Excel How To

How Can i convert a excel spreadsheet to a XML File
Posted: 23 Mar 06

The following code belows creates a structured XML file from a excel spreadsheet. In this instance the spreadsheet is called CGT and has data starting in Cell B3 with headings starting in cell B2.

The code has some generic features in it , such as finding used columns and rows.

Another feature is, it uses the data in column B to create a XML Heading when the data changes in column B. It also uses the spreadsheet name as the main XML tag.

Below is a cut down version of the data being used

CODE

CGTHEADING,CGTDATE,CGTDESC,CGTCODE,CGTNOMINEE,CGTTYPE,CGTEVENT,CGTEVENTDESC,CGTQUANTITY,CGTAMOUNT
Acquisitions,10/02/2005,Some Made Up Company ,NTFEEE,ANWM,BULK,BS,Purchase,1176.471113,"ú1,950.00"
Acquisitions,10/02/2005,Another Made Up Co,OPEG,ANWM,BULK,BS,Purchase,783.568888,"ú3,900.00"
Disposals,06/01/2005,Acme Made Up Company ,3244225,ANWM,INDIVIDUAL,LA,Lapse,-4258.84,ú0.00

And here is how the XML file looks

CODE


  <?xml version="1.0" ?>
- <CGT>
- <RECORD>
  <CGTHEADING>Acquisitions</CGTHEADING>
- <DATA>
  <CGTDATE>10/02/2005</CGTDATE>

  <CGTQUANTITY>1176.471113</CGTQUANTITY>

  <CGTHEADING>Disposals</CGTHEADING>

  <CGTNOMINEE>ANWM</CGTNOMINEE>
  <CGTTYPE>INDIVIDUAL</CGTTYPE>
  <CGTEVENT>LA</CGTEVENT>
  <CGTEVENTDESC>Lapse</CGTEVENTDESC>
  <CGTQUANTITY>-4258.84</CGTQUANTITY>
  <CGTAMOUNT>0</CGTAMOUNT>
  </DATA>
  </RECORD>
  </CGT>


The code which produces is the xml file from the spreadsheet is as follow s

CODE

Open "C:\temp\test2.xml" For Output As #iFileNum

'move through columms

    asCols(i) = oWorkSheet.Cells(2, i + 1).Value
Next i

If i = 0 Then GoTo ErrorHandler
    lCols = i

Print #iFileNum, "<?xml version=""1.0""?>"

For i = 3 To lRows

    If Trim(oWorkSheet.Cells(i, 2).Value) = "" Then
        Exit For
    End If
    
Debug.Print oWorkSheet.Cells(i, 2).Value
    If str_switch <> oWorkSheet.Cells(i, 2).Value Then
        If blnSwitch = True Then
            Print #iFileNum, "</" & "RECORD" & ">"
        End If

            blnSwitch = True
    Else
           
    End If
            Print #iFileNum, "<" & "DATA" & ">"
            For j = 3 To lCols
                Print #iFileNum, " <" & asCols(j - 1) & ">" & Trim(oWorkSheet.Cells(i, j).Value) & "</" & asCols(j - 1) & ">"
            Next j

     str_switch = oWorkSheet.Cells(i, 2).Value
Next i

'------------End & close File --------------------
