Export Excel table range to XML using VBA
Today I needed to export a table in Excel into an XML format, and here's the code I whipped up to do it.
All you have to do is select the table range, then run the ExportRangeToXML procedure. You'll be prompted for a filename and location to save the XML file. You can customise the XML Element names used in the XML structure for the table and rows. The table headers are used for Element names in each row of data.

If strFilePath = vbNullString Then Exit Sub 'Get table data varTable = Selection.Value varColumnHeaders = Selection.Rows(1).Value 'Build xml strXML = "<?xml version=""1.0"" encoding=""utf-8""?>" strXML = strXML & "<" & strTableElementName & ">" For intRow = 2 To UBound(varTable, 1) strXML = strXML & "<" & strRowElementName & ">" For intCol = 1 To UBound(varTable, 2) strXML = strXML & "<" & varColumnHeaders(1, intCol) & ">" & _ varTable(intRow, intCol) & "</" & varColumnHeaders(1, intCol) & ">" Next strXML = strXML & "</" & strRowElementName & ">" Next strXML = strXML & "</" & strTableElementName & ">" 'Get next file number intFileNum = FreeFile 'Open the file, write output, then close file Open strFilePath For Output As #intFileNum Print #intFileNum, strXML Close #intFileNum End Sub |
Replace IF(ISERROR()) with value_if_false argument
This tip relates to the technique of trapping and handling errors in a formula. Prior to Excel 2007 (e.g. Excel 2003, 2002, 2000), this was accomplished using a combination of the IF and ISERROR functions to test for an error in a formula, e.g. =IF(ISERROR(MyFormula),ReturnSomethingElse,MyFormula).
A reader of my blog was after some code to do something a little different to a previous post which looked at replacing the Excel 2007 IFERROR function with IF and ISERROR.
The slight twist on this was when you wanted to get rid of the error trapping (IF and ISERROR) and just have the original formula, warts (errors) and all!
In the VBA code below, I have developed a handy procedure (ReplaceIFISERRORCellFormulas) that will convert a range of selected cells that contain IF(ISERROR()) formulas to instead display the formula used in the 'value_if_false' argument of the original IF(ISERROR()) function.
Use VBA to test the internet connection
In some of my applications I utilise the IE web browser control to display reports, some of which request internet content (e.g. Google Chart API and Google Maps API).
The trouble is, you can't always guarantee that the users PC has an internet connection. So, what's the best approach to the problem? Well, check the internet connection using the handy bit if VBA code below!
Private Declare Function InternetGetConnectedStateEx Lib "wininet.dll" (ByRef lpdwFlags As Long, ByVal lpszConnectionName As String, ByVal dwNameLen As Integer, ByVal dwReserved As Long) As Long 'Testing for internet connection Public Function IsInternetConnected() As Boolean IsInternetConnected = InternetGetConnectedStateEx(0, "", 254, 0) End Function |
