Styling excel from XSL: table error

Question

So I wanted to add some styles in my excel XSLT. The logics are working fine but when I am trying to add style its giving error like

Excel error: Problem came up in the following areas during load: Table

Errors listed in: c:\Users\uname\appdat\microsoft\windows\temporaryInternetFiles\content.MSO\xxxxxxxx.log

My code is:

<?xml version="1.0" encoding="UTF-8"?>
<?mso-application progid="Excel.Sheet"?>

                                </ss:Data>
                                </ss:Cell>

                </ss:Worksheet>
            </ss:Workbook>
    </xsl:template>

    <xsl:template match="m:*">
        <xsl:variable name="data" select="."/>
        <ss:Row>
            <xsl:for-each select="$fields"> 
                <ss:Cell>
                    <ss:Data ss:Type="String">
                        <xsl:value-of select="$data/*[name()=current()]/text()"/>
                    </ss:Data>
                </ss:Cell>
             </xsl:for-each>
        </ss:Row>
    </xsl:template>
</xsl:stylesheet>

I actually wanted to bold the fonts of header, keep the border and give background color to header.

Answer 1

There's 2 errors in your XSLT:

1. Your <Styles>are outside of any template, they will not appear in your output document at all. They need to be inside Workbook.

2. Cell does not have an ss:ID attribute only Style has ss:ID, to reference the Style use ss:StyleID="s62" instead.

Take a look inside c:\Users\uname\appdat\microsoft\windows\temporaryInternetFiles\content.MSO\xxxxxxxx.log (you cannot browse to that location, the folder is hidden, so copy that path into your explorer Adressbar or in a "Run" window) it would have given you some more information like:

XML ERROR in Table
REASON: Illegal Tag
FILE:   C:\temp\Untitled15.xls
GROUP:  Row
TAG:    Cell
ATTRIB: ID
VALUE:  s62

Office throws notoriously bad error messages but that and looking in you result document should usually give you some clue.
