Re: [Quantlib-users] New aprroach for a QuantLib/Excel add-in

[Eric E. <eri...@re...>]

Hi Sebastian,

We are curious about this project and I will take a closer look at it 
when I can.  Do you provide backward compatibility with existing 
QuantLibXL spreadsheets?  Under the hood, how does xloil interface with 
Excel?  I took a quick look at the documents, the answer to my question 
was not immediately obvious to me.  It seems like it does not use the 
Excel C API.  Do you know how your build compares to QuantLibXL 
performance wise?

I updated the QuantLibAddin readme to include a link to your project:

Regards,
Eric
