OpenAI API VBA function returns #Value! but MsgBox displays response
题意：“OpenAI API VBA 函数返回 #Value!，但 MsgBox 显示响应”题目背景：
I am trying to integrate the OpenAI API into Excel. The http request to OpenAI chat completion works correctly and the response is OK. When I display it with a MsgBox, it looks fine.
“我正在实验将 OpenAI API 集成到 Excel 中。对 OpenAI 谈天完成的 HTTP 哀求正常工作，响应也正常。当我使用 MsgBox 显示它时，它看起来很好。”
But when the function is called in a sheet, the returned value is #VALUE!
“但当在工作表中调用该函数时，返回的值是 #VALUE!”
Public Function GPT(InputPrompt) As String
'Define variables
Dim request As Object
Dim text, response, API, api_key, DisplayText, GPTModel As String
Dim GPTTemp As Double
Dim startPos As Long
Dim rng As Range
Dim httpRequest As Object
Dim countArray As Variant
'API Info
API = "https://api.openai.com/v1/chat/completions"
api_key = Trim(Range("API_Key").value)
'Note: for future upgrades, please replace with GPT-4 etc
GPTModel = Range("Model_Number").value
If api_key = "" Then 'API key is missing!
MsgBox "Error: API cannot be blank! Please go to 'Configuration' tab and enter a valid OpenAI API key", vbExclamation, "GPT for Excel"
frmStatus.Hide
Exit Function
End If
'Clean input text and make JSON safe
text = CleanInput(InputPrompt)
'Create request object
Set httpRequest = CreateObject("MSXML2.XMLHTTP")
'Set httpRequest = New MSXML2.XMLHTTP60
'Get temp from Config panel
GPTTemp = Range("GPT_temperature").value
'Assemble request body
Dim requestBody As String
requestBody = "{""model"": ""gpt-4"", ""messages"": [{""role"": ""user"", ""content"": """ & text & """}], ""temperature"": 0.7}"
With httpRequest
.Open "POST", API, False
.setRequestHeader "Content-Type", "application/json"
.setRequestHeader "Authorization", "Bearer " & api_key
.send (requestBody)
End With
If httpRequest.Status = 200 Then 'Successfully called OpenAI API
response = httpRequest.responseText
'Get usage info from response object
countArr = ExtractUsageInfo(response)
startPos = InStr(response, """content"":") + Len("""content"":") + 2
endPos = InStr(startPos, response, "},")
DisplayText = Trim(Mid(response, startPos, endPos - startPos))
DisplayText = Mid(DisplayText, 1, Len(DisplayText) - 2)
DisplayText = CleanOutput(DisplayText)
Set request = Nothing
If FillActive = False Then frmStatus.Hide
MsgBox (GPT)
GPT = DisplayText
MsgBox (GPT)
If Range("Log_Data").value = "Yes" Then
Call UpdateLogFile(countArr)
End If
Exit Function
End Function
题目解决：
You are limited as to what you can do in a custom worksheet function. While I can't find an explicit reference to making web or API calls in the MS Docs my experience of worksheet functions leads me to not be surprised that this doesn't work.
“在自界说工作表函数中，你的操作是有限的。虽然我在微软文档中找不到明确提到进行 Web 或 API 调用的内容，但根据我对工作表函数的履历，这种方法不起作用并不令人不测。”
An alternative would be to add a Button or Shape to your worksheet then associated that button with a Sub such as
“另一种方法是在你的工作表中添加一个按钮或形状，然后将该按钮与一个 `Sub` 关联，例如：”
Sub ButtonClicked()
Dim Response As String, InputPrompt As String
InputPrompt = CStr(ThisWorkbook.Sheets("Sheet1").Range("A1").Value)
Response = GPT(InputPrompt)
ThisWorkbook.Sheets("Sheet1").Range("A2").Value = Response
End Sub Which uses your existing GPT function to get a response for the text in cell A1 and loads it into cell A2 (both in 'Sheet1' in this case ... obviously you can change the cells and worksheet as needed).
“这个方法使用你现有的 `GPT` 函数来获取单元格 A1 中的文本的响应，并将其加载到单元格 A2 中（在本例中，这两个单元格都在 'Sheet1' 中……显然，你可以根据须要更改单元格和工作表）。”
