From time to time some user are getting the message "Excel has found unreadable content in <filename.xlsx>. Do you want to recover the contents of this workbook?" when they open xlsx files from a file server in Excel 2010. When they select "yes", they are told that errors were fixed and am given the following log info:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<recoveryLog xmlns="http://schemas.openxmlformats.org/spreadsheetml/2006/main">
<logFileName>error060920_01.xml</logFileName>
<summary>Errors were detected in file 'Filename.xlsx'</summary>
<repairedRecords summary="Following is a list of repairs:">
<repairedRecord>Repaired Records: Drawing from /xl/drawings/drawing1.xml part (Drawing shape)</repairedRecord>
</repairedRecords>
</recoveryLog>
The file opens and all drawing objects (Text Boxes, Rectangles, Triangles, Straight Connectors) have been removed.
To diagnose the issue I opened the document as zip-archive, browsed to the file "xl\drawings\drawing1.xml" and extracted it. I then opened the file in a web-browser and it reported no errors, then opened it in Notepad++ and checked the XML syntax; both were successful.
I have read KB2384361 'Performance degradation opening Excel workbooks' and confirmed that the Shapes do not contain XML tokens.
Any help on resolving this issue would be appreciated.
