Projects / Flat File Extractor

Flat File Extractor

ffe is a flat file extractor. It can be used for reading different flat file structures and displaying them in different formats. ffe can read fixed length and separated text files and fixed length binary files. It is a command line tool developed under GNU/Linux. The main areas of use are extracting particular fields or records from a flat file, converting data from one format to an other, e.g. from CSV to fixed length, verifying a flat file structure, as a testing tool for flat file development, and displaying flat file content in human readable form.
