Collect JSON string into columns

Posted on by CU24061526-1

Good evening,

I have this JSON string returned from Microsoft Automate and I'd like to turn the results into columns. The sample return string looks like this:

{"__metadata":{"id":"123","uri":"api/Items(1)","etag":"\"1\"","type":"SP.Data.SP.Items"},"Title":"TitleVal","Column1":"Column1Val","SomeOtherCol":"SomeOtherColVal","UserID":"1697"}

I know I only want the string just after the first "}" and so I generate this code:

Last(FirstN(Split(sampleString.Text, "}"), 2)).Result

From here, what is the best method to converting the result from this:

into a collection with this:

Title	Column1	SomeOtherCol	UserID
TitleVal	Column1Val	SomeOtherColVal	1697

The logic that I think may work is to to not even do a split yet and conduct a find for each field and then split after to find the values for it. I'm just bouncing ideas here and see if I'm working in the right direction.

EDIT: I got this and it's giving me the correct results but I'm kinda hardcoding the number of spaces to retrieve. There's got to be a better / dynamic way.

Substitute(First(Split(Mid(sampleString.Text, Find("SomeOtherCol", sampleString.Text) + 13 +1), ",")).Result, Char(34), Blank())

EDIT #2: I think I am going to settle with this logic:

Substitute(Last(Split(First(Split(Mid(sampleString.Text,Find("Title",sampleString.Text)),",")).Result,":")).Result, Char(34), Blank())

If you have control over the Power Automate Flow that your app is using, you could return the JSON object instead of the result string so your app can consume the result as a collection/object without parsing it. Try adding a Response action (Premium) and place your JSON text into the Schema builder.

hehe, unfortunately I am not allowed to consume any premium connectors, but taking a bit of your idea, I might sanitize the data before consuming it inside PowerApps.

Hi @MrNguyen ,

Have you solved your problem?

Based on the needs that you mentioned, actually, you could consider convert the JSON String into the JSON Table, then pass the JSON Table back to your canvas app.

I have made a test on my side, please consider take a try with the following workaround:

Flow's configuration as below:

Add a "Response" action at the bottom of your flow, set the Body field to following:

json(variables('JSONString'))

Note: Use the json expression to convert the JSON String into JSON Table

Set the "Response Body JSON Schema" field to following:

{ "type": "object", "properties": { "__metadata": { "type": "object", "properties": { "id": { "type": "string" }, "uri": { "type": "string" }, "etag": { "type": "string" }, "type": { "type": "string" } } }, "Title": { "type": "string" }, "Column1": { "type": "string" }, "SomeOtherCol": { "type": "string" }, "UserID": { "type": "string" } } }

App's configuration as below:

Set the OnSelect property of the "Retrieve Collection" button to following:

ClearCollect(TableResult, 'PowerApp->Initializevariable,Response'.Run())

The TableResult collection would look like below:

Please check and see if the following blog would help in your scenario (Pass table from flow to canvas app):

https://powerapps.microsoft.com/en-us/blog/return-an-array-from-flow-to-powerapps-response-method/

Please take a try with above solution, then check if the issue is solved. If the solution above is helpful in your scenario, or you have solved your problem, please consider go ahead to click "Accept as Solution" to identify this thread has been solved.

Best regards,

@v-xida-msft ,
Thanks very much for this! I have yet to test this out since it uses a premium connector but I will save it and attempt it later if company allows me hehehe.

Hey! Are there any non-premium work-arounds for this? Alternatively, importing csv or excel file in stead of a json could work for me as well.
