I just saw this now - is there a feature for StackOverflow to alert me when a comment is added or a question answered, so I know to look back?
Here is starting code:

EDIT 23-APRIL add more code.
the Me. comes from code in a Userform.
Set jLib = New JSONLib
vRequestBody = "{"
If Me.txtDaysCreated > "" Then
vRequestBody = vRequestBody & JKeyValue("start_date", Format$(Now() - CDbl(Me.txtDaysCreated), "yyyy-mm-dd")) & ","
End If
If Me.txtTitleContains > "" Then
' title contains "text", case insensitive
vRequestBody = vRequestBody & JKeyValue("title", Me.txtTitleContains) & ","
End If
vRequestBody = vRequestBody _
& JKeyValue("fields", Array("title", "date_created", "date_modified", "num_responses", _
"language_id", "question_count", "preview_url", "analysis_url")) & "}"
'returns in this order: 0=date_modified 1=title 2=num_responses 3=date_created 4=survey_id
' and in date_created descending
sResponse = GetSMAPIResponse("get_survey_list", vRequestBody)
------------------------------------------
Function JKeyValue(sKey As String, vValues As Variant) As String
Dim jLib As New JSONLib
JKeyValue = jLib.toString(sKey) & ":" & jLib.toString(vValues)
Set jLib = Nothing
End Function
Edit 25-April overview of VBA code to get the data
This is covered in the SM documentation, but I'll sketch how that looks in VBA.
the response to get_survey_details gives you all the survey setup data. Use
Set oJson = jLib.parse(Replace(sResponse, "\r\n", " "))
to get a json object.
Set dictSurvey = oJson("data")
gives you the dictionary so you can get data like dictSurvey("num_responses"). I take it you know how to index into dictionary objects to get field values.
Set collPages = dictSurvey("pages")
gives you a collection of Pages. The undocumented field "position" gives you the order of pages in the survey UI.
For lPage = 1 To collPages.Count
Set dictPage = collPages(lPage)
Set collPageQuestions = dictPage("questions") ' gets you the Qs on this page
For lPageQuestion = 1 To collPageQuestions.Count
Set dictQuestion = collPageQuestions(lPageQuestion) ' gets you one Q
Set collAnswers = dictQuestion("answers") ' gets the QuestionOptions for this Q
For lAnswer = 1 To collAnswers.Count
Set dictAnswer = collAnswers(lAnswer) ' gets you one Question Option
etc etc
Then given the number of responses from above, loop through the respondents 100 at a time - again see the SM doc for details of how to specify start and end dates to do incremental downloads over time.
create a json object from the response to "get_respondent_list"
Collect the fields for each respondent and accumulate a list of at most 100 respondent IDs.
Then "get_responses" for that list.
Set collResponsesData = oJson("data")
For lResponse = 1 To collResponsesData.Count
If not IsNull(collResponsesData(lResponse)) then
... get fields...
Set collQuestionsAnswered = collResponsesData(lResponse)("questions")
For lQuestion = 1 To collQuestionsAnswered.Count
Set dictQuestion = collQuestionsAnswered(lQuestion)
nQuestion_ID = CDbl(dictQuestion("question_id"))
Set collAnswers = dictQuestion("answers") ' this is a collection of dictionaries
For lAnswer = 1 To collAnswers.Count
On Error Resume Next ' only some of these may be present
nRow = 0: nRow = CDbl(collAnswers(lAnswer)("row"))
nCol = 0: nCol = CDbl(collAnswers(lAnswer)("col"))
nCol_choice = 0: nCol_choice = CDbl(collAnswers(lAnswer)("col_choice"))
sText = "": sText = collAnswers(lAnswer)("text")
nValue = 0: nValue = Val(sText)
On Error GoTo 0
and save all those values in a recordset or sheet or whatever
Hope that helps.
