in the video. 🎓 Get access to the full course here: https://www.xelplus.com/course/excel-... Key Highlights: - Default Data Type: By default, VBA assigns the data type called "Variant," which adapts based on the data it holds, leading to larger memory consumption. - Memory Efficiency: Different data types consume varying amounts of memory. For instance, a "Byte" takes up only one byte of memory, while a "Variant" uses around 16 bytes. - Data Type Ranges: Each data type has a specific range it can handle, which becomes crucial in scenarios where the data exceeds that range. - Common Data Types: Explore popular data types like "Byte," "Integer," "Long," "Boolean," "Double," "String," and "Object," each with its own purpose and memory footprint. - Variable Declaration: Learn how to declare variables using the "DIM" keyword, and understand naming conventions for variables. ★ Links to related videos: ★ Learn about Visual Basic Editor:    • Excel VBA tutorial for beginners: The...   Properties & methods in VBA:    • Learn How to Use Properties and Metho...   Blog Post: https://www.xelplus.com/excel-vba-dat... ★ My Online Excel Courses ★ ► https://www.xelplus.com/courses/ ➡️ Join this channel to get access to perks:    / @leilagharani   👕☕ Get the Official XelPlus MERCH: https://xelplus.creator-spring.com/ 🎓 Not sure which of my Excel courses fits best for you?
