Usage Of Bool Function In Power Automate

Introduction

In Power Automate, at times we need to take decisions based on Boolean value, it could be string or Boolean value. As an example, the Power outage variable with true value is considered for demonstration and then the Bool function is used for condition validation.

Step 1

Login to the required Power Apps environment using URL make.powerapps.com by providing username and password and click on Flows on the left-hand side as shown in the below figure.

Step 2

After step 1, Click on New Flow and select instant cloud flow and provide the trigger as Manually trigger a flow and click on Create as shown in the below figure.

Step 3

After step 2, name flow as Bool Function and take initialize variable and name it as Set Variable Power Outage with the following fields

Name : Power Outage
Type : String
Value : true

as shown in the below figure.

Step 4

After step 3, take condition branch and name it as Verify Power Outage value is true string value with the following condition

Condition : variables(‘Power Outage’)
operator : is equal to
value : true

as shown in the below figure

Step 5

After step 4, in the yes part take a compose variable and name it as Power Outage exists in the given area and provide

Input value

Power Outage in the given area and the value is @{variables('Power Outage')}

As shown in the below figure

Step 6

After step 5, in the no part take another compose operation and name it as Power Outage Does not exist in the given area and provide

Input value

Power Outage Not Exists in the given area and the value is @{variables('Power Outage')}

as shown in the below figure.

Step 7

After step 6, take compose variable and name it as Pass Power Outage Variable to bool function and provide bool function with the syntax

bool(value : any)

with value like below

Input : bool(variables('Power Outage'))

And click on ok / update as shown in the below figure.

Step 8

After step 7, take a condition variable and name it as Verify Power Outage value is true (bool) value and provide

Condition : @outputs('Pass_Power_Outage_Variable_to_bool_function')
Operator : is equal to
Value : true

as shown in the below figure.

Step 9

After step 8, go to yes condition and take a compose action and name it as Power Outage exists in the given area - bool function and provide

Input : Power Outage in the given area and the value is @{outputs('Pass_Power_Outage_Variable_to_bool_function')}

 shown in the figure.

Step 10

After step 9, go to no condition and take a compose action and name it as Power Outage exists in the given area - bool function and provide

Input : Power Outage does not exist in the given area and the value is @{outputs('Pass_Power_Outage_Variable_to_bool_function')}

 shown in the figure.

Step 11

After step 10, you can see the results with string true condition flow moved to false part as shown in the figure.

Step 12

After step 11, you can see the results with the bool function true condition flow moved to the true part as shown in the figure.

Note

1. Make sure to save and run the flow whenever you try expressions.
2. MS documentation is found here

Conclusion

In this way, we can use the bool function to work on conditions.
