converting a json file to csv

I am trying to convert a Postman output file from JSON to a CSV. In the past I have just used a json to csv converter but I have some sensitive data for a particular file and do not feel comfortable using an online tool. Searched for some code that might be able to help me with this. When I run this in visual studio I do not see a file created. I will admit I have not done any C# in years and all I really am using it for is to convert this one json file to a csv. Can someone please take a quick look at this code and let me know what I am doing wrong? The jsonInput is not the actual input I am using. Just want to use that as an example. I plan to use a filename for the input but can try figuring that out on my own. Just hoping to get some help to just get a file created.
```
using Aspose.Cells;
using Aspose.Cells.Utility;
using DocumentFormat.OpenXml.Spreadsheet;
using Microsoft.AspNet.SignalR.Json;
// load JSON data
string jsonInput = "[{'nodeId':1,'reputation':1134},{'nodeId':2,'reputation':547},{'nodeId':3,'reputation':1703},{'nodeId':4,'reputation':-199},{'nodeId':5,'reputation':-306},{'nodeId':6,'reputation':-49},{'nodeId':7,'reputation':1527},{'nodeId':8,'reputation':1223}]";
// create a blank Workbook object
var workbook = new Aspose.Cells.Workbook();
// access default empty worksheet
var worksheet = workbook.Worksheets[0];
// set JsonLayoutOptions for formatting
var layoutOptions = new JsonLayoutOptions();
layoutOptions.ArrayAsTable = true;
// import JSON data to CSV
Aspose.Cells.Utility.JsonUtility.ImportData(jsonInput, worksheet.Cells, 0, 0, layoutOptions);
// save CSV file
workbook.Save("Test.csv", SaveFormat.Csv);
```

XML Edit to file using C#

I am working on a WPF application and I have a simple XML file that I am parsing using 'XmlDocument' and is working fine for the readinh part.
I want the use to be able to add, edit or delete any node and save these changes to the file.
I tried using 'XElement' but it seems to change the instance itself and not the file.
My XML file looks something like this:
<Configuration>
<A_0.04_5>
<ML407Configuration>
<AM_Amp>10</AM_Amp>
<AMRJ_Amp>10</AMRJ_Amp>
<FM_Freq>20</FM_Freq>
<FM_Phase_Shift>20</FM_Phase_Shift>
</ML407Configuration>
<BertConfiguration>
<BERT_LR>25.78125</BERT_LR>
<BERT_PRBS>7</BERT_PRBS>
<BERT_Scaling>1000</BERT_Scaling>
</BertConfiguration>
</A_0.04_5>
<B_1.333_0.15>
<ML407Configuration>
<AM_Amp>10</AM_Amp>
<AMRJ_Amp>10</AMRJ_Amp>
<FM_Freq>20</FM_Freq>
<FM_Phase_Shift>20</FM_Phase_Shift>
</ML407Configuration>
<BertConfiguration>
<BERT_LR>25.78125</BERT_LR>
<BERT_PRBS>7</BERT_PRBS>
</BertConfiguration>
</B_1.333_0.15>
<C_4_0.05>
<ML407Configuration>
<BUJ_LR>25</BUJ_LR>
<BUJ_Pattern>7</BUJ_Pattern>
<PM_BUJ_Amp>7</PM_BUJ_Amp>
<BUJ_Amp>80</BUJ_Amp>
</ML407Configuration>
<BertConfiguration>
<BERT_LR>25.78125</BERT_LR>
<BERT_PRBS>7</BERT_PRBS>
</BertConfiguration>
</C_4_0.05>
</Configuration>
What I tried is the following:
string filePath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)+"/Configuration.xml";
XElement xml = XElement.Load(filePath);
// This seems to remove the node from xml instance and not from the file
// Should I save the file again or is there another way to do it
// Same applies for add and edit
xml.Elements("C_4_0.05").Remove();
I have seen a lot of similar questions but I don't know if any of them change directly to the file or not

XElement.Load loads an XML structure from a file into memory. Any changes you make to that structure are also done in memory. If you want to write those changes back to a file (technically called serialization) you need to call XElement.Save.

passing xml document to c# from php

I need to pass the following xml document to my c# dll from PHP .Also i only need to pass the element watchlists and its child element.Its a DOMDocument
<assumption_list>
<assumption name="test" id="23" description="test1" is_shared="no">
<watchlists>
<watchlist globalissuer="k" prepayrate="" prepaytype="CPR" defaultrate="" defaulttype="CDR" lossrate="" lagmonths=""/>
</watchlists>
</assumption>
</assumption_list>
1:Should i convert this xml document to string and then pass it to c# dll,if yes should is there any PHP function that does that like xmldoc.tostring() of c#
2:How do i grab the watchlists element from this xml document.i tried using this code.
$watchlists = $xmlDoc->getElementsByTagName('watchlists');
If this is the right way then how do i pass this node to c# ,should i convert it to string or just pass this xml node directly.
Any feedback would be really helpfull.

I dont think there is a SimpleXML::getElementsByTagName()
This should echo what you want:
$result = $xml->xpath('/assumption_list/assumption/watchlists');
foreach($result as $node)
echo $node->asXML();
DEMO
EDIT :
You edited your question and changed SimpleXML into DOMDocument
$result = $dom->getElementsByTagName('watchlists');
foreach($result as $element)
echo $dom->saveXML($element);

ReadXml from a Resource - Explanation

I've been working on a project (C#) and part of it was filling a data grid with an embedded xml file.
Although I've now found a way to make this work, i am still confused as to to theory behind it. And I'd like to stop and make sure i fully understand it before i continue with this project.
The code that i have working currently is;
XmlDataDocument myXML = new XmlDataDocument();
StringReader mytempXML = (new StringReader(BasicTest.Properties.Resources.myxml));
myXML.DataSet.ReadXml(mytempXML);
What is confusing to me is that before this solution, I was trying the below;
myXML.DataSet.ReadXml(BasicTest.Properties.Resources.myxml);
and it wasn't working. However using the full file path (like below) was working.
myXML.DataSet.ReadXml("C:/..etc../myxml.xml");
The Question I have is: why is a StringReader required for the ReadXml method if you're reading from a resource, but using a full file path works without?
If anyone could provide an explanation, that would be great.
Thanks.

This is because the ReadXml method takes a string. That string must be the name of a file. It cannot be XML. If you pass it a string that is XML, it will think that is the name of the file! It doesn't have the smarts to look at the string and ask "Is this string XML, or is it a file name?" and figure that out.
// Summary:
// Reads XML schema and data into the System.Data.DataSet using the specified
// file.
//
// Parameters:
// fileName:
// The filename (including the path) from which to read.
public XmlReadMode ReadXml(string fileName);
By wrapping the XML in a stringreader or a stream or something, you are calling a different overload, that expects XML instead of a file name.

XML header missing after converting an XML file into a Binary Format File

I have a problem. I have an XML spreadsheet file that I'm trying to send via email. So I converted into a binary file and attached it to an email. The problem is when I'm trying to open it (on Excel), it's not showing the data that I saved. When I opened it like an XML file I realized that it didn't saved the XML header:
The way it should be:
<?xml version="1.0" encoding="utf-8"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40">
...
<Styles>
...
</Styles>
<Worksheet>
...
</Worksheet></Workbook>
after converting:
<Worksheet>
...
</Worksheet>
I've tried to use an xmldocument but i wasn't working, I also tried using a string, still not working. This is how I convert the XML to binary:
UTF8Encoding encoding = new UTF8Encoding();
binaryFile = encoding.GetBytes(xmlFile);
How can I fix this problem?
Thanks.

I think we need more information on how you're converting the XML file.
From your description it sounds like you've saved an Excel Spreadsheet to XML and for whatever reason you cannot just attach this text document to an email. My guess is you're using a method to attach the XML file that requires a byte array and can't just be provided a file location. If you could provide more information on this, it would help us figure out where things are going wrong for you.
The part I'm really stuck on is:
I've tried to use an xmldocument but i wasn't working, I also tried
using a string, still not working.
How did you try string? Did you read the file from disk using FileStream? If so, you should have been able to retrieve the full contents of the file.
Were you using XmlDocument the whole time and trying XmlDocument.OuterXml? This probably won't give you the control headers since they're not part of the XML body inside the root node.
So really there are two things I would have tried. First, if I had an XML file on disk and needed to attach it to an email through code and my only option was to provide a byte array, I'd do something like:
using (FileStream fs = new FileStream("", FileMode.Open, FileAccess.Read))
{
byte[] binaryFile = new byte[fs.Length];
fs.Read(binaryFile, 0, buff.LongLength);
//Copy the byte array to your email object.
}
Now if this isn't what you're doing, you'll need to provide a lot more detail on what you are starting with (file on disk?), what you need to do (send automated email?), what constraints you have and any other information that would limit potential solutions.

I've found my mistake: I didn't serialized the XML file so that's why after the conversion it just shows the data without the XML header. so there's 2 ways to resolve this problem:
first, we can concatenate the header with the data string, or we can use the serialize function. This is where I've found how to do it.
