[PENDING] Exporting data to files (which plugins ?)

[eluser]Morty[/eluser]
Hi there!

I am quite successful in building my first CI application, and since I now have good results coming from my database, I would like to export them to Excel-readable files. There seems to be plugins/libraries to export QUERIES (or query results) directly to CSVs (or XLS) but I want to modify some of my results before sending them to CSV files.

- Is it possible to change query results, like adding columns and entries ?
- Which libraries / plugins are available to export data ?

Thanks in advance,
Morty
