title: COUNTIFS with LEN and more conditions
body: <p>Is there a way to use COUNTIFS with LEN and more conditions. I want to count all rows that have a true value in column C and where the string in column B has a length of 17. So something like the snippet below but where the <code>LEN()=17</code> condition actually works</p>
  
  <pre><code>COUNTIFS(Database!C:C;"=TRUE";Database!B:B;"LEN(Database!B:B)=17")
  </code></pre>
  
  <p>I am aware that I could use ARRAYFORMULA as suggested in <a href="https://stackoverflow.com/questions/18740532/countif-with-len-in-google-spreadsheet">Countif with len in Google Spreadsheet</a> but try to do this without an additional column.</p>
