Skip to content Variables and Data Types
Introduction
In Visual Basic for Applications (VBA), variables are used to store data in memory. Before you can use a variable, you need to declare it by specifying its name and data type. In this guide, we will walk you through the process of declaring variables and using different data types in VBA.
Prerequisites
Before you begin, make sure that you have Microsoft Excel installed on your computer. You will also need a basic understanding of programming concepts.
Declaring Variables
To declare a variable in VBA, you need to use the Dim statement followed by the variable name and data type. Here are some examples:
Dim myString As String
Dim myNumber As Integer
Dim myBoolean As Boolean
Dim myByte As Byte
Dim myCollection As Collection
Dim myCurrency As Currency
Dim myDate As Date
Dim myDecimal As Decimal
Dim myDictionary As Object
Dim myDouble As Double
Dim myInteger As Integer
Dim myLong As Long
Dim myLongLong As LongLong
Dim myLongPtr As LongPtr
Dim myObject As Object
Dim mySingle As Single
Dim myVariant As Variant
n the above example, we have declared variables with different data types. myString is a string variable that can store text values. myNumber is an integer variable that can store whole numbers. myBoolean is a boolean variable that can store True or False values. myByte is a byte variable that can store values from 0 to 255. myCollection is a collection variable that can store a group of related objects. myCurrency is a currency variable that can store monetary values. myDate is a date variable that can store dates and times. myDecimal is a decimal variable that can store decimal values with up to 28 places to the right of the decimal point. myDictionary is an object variable that can store key-value pairs. myDouble is a double variable that can store large numbers with decimals. myInteger is an integer variable that can store whole numbers from -32,768 to 32,767. myLong is a long integer variable that can store whole numbers from -2,147,483,648 to 2,147,483,647. myLongLong is a long long integer variable that can store whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 (valid on 64-bit platforms only). myLongPtr is a long integer on 32-bit systems and long long integer on 64-bit systems that can store whole numbers from -2,147,483,648 to 2,147,483,647 on 32-bit systems and -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 on 64-bit systems. myObject is an object variable that can store any object reference. mySingle is a single-precision floating-point variable that can store numbers with decimals. myVariant is a variant variable that can store any type of data.
Conclusion
Understanding variables and data types is essential for anyone looking to automate tasks or perform complex calculations using VBA code. By following these steps and declaring variables with appropriate data types for your use case in VBA programming language you will be able to write efficient code!
