Posted on by vnguyen1

below is my parsejason schema:

{
"type":"object",
"properties":{
"id":{"type":"string"},
"keywords":{"type":"array",
"items":{
"type":"object",
"properties":{
"keyword_id":{"type":"string"},
"text":{"type":"string"}
}
}
}
}
}
}

======================

output result:

{
"images": [
{
"id": "1135303410",
"keywords": [
{
"keyword_id": "60494",
"text": "Education",
"type": "Unknown",
"relevance": null
},
{
"keyword_id": "74709",
"text": "Pharmacy",
"type": "Unknown",
"relevance": null
},
{
"keyword_id": "60004",
"text": "People",
"type": "Unknown",
"relevance": null
}}

Goal : combine all the texts for each return keyword into a string as

combinekeywords: 'Education,PharmacyPeople'.

Anyone has any sugesstion or idea how to get this done ? Thanks in advance

Hi @vnguyen1,

Your output and JSON Schema have some parenthesis errors, you can use the data I corrected below to test:

Output:

{ "images": [ { "id": "1135303410", "keywords": [ { "keyword_id": "60494", "text": "Education", "type": "Unknown", "relevance": null }, { "keyword_id": "74709", "text": "Pharmacy", "type": "Unknown", "relevance": null }, { "keyword_id": "60004", "text": "People", "type": "Unknown", "relevance": null } ] } ] }

Schema:

{ "type": "object", "properties": { "images": { "type": "array", "items": { "type": "object", "properties": { "id": { "type": "string" }, "keywords": { "type": "array", "items": { "type": "object", "properties": { "keyword_id": { "type": "string" }, "text": { "type": "string" }, "type": { "type": "string" }, "relevance": {} }, "required": [ "keyword_id", "text", "type", "relevance" ] } } }, "required": [ "id", "keywords" ] } } } }

Step 1: Put the data into the compose, then use the Parse JSON action to get the output of JSON.

Step 2: Initialize a String variable named comebinekeywords.

Step 3: Add Append to String variable action to put the "text" + "," into it.

Step 4: Process the last "," character use the expression:

substring(variables('combinekeywords'),0,sub(length(variables('combinekeywords')),1))

Please have a try, I hope it can help you.
