We are trying to use latest aspose cell dll in our solution since last 3 releases. (jan-2013 to march 2013).
Right now we are using 18.104.22.168 and we need to use latest version to address the issues fixed in it.
But workBook.save options results into regression issues every release.
Till Jan -2013 release (22.214.171.124) we were able to see output with small issues in HTML. (Like comma is missing in number format.)
And in March - 2013 we are not able to see HTML output itself.
I have attached output of same excel file in 3 version which will help you to compare.
Please let me know if you need more details.
