Note that CSV files are perhaps 10 times slower to process than binary files. They are for data interchange with other languages or when human-readibility or editability is important. If you want speed, use binary format files, e.g.
DataInputStream or possibly the convenient but slower ObjectInputStream.
For example, CSVAlign aligns the fields in columns for easier proofreading.
java.exe -jar csv.jar somefile.csv
CSVPack removes all unecessary spaces to make at CSV file as compact as possible.
java.exe -jar csv.jar somefile.csv
CSVSort sorts CSV file case sensitively, insensitively or numerically on a set of columns, ascending or descending

java.exe -jar csv.jar somefile.csv
