title: How can I solve my problem in Apache Poi and Excel
body: <p>I am using Apache Poi and Java for Excel manipulation. I have modified some of the cell in Excel file by programmatically using Java.</p>
  
  <p>After that, when I open that Excel file manually for seeing that update. After seeing, when I try to close the Excel file it again ask me like "do you want to save the changes you made to test.xls file.</p>
  
  <p>If I press yes button, then only I can able to read the formula cell values programmatically further. Otherwise, if I access the formula cell value it returns 0 value.</p>
  
  <p>How can I resolve this problem?</p>
