cannot Open .Xlsm file


I am trying to open xlsm file, but I got the following error. Please refer to the attached screen shot for the exception details.

The code I used to open is as follows:
_iwb = ExcelEngine.Excel.Workbooks.Open(file, ExcelOpenType.Automatic, ExcelParseOptions.DoNotParseCharts | ExcelParseOptions.DoNotParsePivotTable);

The weird thing is when I add one sheet from the excel book, then the book can be opened.

Sorry, it's when I delete some sheet from the excel book, not add.

Hi Xing Zhou,

Thank you for using Syncfusion products.

We are unable to reproduce the abvoe reported exception at our side. Could you please update us with the excel file or the simplified sample which reproduces the above reported exception so that we are able to proceed further on this.

Hi Sridhar.S,

I think that exception should be thrown by the excel engine. Do you have more information on that exception, for example, under which condition, that kind of exception will be thrown?

Also, I reviews other posts here related to excel book opening. Some technician from Syncfusion mentioned that sometime the structure of the our excel book is damaged although microsoft excel can open it as well. I am wondering if you have any utility to test if the intending open file is intact or not.

Hi Xing Zhou,

Thank you so much for the update.

From the above given image the "Parameter name: relation" is used in many places with XlsIO source library, so we are unable to find out the actual cause of the issue at our side.
Please get back to us with the following details to proceed further on this issue.

1.The excel template file which causes the above reported exception
2.Complete stack trace for an exception
3.From which source the excel template was created (XlsIO or Microsoft Excel)?

Please let me know if you have any further clarifications.
