Parse JSON, MS Access VBA (nested loops) - json

Question

good people of StackOverflow!
I am trying to figure out how to connect to Airtable API, get JSON from there and populate Access table with the results.
So far, at least I managed to restrict the request to give me only a few fields I need.The result looks like this:
{
"records": [{
"id": "rec008lgyvVmwk1F4",
"fields": {
"Date": "2018-02-28"
},
"createdTime": "2018-01-26T15:36:23.000Z"
}, {
"id": "rec02WozJeaGvfBfj",
"fields": {
"Hours": 1.5,
"Date": "2018-02-09",
"Project": ["Nonbillable"]
},
"createdTime": "2018-02-12T17:03:18.000Z"
}, {
"id": "rec05VxP0CYTsDYOA",
"fields": {
"Date": "2018-02-08"
},
"createdTime": "2018-02-01T10:29:52.000Z"
}, {
"id": "rec05xoQEm5iWIYmz",
"fields": {
"Hours": 0.75,
"Date": "2018-02-16",
"Project": ["2018 - Japan DLAs"]
},
"createdTime": "2018-02-19T09:29:18.000Z"
}]
}
From that point on I have read as many examples as I could find how to use VBA-JSON by Tim Hall (thank you Tim, for creating it :)
As far as I understand, in my case the ParseJson function returns a dictionary. Inside that is a collection named 'results' and inside that collection is another dictionary named 'fields'.
What I need are values for keys 'Hours', 'Date' and 'Project' from that dictionary.
I have tried to do those three loops (loop through dictionary inside collection inside dictionary) and was failing miserably many times with a variety of errors. Finally, I have come to the point where I see no more errors, the sub happily gives me "Import done!" message. Alas, my table is empty!
What, what am I doing wrong?
I hope I gave you enough information and thank you very much in advance for your help!
(If it matters, I'm working with 32-bit Access 2016 on 64-bit Windows)

Answer 1

The entry Project holds an Array so take the first Item:
Set Parsed = JsonConverter.ParseJson(JsonRetrieved)
For Each record In Parsed("records")
Set fields = record("fields")
If fields.Exists("Hours") Then
rs.AddNew
rs!AirtableHours = fields("Hours")
rs!AirtableDate = fields("Date")
rs!AirtableProject = fields("Project")(1)
rs.Update
End If
Next
