How to use Custom Types To Write Ultra Fast VBA code

One of the powerful features of VBA is the ability to create user-defined types. User-defined types, also known as custom types, are data structures that can hold multiple pieces of data of different data types. They allow developers to create their own data types that are tailored to the specific needs of their application.

By defining custom types, developers can organize related data into a single variable and manipulate it as a unit. This makes code easier to read, write and maintain, as it simplifies the code and reduces the risk of errors. User-defined types can be used to create complex data structures and objects that are not available in the built-in data types of VBA. This is especially useful when developing large-scale applications or add-ins that require custom data types to perform complex operations.
