title: Why Pandas ExcelWriter is truncating a dataframe's cell content?
body: <p>One of the cells' value in a dataframe is a very long string. When pandas writes it to an excel sheet, that value is getting truncated. Any reason why? Below is my code snippet.</p>
  <pre><code>excel_path = './{}_somename.xlsx'.format(name)
  options = {'strings_to_formulas': False, 'strings_to_urls': False}
  writer = pd.ExcelWriter(excel_path, engine='openpyxl', options=options)
  for df_name, df in df_dict.items():
     df.to_excel(writer, sheet_name=str(df_name), startrow=0, index=False)
  writer.save()
  
  </code></pre>
  <p>example of the very long string inside the cell: <code>&quot;asdasdas&amp;reg; aadsdas Psgdfgjj (4 hgjhj, 4r A77 @1.20 erer)|Ahjdks A7373X Hkjnksds (9 Djhks @ 1.50YUx)&quot;</code>. Actual string could be 10,000,000 chars long.</p>
  <p>Note: For confidentiality reasons, I cannot share the exact string.</p>
