title: replace space with comma for words that only have space between them regex
body: <p>I trying to replace spaces with comma for words that only have space between them
  like this example</p>
  <blockquote>
  <p>Color  :  NavyBlue      TrainLength : FloorLength  USSize : 6   shipping
  : standard</p>
  </blockquote>
  <p>it should be like this</p>
  <blockquote>
  <p>Color : NavyBlue,TrainLength : FloorLength,USSize : 6,shipping :
  standard</p>
  </blockquote>
  <p>where it has  commas between these variants</p>
  <p>I can only match spaces between words that have colons</p>
  <pre><code>\s*:\s*
  </code></pre>
  <p>but I need a way to match spaces between words that has no colon</p>
  <p>for example  consider the dots as space</p>
  <blockquote>
  <p>don't match this ...:...</p>
  <p>but match this NavyBlue.....TrainLength</p>
  </blockquote>
  <p>match the spaces only not the words</p>
