title: How to insert and format values cell by cell in an XLSX file using openpyxl
body: <p>I am trying to write an XLSX file using the openpyxl module. I am using the <code>append()</code> method to insert the values row by row. But I want to insert the values cell by cell instead. I would also like to format the cell (font, colour, alignment etc). Please help me.</p>
