title: Excel unable to get css styles from xlsxwriter python
body: <p>I am creating a report in xlsxwriter with some styles like merged cells, font styles, colors, etc...</p>
  
  <p>All code seems right, I'm following the docs and tips and the file is being saved correctly but when I try to open the file on Microsoft Excel it says that the file has some corrupted styles.</p>
  
  <p>When I open the file on Libre Office, Numbers and Wps, everything works well..</p>
