      Steps to reproduce:

      1. Create an Excel spreadsheet and enter some text in a cell
      2. Select part of that cell and change its formatting (e.g. bold, italics, underline)
      3. Save this spreadsheet and upload to Confluence
      4. Rebuild search index

      Error in logs:

      2011-10-02 14:23:25,893 ERROR [Indexer: 1] [officeconnector.index.excel.ExcelXMLTextExtractor] endDocument expected [ 1 ] entries but read [ 2 ]
 -- referer: http://localhost:5350/admin/search-indexes.action | url: /admin/reindex.action | userName: admin | action: reindex

      An example .xlsx is attached.

      Here are the contents of sharedStrings.xml when the .xlsx is unarchived, which appears to contain the relevant data:

            I have two questions about this bug that I hope someone can answer.

            1) It appears at least part of an Excel document with mixed formatting in a single cell is indexed. However, some text is not indexed. From testing, it's not clear what will and will not be indexed due to this issue. Does anyone know what will and will not be indexed in an Excel document with mixed formatting?

            2) Does one indexing error message in the log pertain to one file? Or can one error message be in regards to x files (where x is greater than 1)?

            We see this error quite often in our logs, version 5.4.3.
            This is 5th bug/problem we see after upgrading to 5.4.3. Most cases have been open for quite some time and recommended solution from community on all of them is to simply filter out log entries so we don't see them. Doesn't really inspire a lot of trust in the bug solving process at atlassian.

            As a workaround to have not all that noise in the log file I added this at the end of the file \confluence\WEB-INF\classes\log4j.properties

            # CONF-23376
log4j.logger.com.atlassian.confluence.extra.officeconnector.index.excel.ExcelXMLTextExtractor=FATAL

            Of course this does not solve the root cause of the issue...
