ADODB Stream convert binary to string - excel

Question

I'm facing a problem when trying to open a file from a URL using ADODB, and then using that as a string stream. Basically, the issue I'm facing is almost a duplicate of this question here:
convert ADODB binary stream to string vba
Except that I have to use an ADODB Stream to work with the content later on. Therefore, skipping ADODB completely is not an option, like in the answer in the other topic.
Right now, what I'm doing is making a HTTP GET Request, using a binary stream to save it as a file, then loading that very same file using a text stream. This works just fine, but there has to be a way to skip the saving-loading part and make it work directly.
Here is the code I have so far:
Dim myURL As String
myURL = "https://xyz.xyz/xyz.csv"
Dim WinHttpReq As Object
Set WinHttpReq = CreateObject("Microsoft.XMLHTTP")
WinHttpReq.Open "GET", myURL, False
WinHttpReq.Send
Dim objStream, strData
Dim leftcellstarttemp As Variant, rightcellstarttemp As Variant, leftcellendtemp As Variant, rightcellendtemp As Variant, r As Long, line As String, dtStr As String, mlValue As String, dtArr() As String
myURL = WinHttpReq.ResponseBody
If WinHttpReq.Status = 200 Then
Set oStream = CreateObject("ADODB.Stream")
oStream.Open
oStream.Type = 1
oStream.Write WinHttpReq.ResponseBody
oStream.SaveToFile "C:\Temp\file1.csv", 2
oStream.Close
Set objStream = CreateObject("ADODB.Stream")
objStream.Charset = "utf-8"
objStream.Type = 2
objStream.Open
objStream.LoadFromFile "C:\Temp\file1.csv"
line = objStream.ReadText(-2)
End If
Do Until objStream.EOS
(and so on, and so forth...)
Can you help me on how I can get past this needless file saving-loading process?
Thanks!
