title: SQL Developer - Retaining data values when exporting data
body: <p>I'm running a query on a table that has a <code>VARCHAR2</code> column with alphanumeric values (Ex. 234E0971, 2560D1A3, 38BC912E).</p>
  
  <p>When I export the selected data into Excel, some of the values in that column are converted to scientific notation and when I change it back to a text it is a different value than what it originally was in the data table. For example, '282845E5' becomes '2.83E+10' in the exported Excel file and when its format is converted it is '28284500000'. </p>
  
  <p>This doesn't happen for every value in that column, only some of them, but it's enough to be a problem.</p>
  
  <p>Does anyone know why this is happening or what I can do to prevent it from happening?</p>
