title: Excel: Change "," to "."
body: <p>Ever since i added a multiple language option for my computer, Excel decided to turn all my decimals into commas. I need to turn them back into decimals again. How do i do this with least amount of work? If you know an EASY way to do this, emphasis on easy, please tell. When it is converted, i need a number, not text or anything else. I'm using Microsoft Office Professional Plus 2010.</p>
  
  <p>I tried the approach where you make this formula in Excel</p>
  
  <pre><code>=SUBSTITUTE(A4;",";".")+0
  </code></pre>
  
  <p>Which should, i'm assuming, get cell A4, change comma into period and then by adding 0 convert to number. My original number is 17.6, now i'm getting 41807.</p>
