As an alternative, can anyone confirm if formulae are kept in xml
formatted spreadsheets, for example of gnumeric or LO calc xml
spreadsheets are imported by m$? For example simple formula from
gnumeric:
...
      <gnm:Cells>
        <gnm:Cell Row="0" Col="0" ValueType="40">3</gnm:Cell>
        <gnm:Cell Row="1" Col="0" ValueType="40">5</gnm:Cell>
        <gnm:Cell Row="2" Col="0" ValueType="40">3</gnm:Cell>
        <gnm:Cell Row="3" Col="0">=(A1*A2)/A3</gnm:Cell>
      </gnm:Cells>
...

from LO calc, saved as fods:
...
<table:table-row table:style-name="ro1">
               <table:table-cell
table:formula="of:=([.A1]*[.A2])/[.A3]" office:value-type="float"
                                 office:value="5">
                  <text:p>5</text:p>
               </table:table-cell>
            </table:table-row>
...

from LO calc, saved as m$ 2003 xml:
...
<Table ss:StyleID="ta1">
                        <Column ss:Width="64.2614"/>
                        <Row ss:Height="12.8126">

                                        <Data ss:Type="Number">3</Data>
                                </Cell>
                        </Row>
                        <Row ss:Height="12.8126">
                                <Cell>
                                        <Data ss:Type="Number">5</Data>
                                </Cell>
                        </Row>
                        <Row ss:Height="12.8126">
                                <Cell>
                                        <Data ss:Type="Number">3</Data>
                                </Cell>
                        </Row>
                        <Row ss:Height="12.8126">

                                </Cell>
                        </Row>
                </Table>
