UiPath Variables: Types, Properties, and Variable Scope

In Moder world, UiPath or other RPA tools provides a vital part in automating repetitious and tedious tasks to make them easier and more accurate, and more effective for business processes. While using UiPath you’ll need to use UiPath variables. Variables are used to store data which allow you to manipulate and can be used on different processes.

On this page, we are going to take you on a trip to discover the power of UiPath Variables. You will learn all about what they are, the different types available, and how to use them in your automation process. So get ready to start your Automation process with Variables.

What are UiPath Variables

Variables are storage spaces that can be used to hold multiple data entries( values) of the same data type. In Uipath Variables are used to store values that they can use later or across their automation Process. All variables are unique which means you cannot create two variables of the same name. For Example:

EmailAddress can be a variable that holds the value “sample@rpatutorials.com”. like these, variables can be used to store multiple values such as Name, Age and etc.

The value of each variable can be changed through an external input, data manipulation, or passing from one exertion to another and each variable is unique

Properties of UiPath Variables

Now let’s understand some of the properties of variables.

How to Create Variables in UiPath Studio

You can create or declare a variable by following any one of the below methods in your uipath studio:

1. From the Variables Panel

You can easily declare variables from the variable panel:

• Click on the Variable section.
• Now click an empty field to make a new variable in your uipath studio.

2. By Right Click In the Input Field of an Activity

You can declare a variable directly within the activity in uipath studio:

• Click an activity in which you want to create a variable.
• Right-click and select “create a variable” to create a variable and set its datatype, scope, and default value.

3. By using a Keyword Shortcut

You can also create variables using keyboard shortcuts such as Ctrl + K

• Click on the text field of any activity
• Then press Ctrl + K and now you can see “Set Var” and type your variable name to set it as a variable.

Types of UiPath Variables

As now you have familiarised yourself with variables, now we will go through UiPath Variable types of variables used in UiPath for your automation process.

• Number Variables
• Text Variables
• Array Variables
• True or False Variables
• Data Table Variables
• Date and Time Variables

Text Variables

A UiPath variable in String or text is used to store values that are in the form of text or string. These variables are able to store values such as user names, employee names, or any other string queries. Example:

True or False Variables

This variable is also known as a boolean variable. It can store two values either False or True. This variable helps you to make a decision Flowchart. Example

Sample_Number=30
if Sample_Number greater than or equal to 0 ---> "Positive Number " ( Statement is True )
If Sample_Number Less than o --> "Negative Number " ( Statement is False)

Number Variables

This variable is also known as int32 or Integer variable. This variable is able to store numeric values. Example: Age, Year, etc.

• Int32: Used to store values like 10, 45, 89
• Long: Used to store values like 10, 45, 89
• Double: Used to store values like 10, 45, 89

Array Variables

Array Variables are able to store more than one value in a single variable. It can have multiple subfields and each field has its own values. In Array variables, you have to choose which data type values are used in these variables.

Date and Time Variables

UiPath Variable date and TIme variable allow you to store values of dates and times. Dates are in “dd/mm/yyyy” (Date/Month/Year) format and Times are in “hh:mm: ss” (Gour:Minute: Second) this format

Data Table Variables

Data Table Variables are mainly used to store a large number of values. These are used in web scrapping, excel automation to store multiple data in rows and columns. These variables have the capacity to store huge values compared to other variables.

Proprietary Variables

1. GenericValue Variables: Generic value variables in uipath can store values of data including numbers, text, dates, and arrays. These variables are automatically converted to other datatypes based on their requirements. So you don’t need to use data type conversion methods and uipath global variables.
2. QueueItem Variables: These variables are able to store queue items in uipath studio.

Browser Variables

UiPath Browser Variables are the variables used in browsers to store values in web automation. To create a browser variable you can either use the variables panel or use a keyboard short key. You can use browser variables to set input and output values.

UiPath Variables Data Type Conversion

As now you have familiarized yourself with uipath data types now we will check if you can convert from each datatype to another datatype that can be used on your uipath automation. During automation, there may be some cases where you have received incorrect datatype values, so in that use case, you can use these conversion methods.

Conclusion

Till now we have discussed UiPath Variable Scope, and also check how to perform data type conversion in your uipath studio. You can use these variables in UiPath Studio to store values such as list, string, date, double and null, or empty values.
