You may use the script language Perl which is available for free for many
platforms.
You then have to install several modules which allow to access Word,
Excel, PDF, SQL,
Zip, Tar, ...

Google for Perl, CPAN, ActiveState ...

If you do so, please tell me of your experience.

Subject
Text Extractor






Hello,

I am looking for a text extractor (tool set) which could be used, to get
text data out of several file formats like office documents and so on. The
text data (extract) could then be used to index with lucene. Best would
be a java api, but not required. Does any one have knowledge of such a
tool set or project?

Best Regards

Stefan

The Tika project [1] in the Apache Incubator is currently getting
started at implementing such a generic toolkit. Unfortunately we
haven't yet released anything.

You may also want to check out the Lius project [2] that is one of the
source codebases to be used in Tika. Another potential match is the
Aperture project [3].

[2] http://sourceforge.net/projects/lius/
[3] http://aperture.sourceforge.net/

It might be worthwhile for you to review Nutch, a web search application
based on Lucene that can also search local filesystems. It includes parsers
for several common office type documents.
