Flat file extractor can be used for reading and parsing different flat file structures and printing them in different formats. ffe is a command line tool developed in GNU/Linux environment and it is distributed under GPL.
Timo has been very responsive on requests for help. It's very fast and it is good at parsing large data sets that have non-standard inputs and outputing them in a more standard format or generating more report-like output. Looking forward to a little more control on translating/splitting/merging output data or "record-oriented" operations.
no trouble to install and run, works nicely.
