I'm looking for a library to generate excel files. It is not just about outputting csv, or some rows, but about a library which would also make easier to do some basic formatting like header rows, changing colors and font size.
There are many excel generation libraries for the server, but I cannot find anything more than some examples on how to write it myself. There is a library going in this direction: https://jordiburgos.com/post/2017/excellentexport-javascript-export-to-excel-csv.html But it's more for generating excel based on tables in HTML. And in addition, it doesn't cover more advanced topics like those I mentioned.
