Excel worksheet error

I am trying to create dyna开发者_StackOverflowmic excel sheet, with the help of php using XML Spreadsheet. But when I try to open the dynamically created excel sheet I keep on getting error that says 'Unable to load worksheet, problem with worksheet settings'. When I try to look at the log file it had created it shows the below text,

XML ERROR in Worksheet Setting
REASON: Bad Value
FILE:   C:\Documents and Settings\UserName\Local Settings\Temporary Internet Files\Content.IE5\5XZ039FS\output[3].xls
GROUP:  Worksheet
TAG:    Table
ATTRIB: ExpandedRowCount
VALUE:  4

Can anybody tell what does the above error mean and how do I remove it?

Without seeing a sample of the xml that you're trying to open in Excel or the PHP code that you used to create it, I'd guess that you specified 4 for the ExpandedRowCount attribute when in fact you have more than 4 rows of data.

Documentation:

ss:ExpandedRowCount

Specifies the total number of rows in this table without regard for sparseness. This attribute defines the overall size of the table, if the specified rows and columns were expanded to full size. If specified, this attribute must be in sync with the table. Row indices in the table should begin at 1 and go to ExpandedRowCount. If this value is out-of-sync with the table, the specified XML Spreadsheet document is invalid.
