I've tried changing the target CPU to x86 but that appears to make no 
difference.

I'm running Excel 2007 on Windows 7 x64.

Excel 2007 works fine. Excel 2010 has problem.

I have also duplicated this problem, opening the xls file Excel 2007 in Windows 
7 x64.

I can confirm I am running windows 7 x32 and I get the same error message.  If 
I forward it to a co-worker whom is running Windows XP, he can open the file 
with no errors.  We are both running Office 2007 Std Edition.

I have the same problem and maybe found a workaround: I appended some empty 
rows so that there were at least 20 rows and the filesize was at least 7kB. 
Then Excel (2010, on win7 64bit) could read the file.

I confirmed this bug, as well as the fix to add 20 rows. Thank you.

Hi,

I confirmed this bug using the sample code on the project site 
(http://code.google.com/p/excellibrary/).

Adding 75 additional rows to the sample code (which brought the file size up to 
7kb) fixed the issue for me.

Thanks.

On Windows7 x64 Excel2010, I get "Excel found unreadable content in 
'MyExcelFileExcelLibraryDataSetHelper.xls'. Do you want to recover the contents 
of this workbook?  If you trust the source of this workbook, click Yes."  Then 
I click Yes, and the document does not load.

When I made a sheet with 100 rows of Numbers, it was large enough to work, when 
I made a sheet with 99 rows of Numbers, it gave the "Excel found unreadable 
content" warning.  When I added a second column of numbers it would wok with 
only 61 rows, but not with 60 rows.  (I'm using DataSetHelper.CreateWorkbook(), 
so the first row is always the string of the column labels)

The problem is actually in the FAT table.
first record should not be 0xfffffffd

Count = 0x00000080
    [0x00000000]: 0xfffffffd
    [0x00000001]: 0xfffffffe
    [0x00000002]: 0x00000004
    [0x00000003]: 0xfffffffe
    [0x00000004]: 0xfffffffe
    [0x00000005]: 0xffffffff
    [0x00000006]: 0xffffffff

btw, you can replicate it with an empty workbook too.

Hello guys,I'm having the same problem, but I dicovered a workaround to fix 
this problem. In my opinion, it's bizzar. The major problem is the output file 
is too small, less than 10KB. So, if you increment your sheet with more lines 
and columns with a space, you'll be able to open the file normally.

Best regards.

My workaround was to switch to NPOI

Can confirm this is still present and causing problems here.
If flood to over 7k then loads fine in Excel2010, less than this and still get 
unreadable content error. Same XLs loads fine in Excel2003.

This is still present in my case as well.

Ok, I had the same issue. 

My solution:

I inserted 200 empty rows, then the file is bigger than 10 kb, now it's working 
fine. 

Thanks everyone.

Yes, comment 24 is right, I also inserted 200 empty rows... then the file is 
correct.

BUT: if I open a "large" 500KB excel file, and just save it (whithout any 
modification), the result: The file is unreadable...

Issue 131 has been merged into this issue.

Same problem on Window 7 for Office 2010.
File is corrupt while in OpenOffice it works perfectly.

After adding 100 rows and save it for the > 20kb size, I ended with a size of 
8KB and now works in Office 2010.

A fix for this is nice to have but not necessary for me.

Thanks for the great plug-in!

is there any way to fix this problem without hacking the system and adding 75 
empty rows. Any help would be greatly appreciated.

I can open this file on Window 7 for Office 2010,
After adding a loop with random text, make capacity bigger 10KB, you can open 
it.
