Re: [Dhis2-devs] Web API in Excel

 

Thanks Bob,

1. I have not established a preference here - your point on using CSV is a good one. CSV will probably be easier to "deserialize" in most cases. JSON or XML on the other hand, will probably be a little more robust to changes in the WebAPI output. 

2. I like it. Excel is a good tool accessible to many people. I have been using an excel sheet to manage some data through the API, but the sheet I made contains some "hardcodings" that is made for my specific case. I have been thinking about making a generic version of my Excel, that can be used by anyone to post, put and maybe also get data through the API.

Best regards
Markus

p.s. I deleted the stackexchange question again, as the question and answer was generic Excel, and not so DHIS related. The link still works, but here is the code snippet.

It is possible to use Excel Macros to call the Web API. Posting to the API can be done like this:

Public Function postData(ByVal address As String, ByVal json As String, ByVal mode As String)
    If (mode = "Yes" Or mode = "Debug") Then
        On Error GoTo Errorhandler
        Dim objHTTP As New WinHttpRequest
        URL = address
        objHTTP.Open "POST", URL, False
        objHTTP.Option(WinHttpRequestOption_SslErrorIgnoreFlags) = 13056

        objHTTP.setRequestHeader "Content-Type", "application/json"
        objHTTP.setRequestHeader "Authorization", "Basic " & EncodeBase64("admin:district")
        objHTTP.send json

        If (mode = "Debug") Then
            postData = objHTTP.ResponseText
            Else
            postData = objHTTP.statusText
        End If
    Else
        postData = mode
    End If

    Exit Function 
    Errorhandler:     
        postData = Err.Description 
End Function
For doing a GET, you should be able to just replace the "POST" with a "GET", and send the request without the json.
