After export, open the sheet (manually or, if you're up to it, via automation) and apply formatting. If automation, you'd have to loop through the rows, check the value in the remarks cell, and if it contains that value, apply the formatting to the whole row. Now I haven't done lot of excel automation last seven years, so the syntax is probably wrong:

oSheet=oExcel.activeSheet
for each oRow in oSheet.rows
    if oRow.cells(32).value="your value"
       oRow.color=0xff0000   && or whatever goes for red in excel
    endif
endfor

Not sure if this is the proper way to get a reference to the active sheet, maybe you need to get active workbook first, then the sheet from it. I took 32 as an example; your remarks cell may be in any column - you'll know which.
