Posted on by Rahul_skl

Hello everyone,

I have a json file in which i have value as key value pairs. I want the key to be the columns in excel file and the values for that key should be in rows. I am getting the error while parsing the json file .Can someone please help me in solving my issue. Please find the attached json file, and the workflows where i am getting error. i successfully extract the keys from json file and put it as columns in excel file but while writing the values for each keys in row i am getting an error . It seems like i cant upload the json file here so i took the screenshot of .jsonfile for reference in text format .

Hi @Rahul_skl ,

I think your trying to create a Config file flow. For this i have simpler solution than this.
Please find the below solution. Just change the config path.

4 th action is showing how you can call Config variables.

Please place the things in excel as shown below.

Code:
Please copy the below code to your flow.
SET Config_Path TO $'''C:\\Users\\Desktop\\Power Automate Desktop\\Config\\Config File.xlsx''' @@copilotGeneratedAction: 'False' Scripting.RunVBScript.RunVBScript VBScriptCode: $'''Set objExcel = CreateObject(\"Excel.Application\") Set objWorkbook = objExcel.Workbooks.Open(\"%Config_Path%\") Set objSheet = objWorkbook.Worksheets(\"Constants\") intRow = 2 \'start at row 2 since row 1 has column headers strOutput = \"\" Do While objSheet.Cells(intRow, 1).Value <> \"\" strKey = objSheet.Cells(intRow, 1).Value strValue = objSheet.Cells(intRow, 2).Value strValue = Replace(strValue, \"\\\", \"\\\\\") \'replace \\ with \\\\ strOutput = strOutput & \"\"\"\" & strKey & \"\"\": \"\"\" & strValue & \"\"\",\" intRow = intRow + 1 Loop strOutput = Left(strOutput, Len(strOutput) - 1) \'remove the trailing comma strOutput = \"{\" & strOutput & \"}\" WScript.Echo strOutput \'output to the console objWorkbook.Close False objExcel.Quit''' ScriptOutput=> ConfigAsJSON ScriptError=> ScriptError Variables.ConvertJsonToCustomObject Json: ConfigAsJSON CustomObject=> ConfigAsCustomObject Web.InvokeWebService.InvokeWebService Url: ConfigAsCustomObject['API Endpoint'] Method: Web.Method.Get Accept: $'''application/json''' ContentType: $'''application/xml''' ConnectionTimeout: 30 FollowRedirection: True ClearCookies: False FailOnErrorStatus: False EncodeRequestBody: True UserAgent: $'''Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.8.1.21) Gecko/20100312 Firefox/3.6''' Encoding: Web.Encoding.AutoDetect AcceptUntrustedCertificates: False ResponseHeaders=> WebServiceResponseHeaders2 Response=> WebServiceResponse2 StatusCode=> StatusCode2

Dear Deenuji,

I exacrly implemented my workflow watching this video only..you can even see all the steps are same but in my scenario i have only one curly braces in json file thats why the value under jsonascustomobject has no index values and its in tabular format so thats why i get this issue .I hope you understand what i meant and the error is because of that because it cant read the currentitem[currentkey] in line no.19 and in video at 8.30 .

Dear Visnu, Thanks for your response but i think my scenario is different and the procedures you suggested seems to be too complex for me. I didnt understand .All when i just etxract key from json file i am able to put those keys as columns in excel file but when i start writing the value for that key i could not as its give me an error and thats valid also because jsonobject is not a datatable. But I dont undertand how to read value for those key in second row in their respective columns. you can see the entire workflow of mine .

Hi @Rahul_skl ,

You can read value for those key in second row in their respective columns as shown in below image.
For example i have taken display message.

All I think there is some logic related to iterating through the key in jsonascustomobject which seems to be wrong for me.

Even you JSON don't have index we can still achieve your goal using .net scripts.
Please follow the below approach.

SET StrJsonstring TO $'''{ \"Invoice\": \"982309823-Rev.1\", \"Customer\": \"WWW>AVA-ALMS.DE\", \"Item\": \"skldjslkdl;sdjklsjd\" }''' Excel.LaunchExcel.LaunchUnderExistingProcess Visible: True Instance=> ExcelInstance Variables.CreateNewDatatable InputTable: { } DataTable=> DataTable Scripting.RunDotNetScript Imports: $'''System System.Collections.Generic System.Data''' Language: System.DotNetActionLanguageType.CSharp Script: $''' // Remove whitespace and {} jsonData = jsonData.Trim().Trim(\'{\', \'}\'); // Split by commas string[] parts = jsonData.Split(\',\'); // Create a DataTable dataTable = new DataTable(); // Add columns for each key foreach (string part in parts) { // Split key and value by colon string[] keyValue = part.Split(\':\'); // Remove quotes and trim string key = keyValue[0].Trim().Trim(\'\"\'); dataTable.Columns.Add(key, typeof(string)); } // Add a row with values DataRow newRow = dataTable.NewRow(); foreach (string part in parts) { // Split key and value by colon string[] keyValue = part.Split(\':\'); // Remove quotes and trim string key = keyValue[0].Trim().Trim(\'\"\'); string value = keyValue[1].Trim().Trim(\'\"\'); newRow[key] = value; } dataTable.Rows.Add(newRow);''' @'name:jsonData': StrJsonstring @'type:jsonData': $'''String''' @'direction:jsonData': $'''In''' @'name:dataTable': $'''''' @'type:dataTable': $'''Datatable''' @'direction:dataTable': $'''Out''' @dataTable=> DataTable Excel.WriteToExcel.WriteNamedCell Instance: ExcelInstance Value: DataTable.ColumnHeadersRow CellName: $'''A1''' Excel.WriteToExcel.WriteCell Instance: ExcelInstance Value: DataTable Column: $'''A''' Row: 2

How to copy/paste the above code into your PAD ?
