Convert xlsx file and formula into a JS API

Budget €8 - €30 EUR
Bids 11
Average Bid €61

We currently use an excel spreadsheet to make some function and calculate everything thru formula and multiple sheet.
We would like to port it on the web in order to ease the process.

We just need to transform the formula part in a sort of JS API, that will be called by the website.
So basically we want you to create a JS file with namespace and separate function. Private function should do the logic and public function should be called to get result.

We could provide basic prototype and excel spreadsheet in order for you to get a clear picture of the project.

This is a one time schedule thing.

    I am an experienced computer programmer working freelance full time, specializing in C/C++ and PHP/Javascript languages. Desktop Apps (Windows/Linux), Games, Web Dev, Wordpress, Arduino. My areas of expertise: -portable Linux/Windows software in C/C++ FLTK, SDL or Qt depending on the task. -game programming: C/C++, Javascript, HTML5, Flash/Actionscript, Cocos2d-x, experience in Unreal Engine. -Web programming using modern OOP techniques with PHP/MySQL/Javascript and jQuery. -Programming the arduino board based on the Atmega328p processor. Linux is my desktop OS and I am best at writing portable C/C++ code that works both in Linux and Windows. This is possible thank to free portable libraries like FLTK, SDL, Qt and such. Doing freelance job since February 2012 (on vWorker). My preference is to do small projects (up to a month). Among other things, I have experience writing a library to open unusual file format like ZVI - image file format used in Zeiss digital microscopes. My another was a GUI Windows app to control fireworks modules connected to the network using udp protocol. Lots of small projects such as simple games like Lunar Lander, a "simple C++ text game" and so on. Also I program websites using PHP/MySQL, have quite a bit of professional experience integrating PayPal, Sagepay, Google and Facebook login, a lot of Google maps API jobs, including some advanced ones. I use object-oriented approach in PHP, can work projects from scratch without (or with) dependence on CMS like WordPress, or any of php libraries like CodeIgnite or CakePHP. In Javascript, I tend to use jQuery a lot, but can work without it if necessary. Fixing broken css/html/javascript/php code is also one of my strong sides. I have developed quite a few wordpress plugins and themes (only the programming part), ranging from simple shortcode plugins to complex interactive graphical editors, such as product customization and shopping carts with paypal integration. I've also wrote some stand-alone one-pager product sites with paypal integration and email notification - with quick turn around. Born in 1981 in Almaty, Kazakhstan, lived 15 years in Canada and hold a Bachelor Degree in Music from Universite de Montreal. Currently living back home in Almaty, Kazakhstan.
