The title of every worksheet must be positioned in cell A1 and this includes the title of the spreadsheet itself. Style the title in heading 1, with heading 2 for any subsidiary title, then normal font for the rest of the text.
At the moment we're suggesting heading 1 is 16pt Arial bold, and heading 2 Arial 14 pt, normal text Arial 12 point.
To create the right style, click on the heading text, click Cell styles, scroll down to Heading 1, right click on it and select Modify then Format. On the Font tab, select the options listed above (Arial, correct font size, bold or regular). Make sure the colour is set to 'Automatic'. On the Border tab click None, then OK. You should have permanently modified the header style whenever it is applied throughout the workbookFont Arial 12 point.
Avoid colour or any other kind of fancy or decorative formatting.
