title: Filter by string length (number of characters)
body: <p>I am currently working with a table that contains a code in one column and its description in another. The bigger (longer) the code, the more specific its description. For example: </p>
  
  <pre><code>1     = Personal expenses.
  1.1   = Personal services associated with payroll.
  1.1.1 = Salaries of the people in the payroll.
  </code></pre>
  
  <p>I want to select only the rows of the table that have a maximum of <strong>3</strong> digits (not counting full stops) in their code. Using advanced filters in Excel, I tried to use a couple of wildcards defined on the code column, that is <code>?</code> OR <code>???</code> as needed in different rows. </p>
  
  <p>However, this advanced filter seems to take the wildcard as a reference of the minimum number of characters to be included in the final table, so I end up with the same list I had to begin with.</p>
  
  <p>When removing one condition, and using only <code>???</code> I end up with the list:</p>
  
  <pre><code>1.1   = Personal services associated with payroll.
  1.1.1 = Salaries of the people in the payroll.
  </code></pre>
  
  <p>Thus confirming what I had already thought.</p>
  
  <p>Does anyone know how I can appropriately filter this table the way I want to?</p>
