QueryCSV

enable you to load CSV files and manipulate them using SQL queries then after you finish you can export the new values to CSV file

Why

it's started with this task that I need to merge 30 CSV file into one file and group it by day instead of the hour, I wrote a couple of lines of code to do that, but I knew it is not going to be the last task that I will need to manipulate the CSV files, so wrote this cmd app to help me on this kind of tasks, I hope that could help too.
