Recently I had to write some software for the company I’m working for. It’s web application for converting raw exported data from Oracle database to human readable excel file. And it’s not naive app. Not at all. I am still responsible for cca 200.000 entries and upper top management makes decisions relying on this app. So it’s serious.

updated: problem solved long time ago, I can’t remember what was it. I think I did convert data from the php end. That way mysql tables left intact.
