title: Run a query from two data sets programmatically
body: <p>I am trying to reconcile data from a website and a database programmatically. Right now my process is manual. I download data from the website, download data from my database, and reconcile using an Excel <code>vlookup</code>. Within Excel, I am only reconciling 1 date for many items.</p>
  
  <p>I'd like to programmatically reconcile the data for multiple dates and multiple items. The problem is that I have to download the data from the website manually. I have heard of people doing "outer joins" and "table joins" but I do not know where to begin. Is this something that I code in VBA or notepad? </p>
