title: convert excel file to html and javascript
body: <p>i have one excel calculator file which contains several sheets and formulas searching across sheets.</p>
  
  <p>i want to convert this calculator in html page, and using javascript to do the calculation.
  I've built up mySQL database to store these data for lookups...using php forms should get user inputs</p>
  
  <p>I am concerned with the logic and layout in excel is not so straightforward as in javascript using functions. </p>
  
  <p>Is there a way to do this that ensures the accuracy?</p>
