Jukka Zitting resolved TIKA-189.
--------------------------------
Resolution: Fixed
Fix Version/s: 0.3
Assignee: Jukka Zitting
I believe that this is a regression from Tika 0.2. It looks like the more
recent POI version we're using has switched to zero-based indexing of rows and
columns, which caused Tika trunk to concatenate the values of the first two
cells on a row.
This is now fixed (for .xls) in revision 737581. See TIKA-152 for .xlsx support.

> Pro SP3, JDK version is 1.6.0_06.

> I plan on using Tika to extract text from Excel (both .xls and .xlsx) files
> for indexing. But, I found that Tika juxtaposes cells on output. The example
> worksheets are in the attached .zip file.
> I took the time to run Apache POI and it does not have this bug i.e. cells
> are properly separated.
> When I run
> --begin--
> java -jar tika-0.3-SNAPSHOT-standalone.jar --text
> no_cell_separators_when_extracted.xls
> --end--
> I get the following output:
> --begin--
> Plan1
> NameEmailSanta [email protected]
> Tooth [email protected]
> --end--
> Same thing with a .xlxs file:
> --begin--
> java -jar tika-0.3-SNAPSHOT-standalone.jar --text
> no_cell_separators_when_extracted.xlsx
> --end--
> The output is:
> --begin--
> [Content_Types].xml
> _rels/.rels
> xl/_rels/workbook.xml.rels
> xl/workbook.xml
> xl/theme/theme1.xml
> xl/worksheets/_rels/sheet1.xml.rels
> xl/worksheets/sheet2.xml
> xl/worksheets/sheet3.xml
> xl/sharedStrings.xml
> NameEmailSanta [email protected] [email protected]
> xl/styles.xml
> xl/worksheets/sheet1.xml
> 012345
> docProps/core.xml
> GeorgerGeorger2009-01-17T15:29:04Z2009-01-17T15:30:56Z
> docProps/app.xml
> Microsoft Excel0falsePlanilhas3Plan1Plan2Plan3falsefalsefalse12.0000
> --end--
> Also note that the values from docProps/app.xml have been juxtaposed as well.
> This way, after indexing these files using the output from Tika, a search
> engine will only find "Fairy" when substring matching is used, because "Tooth
> Fairy" becomes "Tooth [email protected]". This is suboptimal and wrong.
> Thanks for your attention. Best regards,
> Georger
