Source code to create the error


I am using POI 3.17 final to read an Excel Macro file (xlsm).
There is no error during reading of the file.

Afterwards I read some sheets data and write this workbook back to file.
(there is no error during writing to a file, too.)

The written file is now corrupt and Excel, start with Version 20007, must repair the file.

Message: Excel has found unreadable content in file XXX Do you like to repair the Workbook? (Sorry this may be not the original english message, because i use the german Version of Excel). 

Excel try to repair this file and remove some Content.

See attachment for examples. The BugDemo-OUT.xlsm file is corrupt.

source code to test is attached, too.

Thanks in advance for your help.

This file will be created by source code and original Excel Macro file

As a workaround, if you're not modifying the Workbook, can you open it in read only more via the OPCPackage class?

Dear Mr. Javen O'Neal,

alas it is not possible for me.
As you can see in my appended source code 
(method speichereFormularVorlageDaten) , 
i need this to store an additional custom property in the excel macro file. 

Originally, i use a ByteArrayInputStream to read the file by dint of application Server.

The problem seems to be the ListObject inside the Excel macro file.
This is an extension to a QueryTable - Object since Excel 2007. Since an update of Office, the QueryTable - Object will automatically changed to the ListObject.
It is not possible to reverse this automatically change anymore.

Up to now i could not find the cause update.

Best regards

Can you also attach the original file so we can re-run the test-case with it to reproduce the problem?
Comment 6 Uwe Herrmann 2018-01-03 11:32:22 UTC
Dear Dominik Stadler,

you already find an attached file called BugDemo.xlsm to reproduce the error.
The error occurs after you rewrite the file with POI, as you can see by the first attachment.

Thanks in advance for your help!
