CREATE EXCEL IN SERVER

Question

Hey Developers,

 

I will jump straight to the point, i want to create a excel file on the server, the scenario is i have textwriter instance which contains HTML String. Now, using this html string i want to create a excel(.xls or xlsx) file on the server. I tried EPPlus, NPOI but no luck as these all require a properly generated excel file, but here i have html string to pass, so i'm looking for something where it can take html string and then append it with .xls so that it can be open in workbook on the server by which i will be able to generate proper excel means i will be able to 'save as' to .xls or .xlsx format . i tried using itextsharp too but i faced many css issues. 

 

Your insights on this will be very much helpful.

 

Regards
