I have written an Excel VBA macro which imports data from a HTML file (stored locally) before performing calculations on the data.
At the moment the HTML file is ref
I think the problem is that opening the file without a path will only work if your "current directory" is set correctly.
Try typing "Debug.Print CurDir" in the Immediate Window - that should show the location for your default files as set in Tools...Options.
I'm not sure I'm completely happy with it, perhaps because it's somewhat of a legacy VB command, but you could do this:
ChDir ThisWorkbook.Path
I think I'd prefer to use ThisWorkbook.Path to construct a path to the HTML file. I'm a big fan of the FileSystemObject in the Scripting Runtime (which always seems to be installed), so I'd be happier to do something like this (after setting a reference to Microsoft Scripting Runtime):
Const HTML_FILE_NAME As String = "my_input.html"
With New FileSystemObject
With .OpenTextFile(.BuildPath(ThisWorkbook.Path, HTML_FILE_NAME), ForReading)
' Now we have a TextStream object that we can use to read the file
End With
End With
