Excel XML: Formatting inline text

Question

I am trying to apply inline styling to a cell within an Excel spreadsheet with the aim of having bold, non-bold and different coloured text within a single cell.

I am using the following:

<Row>
  <Cell ss:StyleID="s1">
    <ss:Data ss:Type="String" xml:space="preserve" xlmns="http://www.w3.org/TR/REC-html40"><Font>Black text</Font><B>Bold text</B><Font html:Color="#FF0000">Red text</Font></ss:Data>
  </Cell>
</Row>

Unfortunately, this does not seem to have any effect. When I open in Excel, my text appears all black and non-bold.

I am completely stumped as I believe <Font html:Color="#FF0000">Red text</Font> and <B>Bold text</B> to be the correct elements to use.

Here is my full XML:

Is seems it is possible. You just made a typo. :)

Change xlmns to xmlns
