So, I\'ve got a bunch of content that was delivered to us in the form of Excel spreadsheets. I need to take that content and push it into another system. The other system ta

Answer 1

You might like to consider ADO - a worksheet or range can be used as a table.

Const adOpenStatic = 3
Const adLockOptimistic = 3
Const adPersistXML = 1

Set cn = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.Recordset")

''It wuld probably be better to use the proper name, but this is
''convenient for notes
strFile = Workbooks(1).FullName

''Note HDR=Yes, so you can use the names in the first row of the set
''to refer to columns, note also that you will need a different connection
''string for >=2007
strCon = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & strFile _
        & ";Extended Properties=""Excel 8.0;HDR=Yes;IMEX=1"";"


cn.Open strCon
rs.Open "Select * from [Sheet1$]", cn, adOpenStatic, adLockOptimistic

If Not rs.EOF Then
    rs.MoveFirst
    rs.Save "C:\Docs\Table1.xml", adPersistXML
End If

rs.Close
cn.Close

Here is the example macro to convert the Excel worksheet to XML file.

#'vba code to convert excel to xml

Sub vba_code_to_convert_excel_to_xml()
Set wb = Workbooks.Open("C:\temp\testwb.xlsx")
wb.SaveAs fileName:="C:\temp\testX.xml", FileFormat:= _
        xlXMLSpreadsheet, ReadOnlyRecommended:=False, CreateBackup:=False

End Sub

This macro will open an existing Excel workbook from the C drive and Convert the file into XML and Save the file with .xml extension in the specified Folder. We are using Workbook Open method to open a file. SaveAs method to Save the file into destination folder. This example will be help full, if you wan to convert all excel files in a directory into XML (xlXMLSpreadsheet format) file.
