Execute Macro Output Query

Help Activities

Hey guys!

Basically I have a Workbook with a macro that I am executing, and passing in VAR parameters through Uipath.

In the VB Code I am then setting Values from the workbook to Variables but I can’t seem to pass these out to UiPath from the execute macro activity.

Wondering how do you retrieve output from this activity, as any time I use it, the output is null.

Many Thanks

Execute Macro activity will give output of type Object.

Is Execute Marco activity executing properly on that excel file ?

Hi @lakshman Yes the activity works perfectly and executes the macro in the Workbook, but doesn’t give any output… Should I have something in the VB Code of the Macro to give output?

@Kyleb91

Yes it should be there in your Macro code. Then only it will give output else not.

Hi @Kyleb91 ,

Can you show me your macro function?

Are you returning value from macro function?

Sub CRT_Paste(VAR1 As String, VAR2 As String, VAR3 As String, VAR4 As String)
    

        Range("D19") = VAR1
        Range("E19") = VAR2

        
        VAR3 = Range("R19")
        VAR4 = Range("L5")
        
        
End Sub

Basically I want to Return VAR3 and VAR4 back to UiPath from this Execute Macro Activity, via this macro code.

Hi @Kyleb91 ,

Try like this

Sub CRT_Paste(VAR1 As String, VAR2 As String, VAR3 As String, VAR4 As String) As String

    Range("D19") = VAR1
    Range("E19") = VAR2

    
    VAR3 = Range("R19")
    VAR4 = Range("L5")
    CRT_Paste = VAR3

End Sub

Try first for Var3

Hi @Kyleb91

Procedures cannot return a value in VBA, you have to use function for that.

FUNCTION CRT_Paste(VAR1 As String, VAR2 As String, VAR3 As String, VAR4 As String) as string
    

        Range("D19") = VAR1
        Range("E19") = VAR2

        
        VAR3 = Range("R19")
        VAR4 = Range("L5")


        CRT_Paste = VAR3
        
End function

Thanks

Brilliant, I thought that may have been the issue…

May I ask you how I would call on the value in UiPath form the output object after this? For VAR3

@Kyleb91 have you create a variable for output in execute macro, and check the value in message box.

Thanks

Thanks I have got VAR3, but how do I pass out VAR3 AND Var4?

You can put like this in VBA,

FUNCTION CRT_Paste(VAR1 As String, VAR2 As String, VAR3 As String, VAR4 As String) as string
    

        Range("D19") = VAR1
        Range("E19") = VAR2

        
        VAR3 = Range("R19")
        VAR4 = Range("L5")

CRT_Paste = Var1 & "," & Var2 & "," & Var3 & "," & Var4

End function

And after getting the output from UiPath use split function to split the values by comma,like this, it will give an array of values.

arrVal - arrray of String (system.string)

arrVal = Output.split(","c)

Var1 = arrVal(0)
Var2 = arrVal(1)
Var3 = arrVal(2)
Var4 = arrVal(3)

If you want all 4 values

Thanks

Example:

Public Function test() As String
    test = "1"
End Function

Function name is test, so with the same name test with value “1” will be returned

Returning multiple values we can do when complex datatypes (e.g. dictionary) is not supported ( and we do not want use arrays) by returning a serialized string e.g. {{“Key1”,“Val1”},{“Key2”,“Val2”}}

Afterwards we can easy bring this again in a dictionary

Thanks! Although the below doesn’t seem to be accepted by VBA, do I need to change the CRT_Paste as String to something else first?

CRT_Paste = Var1 & “,” Var2 & “,” Var3 & “,” Var4

15

Hey Peter, thanks again! :smiley:

Could you show your above code with an example of 2 VARs being passed out? Like the dictionary you say.

Many Thanks

16

{{“Key1”,“Val1”},{“Key2”,“Val2”}} would be the string

17

@Kyleb91 try like this, typing in mobile so had some mistakes

FUNCTION CRT_Paste(VAR1 As String, VAR2 As String, VAR3 As String, VAR4 As String) as string
    

        Range("D19") = VAR1
        Range("E19") = VAR2

        
        VAR3 = Range("R19")
        VAR4 = Range("L5")

CRT_Paste = Var1 & "," & Var2 & "," & Var3 & "," & Var4

End function

Thanks

18

Thanks! But…

CRT_Paste = Var1 & “,” & Var2 & “,” & Var3 & “,” & Var4

This still does not work…

19

@Kyleb91 it should work, I just tested it, do you get any errors.

Thanks
