In my case I was getting the follwoing error:-
XML ERROR in Workbook Setting
REASON: Too many tags
FILE: C:\Documents and Settings\mylogin\Local Settings\Temporary Internet Files\Content.IE5\KTEZW9ER\PCAPAnalysis[1].xls
GROUP: Workbook
TAG: Worksheet
ATTRIB: Name
VALUE: Detailed Report

It does not come up anymore since I changed the name of the file to a dynamically generated random number in the contentdisposition header of the response. I have a web application and having the same filename in the response header some how gave teh above error.

I also cam across this error while trying to use the CarlosAg.ExcelXmlWriter.

I had multiple sheets in a workbook, which were named uniquely, but I then added a style, and style names must be unique for each worksheet as well.

I ended up appending the worksheet name to the style name.

I ran into something similar from a .xml written by Excel 2003.

XML ERROR in Style REASON: Too many tags FILE: MyFileName.xml GROUP: Styles TAG: Style ATTRIB: Name VALUE: Normal

Turned out that two Style elements had the same ss:Name attribute values. Both “Default” and “s21″ had ss:Name=”Normal”.

I got rid of one of the name attributes ( the one on the Default Style) and Excel read again. Upon re-writing, the second “Normal” was magically changed to “Normal_”.

By removing the nameless ‘default’ tag, I meant.

My errors were:

XML ERROR in Style REASON: Bad Value

XML ERROR in Style REASON: Too many tags

Solved them by removing the tag at the beginning of the XML.

This happened to me recently with a monsterous spreadsheet that had a duplicate ‘Default’ style (two entries with the same Id tag seems to be the trick). When I exported it, there were two ‘Default’ styles in the tag, causing an error when re-opening the XML file. Removing it from the XML eliminated the problem. Now I just have to figure out how to get rid of this odd style.

I got this error when adding cells to a worksheet but not ‘trimming’ the strings correctly. Adding the cells would work if I did it with a bit of test data statically in the code but when I referenced real data from a row in a dataset I had to ‘trim’ the strings with the VB.NET function ‘.trim’. Perhaps it’s my particular data but it’s worth mentioning.

Yes, that's correct for one bad defined XMLExcel file. But I get this issue when my website export one XMLExcel file with 5 Sheets.

If I save this file to local storage then open it - this issue never occurs. But I chose directly open this file then sometime this issue occur.

Have you got any idea?

Thanks & best regards,
