Import Data in Excel from a table created by a scr

问题:

I am trying to create a macro that automatically connect to a web page and import in excel the data from a table. My problem is that Excel Query tool does not recognize the table, I think because it's create by a script in the page, and so I cannot use the standard way. For now, I am using this method:

1. Copy the data into the clipboard
2. Run a vba macro than gets the data from the clipboard and imports it in Excel

However, I have more than 20 web pages to import every time and I would like a "standalone" macro which, given the url of the page, can import the data in excel.

The webpage I am interested in is: http://www.investing.com/indices/us-30-historical-data I am using excel 2010

Can anyone help me?

Try this

Sub Dow_HistoricalData()

    Dim xmlHttp As Object
    Dim TR_col As Object, TR As Object
    Dim TD_col As Object, TD As Object
    Dim row As Long, col As Long

    Set xmlHttp = CreateObject("MSXML2.XMLHTTP.6.0")
    xmlHttp.Open "GET", "http://www.investing.com/indices/us-30-historical-data", False
    xmlHttp.setRequestHeader "Content-Type", "text/xml"
    xmlHttp.send

    Dim html As Object
    Set html = CreateObject("htmlfile")
    html.body.innerHTML = xmlHttp.ResponseText

    Dim tbl As Object
    Set tbl = html.getElementById("curr_table")

    row = 1
    col = 1

    Set TR_col = html.getelementsbytagname("TR")
    For Each TR In TR_col
        Set TD_col = TR.getelementsbytagname("TD")
        For Each TD In TD_col
            Cells(row, col) = TD.innerText
            col = col + 1
        Next
        col = 1
        row = row + 1
    Next
End Sub

Another approach would be to make an HTTP request like

// source http://tkang.blogspot.co.at/2010/09/sending-http-post-request-with-vba.html
Dim result As String
Dim myURL As String
Dim winHttpReq As Object
Set winHttpReq = CreateObject("WinHttp.WinHttpRequest.5.1")

myURL = "http://192.168.10.101:80/your_web_service?parameter=hello¶meter2=hi"

winHttpReq.Open "GET", myURL, False
winHttpReq.Send

result = winHttpReq.responseText

and parse the result. I haven't tried it myself though.
