title: Check file existence with formula in excel
body: <p>I have this requirement of creating hyperlink only if file exists at the location.
  as each file name will be different fetched from cells after entering data.</p>
  
  <p><code>=IF(NOT(ISBLANK(J10)),HYPERLINK(O6&amp;J10&amp;".jpg", "Bill Available"),"")</code></p>
  
  <p>I have this formula, which creates hyperlink as soon as i enter something in "J10" and creates hyperlink to path "O6" and file name "J10". Nut I dont want it to create hyperlink if file is not there... I'm thinking of using "AND" with "IF" but how to check file existence?</p>
