Nick Burch commented on TIKA-1490:
----------------------------------
Codepage support is in there now, as is something similar for Excel 5 / Excel
95. No format string support though, will need a little bit more work on the
old style records to add it in if someone wants it
When we upgrade to POI 3.11 final, we can add a parser based on this for Excel
2-4, and call to it from ExcelExtractor when it detects a Excel 5-95 file
> Basic parser for old Excel files (eg Excel 4)

> Key: TIKA-1490
> URL: https://issues.apache.org/jira/browse/TIKA-1490
> Project: Tika
> Issue Type: Improvement
> Components: parser
> Affects Versions: 1.6
> Reporter: Nick Burch
> Assignee: Nick Burch
>
> In TIKA-1487, we added mime magic for the pre-OLE2 excel file formats. Based
> on the reading of the OpenOffice Excel docs for that, it looks like it should
> be possible to produce a basic parser to extract key bits of info (eg
> strings) from these older file formats.
> This would likely largely be done by having a custom record iterator for the
> older formats, then passing the handful of "interesting" records to POI's
> record classes (maybe with some tweaks for the older formats) to have the
> binary data parsed, then returned by the parser
