title: Write a numpy.ndarray to an xlsx spreadsheet
body: <p>I am trying to use xlsxwriter to write a numpy.ndarray to an excel spreadsheet. </p>
  
  <p>The 'type' of my array is numpy.ndarray. The array itself when printed takes this form: </p>
  
  <pre><code>exampleArray = array([[[0.    ,  1], [0.    , 1], [0.    ,1]]])
  </code></pre>
  
  <p>The code that I am using is as follows: </p>
  
  <pre><code>workbook = xlsxwriter.Workbook('WorkBookName.xlsx')
  worksheet = workbook.add_worksheet('workSheetName')
  
  row = 0
  col = 0
  
  for data in exampleArray[0]:
      worksheet.write_colum(row, col data)
      col += 1
  
  workbook.close()
  </code></pre>
  
  <p>I get the error: </p>
  
  <p>AttributeError: 'list' object has no attribute 'tell'</p>
  
  <p>Thanks in advance!</p>
