title: Google Sheets: How to replace text in column header?
body: <p>I have a query like this <code>=QUERY(B2:C9; "select (C  * 100 / B) - 100")</code> in my Google Sheets. What is displayed as a column header is:</p>
  
  <p><code>difference(quotient(product(100.0()))100.0())</code>.</p>
  
  <p>I want to put a human readable description there instead.</p>
  
  <p>How can I achieve this?</p>
