Converting XML Spreadsheet to PDF

Postby doknek » Thu Jul 14, 2011 7:29 pm

Is it possible to convert "XML Spreadsheet" (.xml) format to PDF? If yes, please provide code samples.

I tried following code to convert:
Code: Select all
        Dim workbook As New Workbook()
        workbook.LoadFromFile(file)


But getting the exception:
Code: Select all
[ArgumentNullException: Value cannot be null.
Parameter name: root]
   Spire.CompoundFile.XLS.Native.Storage..ctor(IStorage root, String storageName) +171
   Spire.CompoundFile.XLS.Native.Storage..ctor(IStorage root) +35

Dear doknek,
Thanks for your inquiry.

It's OK to do so. But you need to use Spire.Xls.
Firstly, you can convert xml to Excel.
Sencondly, you can convert Excel to pdf.
Here is a sample code.
Code: Select all
            Workbook workbook = new Workbook();
            workbook.LoadFromXml("Xml Spreadsheet.xml");
            PdfConverter pdfConverter = new PdfConverter(workbook);

            PdfDocument pdfDocument = new PdfDocument();
            pdfDocument.PageSettings.Orientation = pdf.PdfPageOrientation.Landscape;
            pdfDocument.PageSettings.Width = 970;
            pdfDocument.PageSettings.Height = 850;

            PdfConverterSettings settings = new PdfConverterSettings();
            settings.TemplateDocument = pdfDocument;
            pdfDocument = pdfConverter.Convert(settings);

            pdfDocument.SaveToFile("test.pdf");
        }

This works great.

1. Can we force all the columns from the spreadsheet to fit on the pdf page? Half of the columns are appearing on the next page.

2. XML worksheet has settings for WindowHeight, WindowWidth, WindowTopX, WindowTopY. Can we use these settings for PDF to make the spreadsheet fit correctly?

Dear doknek,
Thanks for your inquiry.

You can set wider pdfWidth to do so.
Code: Select all
//set wider width
pdfDocument.PageSettings.Width = 1500;

Dear doknek,

It's ok to set the width automatically.
Here is a sample code
Code: Select all
pdfDocument.PageSettings.Width = (float)getWidth(sheet);
private static double getWidth(Worksheet worksheet)
        {
            double width = 0;
            foreach (var cell in worksheet.Columns)
            {
                width += cell.ColumnWidth;
            }
            return width * 8.5;
        }
