Hi all, this is my first time posting and I am having a problem in researching how to combine XLS and HTML into a XLSX.
I would like to avoid using Excel directly to create excel file (using OLEDB Automation or Excel Interop objects). Ideally I would like to use any open source class libraries with some documentation and samples.
Here is the scenario I would like to achieve:
User has one large XLS file and multiple HTML files with tables (I cannot change this).
Depending on some user selections I need to generate new XLSX file (I can change this into XLS) from a part of the specific XLS sheet and from an HTML file which has a same name as that sheet.
Any guidelines would be appreciated, if possible please provide some links or snippet codes for any of required task.
Thank you in advance.
