When opening and saving a file that contains named ranges (most at the worksheet level) the resulting SpreadsheetML has errors in the named ranges.
Here is the sample code and the file is attached:
[Test]
public void Save_WorksheetNamedRanges_OpensInExcel()
{
var workbook = new Workbook();
workbook.Open("WorksheetNamedRanges.xls", FileFormatType.Default);
workbook.Save("WorksheetNamedRanges.xml", FileFormatType.SpreadsheetML);
}
