Hello all,

How can i traverse through this json object to grab the values i need which are all of them. I have the first one with:

first(body('Parse_JSON')?['ResultSets']?['Table1'])['item1'] in a compose action, how can i keep nesting through to get the others?

Thanks

{

"OutputParameters": {},

"ResultSets": {

"Table1": [

{

"item1": 253

{

"item2": 985

{

"item3": 3159

{

"item4": 3712

}

]

}

Hi @mmattar

You can directly use the parse json action to do this:

I stored the json in an array object for the source to the parse json action. You can directly bass the body/ output of previous action here. Click on generate schema and enter the sample payload and it will generate a schema for you. Based on that you will be able to access teh keys as dynamic content then.

Hope this Helps!

Hey @mmattar

Can you share a screenshot of the flow? Can you confirm the schema has been entered correctly and generated in the JSON action. Also, what is the consecutive action that you have in the flow? If you could share a screenshot it would be easier to identify the issue and assist you with this.

Hope this Helps!

Hey @mmattar

Note that you can only pass strings in the Respond to PowerApps or Flow action and the schema that you generated has array and objects of integers (strings). And to choose even one value, it would put the action in apply to each and you cannot do that for the respond action.

Based on the data you want to pass, you can add a compose action or a variable to store the data and then pass it to the respond action:

ok so this is what i am getting back to powerapps, i tried creating a variable for each item, but it seems as if the apply to each control puts all the items in each variable, how can we seperate each item in its own variable

Hi @mmattar

Since you are returning the response as a string, then you might want to perform manipulations in a way that it extracts the value out of it.

Expressions:

1st Item: Substitute(Last(FirstN(Split(var1.test,"{"&Char(34)&"Lunch"&Char(34)&":"),2)).Result,"}","")

2nd Item: Substitute(Last(FirstN(Split(var1.test,"{"&Char(34)&"Lunch"&Char(34)&":"),3)).Result,"}","")

3rd Item: Substitute(Last(FirstN(Split(var1.test,"{"&Char(34)&"Lunch"&Char(34)&":"),4)).Result,"}","")

4th Item: Substitute(Last(FirstN(Split(var1.test,"{"&Char(34)&"Lunch"&Char(34)&":"),5)).Result,"}","")

This will work in a way, you need to update the highlighted part with the index you want to get + 1.

Else, you could use the Response action (a premimum connector and starightaway pass the json and parse it in PowerApps then)

Hope this Helps!

Thanks for all this help, just one more question.

Substitute(Last(FirstN(Split(var1.test,"{"&Char(34)&"Lunch"&Char(34)&":"),2)).Result,"}","")

In the area i have highlighted red, this is where i put my variable that holds the string of the values i got from the json. but i keep getting that this expression is invalid, here is my expression

Substitute(Last(FirstN(Split(variables('leaks'),"{"&Char(34)&"Lunch"&Char(34)&":"),2)).Result,"}","")

Hey @mmattar

Can you share how you are creating this variable in PowerApps (the expression i shared is for powerapps). Also, variable('leaks') format is used on expressions for Flow. Here, in powerapps, you directly need to pass the variable name:

Substitute(Last(FirstN(Split(leaks.stirngname,"{"&Char(34)&"Lunch"&Char(34)&":"),2)).Result,"}","")

leaks is a variable created in powerapps to store the response returned by flow, stringname is the name of the variable from Flow.

Hope this Helps!
