I have a CSV template file, say, having 10 columns.
I would like to load this CSV file template, and then write data to the relevant cells(say only to 5 of the 10 cells) through a java program. 
I went through [JSAPAR](https://github.com/org-tigris-jsapar/jsapar), [SuperCSV](https://super-csv.github.io/super-csv/index.html) etc, but am not sure whether these libraries have the "stuff" what exactly I need.
Is there any framework supporting this kind of operations?
