title: How to get from numeric cell address to Excell format python in xlsxWriter
body: <p>import xlsxwriter</p>
  
  <p>I have cell like </p>
  
  <p>Ex1:
  form1 = worksheet.write(0, 0, 'Foo', format)</p>
  
  <p>The actual address like this 'A1'.</p>
  
  <p>Like 
  Ex2: 
  form2 = worksheet.write(8, 27 'Foo', format)</p>
  
  <p>The cell address is AB8</p>
  
  <p>How to get the values like 'A1' and 'AB8' from numeric. 
  Is there any function in xlsxwriter or any logic have to written.</p>
  
  <p>Because if we are giving </p>
  
  <p>worksheet.<strong>write_formula</strong>(row_Number, Col_Num+1,'{=SUM(row_number,Col_Num-len(issueList)+1,row_Number,Col_Num)}')/</p>
  
  <p>Instead doing the summation <strong>'{=SUM(row_number,Col_Num-len(issueList)+1,row_Number,Col_Num)}'</strong>.only text it is printing.</p>
  
  <p>Thanks in advance.</p>
