In the actual develpment, we offen encounter such a problem about exporting data to excel or word, especially excel.

I can export data to excel from gridview, but i can not apply styles to the excel cell. Last week, i found how to set the style.

For example:

the following is from:http://en.wikipedia.org/wiki/Microsoft_Office_XML_formats

<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook
   xmlns="urn:schemas-microsoft-com:office:spreadsheet"

  </ExcelWorkbook>
  <Styles>
    <Style ss:ID="Default" ss:Name="Normal">
      <Alignment ss:Vertical="Bottom" />
      <Borders />
      <Font />
      <Interior />

    <Style ss:ID="s21">

  </Styles>

    <Table ss:ExpandedColumnCount="2" ss:ExpandedRowCount="5"
    x:FullColumns="1" x:FullRows="1">
      <Row>
        <Cell>
          <Data ss:Type="String">Text in cell A1</Data>
        </Cell>
      </Row>
      <Row>
        <Cell ss:StyleID="s21">
          <Data ss:Type="String">Bold text in A2</Data>

        </Cell>

      <Row>
        <Cell ss:Index="2" ss:Formula="=R[-1]C/2">
          <Data ss:Type="Number">21.5</Data>
        </Cell>
      </Row>
    </Table>
    <WorksheetOptions xmlns="urn:schemas-microsoft-com:office:excel">
      <Print>
        <ValidPrinterInfo />
        <HorizontalResolution>600</HorizontalResolution>
        <VerticalResolution>600</VerticalResolution>
      </Print>
      <Selected />
      <Panes>
        <Pane>
          <Number>3</Number>
          <ActiveRow>5</ActiveRow>

      </Panes>

    </WorksheetOptions>
  </Worksheet>
</Workbook>

And i found a open source project http://excelpackage.codeplex.com/ which can easily create ooxml.

The same as excel, we can export data to word:

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<?mso-application progid="Word.Document"?>
<w:wordDocument
   xmlns:w="http://schemas.microsoft.com/office/word/2003/wordml"

   w:macrosPresent="no"
   w:embeddedObjPresent="no"
   w:ocxPresent="no"
   xml:space="preserve">

If we want to export some complex data to excel, we can create the xml manually, apply every style we like we want
