TextZilla is a Multithreaded Java utility which can process huge size delimited text files to extract, convert, encode, decode, encrypt/decrypt text data from source and write it in desired output file or files.

It provides fully extensible framework based on which Java classes can be created, for example it currently has MD5 conversion capability, based on same design classes for 3DES ,AES or any other Algo can be created.

Another strength of this tool is in its configurability, it's design allows to generate as many output files as required from one input file, and at every row of input file validation, extraction, conversion can be applied.

Use case Example: legacy system is to be replaced with new advanced system with different DB schema, and the data provided as 100GB size of delimited text data which is to be inserted in 10 different tables of new system DB after validation,date format conversion, rearrangements, and MD5 hashing implementation.
