title: Excel 2010: Open a file that contains more than 1M rows?
body: <p>I have an excel file provided in .xlsx format. The person who sent me the file states that there are over 1.2M records contained in the file. However, when I open up the file, I see a little over 1M records. I was instructed to open the file in Notepad, save as a .txt file and then I will be able to view all 1.2M records. </p>
  
  <p>Is this possible for .xlsx files? I've done some research that states this is possible for .csv files but am wondering if I need to request a .csv file or .txt file that actually contains all of the records. </p>
  
  <p>Thanks in advance for your help.  </p>
