Hey there,
I have gone through your requirements, I will be able to provide you the conversion of excel formulas to in PDF using JavaScript.
I run a company specializing in JavaScript development. In the last two years, I've automated workflows of several of our clients using JavaScript. I am confident in being able to deliver your requirements.
I'm just starting out at freelancer here so I have kept a very low bid as I am doing this for the rating and not the money.
Please feel free to write back if you have any questions...
