title: Want to make Excel file heading bold
body: <p>I want to make the Excel file heading as bold.
  In below code I clearly mentioned the headings that I want to make bold:</p>
  <pre><code>excel_document = openpyxl.load_workbook(r&quot;trial.xlsx&quot;, data_only=True)
  sheet = excel_document[&quot;Sheet1&quot;]
  wb = openpyxl.Workbook()
  sheets = wb.active
  #Following are the headings, i want to make bold
  sheets.cell(row=1, column=1).value=&quot;Device Type&quot;
  sheets.cell(row=1, column=2).value=&quot;Device ID&quot;
  sheets.cell(row=1, column=3).value=&quot;Status&quot;
  </code></pre>
