Power Automate Fundamentals # 52: Usage of Take Function in Power Automate

Introduction:

In Power Platform, at times we must take few elements from an Array or few characters from a given string. In these scenarios, Take function in Power Automate can be used. As an example Employees String Array and Employee Name String variable were used to explain this behaviour.

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 the flow as Take  Function and take a parallel branch and one side of branch take an initialize variable and name it as Set Employees Array and provide values

Name: Employee Names

Type: Array

Value: [“Venkat”,”Polisetty”,”Subba Rao”]

as shown in the below figure.

Step 4:

After Step 3, to the other side of  parallel branch take another initialize variable and name it as Set Employee Name and provide values

Name: Employee

Type: String

Value: VenkataSubbaraoPolisetty

as shown in the below figure.

Step 5:

After Step 4, now under Set Employees Array step take a compose action and name it as Get Employee Details With Take Function and provide the inputs with take  function which Returns the elements in the array/string starting at index Count syntax

take(collection: array|string, count: integer)

as

Inputs : take(variables(‘Employee Names’),2)

as shown in the below figure.

Step 6:

After Step 5, now under Set Employee Name take a compose action and name it as Get Employee Name With Take Function and provide the inputs as

Inputs : take(variables(‘Employee’),7)

as shown in the below figure.

Step 7:

After Step 6, save and test the flow and observe the results as shown in the below figure.

Note:

  1. Make sure to save and run the flow whenever you try expressions.
  2. Make sure to provide input array in proper acceptable format of string array.
  3. Also use double quotes for the elements in the array.
  4. Microsoft documentation found here.
  5. For integer type variables as well, take function can be used.

Conclusion: In this way we can use Take function in power automate to achieve customer functionality.
