Convert an array to string in Power Automate (MS Flows)

converting an array value to a string using Power Automate out of the box function.

 

"how to convert an array to string" in MS Flows.

 

Basically, we can use "split" function to convert an array into string but we may end up having extra column to the last value. To remove that we have to use another expression which checks for the string length and removes the last character [

substring(variables('varListOfRequestIDs'),0,sub(length(variables('varListOfRequestIDs')),1)) ].

 

To avoid the whole cumbersome process, we can leverage Power Automate's simple and out of the box function - join

 

Here is an to show how can we convert an array to string. for instance let's consider, we have an array [796759,933436,926050,1388108,762632,764554]. But as per the requirement, we need to convert it to string and send that value as 796759,933436,926050,1388108,762632,764554. 

varListOfRequestIDs = [796759,933436,926050,1388108,762632,764554]

varStringListOfRequestIDs : join(variables('varListOfRequestIDs'),',') gives us 796759,933436,926050,1388108,762632,764554

@ChristianAbata Yeah, I agree. But in the example I have given, I need to have an array to convert as string from [1,2,3,4,5] to 1,2,3,4,5 which altogether changes its data type and the value with out brackets. But when I tried with sting(variables('varArray')), it was giving me the value as string but with brackets. So, I thought of sharing this with you all and might help.

 

feel free to add your thoughts to this.

 

function: joinfunction: joinfunction : stringfunction : string

ok @krishnags  please do this to delete the last and the firts character from string.

substring(outputs('Compose'),0,sub(length(outputs('Compose')),1))

 

substring(outputs('First'),1,sub(length(outputs('First')),1))

@ChristianAbata yeah, but if we go with JOIN, we can eliminate  substring(outputs('Compose'),0,sub(length(outputs('Compose')),1))  this finding length, getting substring and all. simply use JOIN and get the things done 🙂

shure @krishnags  so this solve your problem or not friend jejeje
