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 com.mindprod.csv.CSVAlign somefile.csv
CSVPack removes all unecessary spaces to make at
CSV file as compact as possible.
java com.mindprod.csv.CSVPack somefile.csv
CSVSort sorts
CSV file case sensitively, insensitively or numerically on a set of columns, ascending or descending
CSVTabToComma converts a tab-separated file to a comma-separated one.
java com.mindprod.csv.CSVTabToComma somefile.csv
