title: Reading .xlsx in java
body: <p>I've read every single question here and couldn't find the easy answer.</p>
  
  <p>What I need is just 1 .jar, which I will add into my project in Eclipse. Then I just want to import it and use a library that can extract data from .xlsx file.</p>
  
  <p>Apache POI needs a lot of .jar files. It crashes and throws a lot of exceptions that don't make sense.</p>
  
  <p>Smartxlsx has absolutely no documentation and it's horribly hard to use/understand it. </p>
