how to combine all texts in json schema into one string using flow.

[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.

below is the json that i tried to each ID..

example for this run; i have total 8 downloaded asset on that day. i send these ID to search for theri keywords.. after that combine them by your guildline sucessfully. 

However, when i tried to put these in the loop. the 1st asset get the correct combinekeyword. however, the 2nd asset .. the combine keyword are the same as 1st keyword, it did not update the value ... 

this is 1st asset : correct value :" Education,...."

this is 2nd asset : the output keep the same as 1st asset ... "Education,.." . it should be "people,..."

{

"type": "object",

"properties": {

"result_count": {

"type": "integer"

},

"downloads": {

"type": "array",

"items": {

"type": "object",

"properties": {

"date_downloaded": {

"type": "string"

},

"id": {

"type": "string"

}

},

"required": [

"date_downloaded",

"id"

]

}

}

}

}

Please advice

@v-litu-msft 

i found a solution. just set variable to reset combinekeyword to NULL before the loop run. it fixed the issue
