Aspose.Cells Failing to open excel spreadsheet exported from crystal reports

We are attempting to open a excel workbook exported from a legacy version of crystal reports (which opens fine in Excel 2007), but getting the following error (on instantiating workbook object):

Index was out of range. Must be non-negative and less than the size of the collection.

Parameter name: startIndex



Using the following code:

Dim stream As New System.IO.FileStream(“C:\data\BYM_Client_Export1140908.xls”, IO.FileMode.Open)

Dim loadOptions As New Aspose.Cells.LoadOptions(Aspose.Cells.LoadFormat.Excel97To2003)

Dim wb As New Aspose.Cells.Workbook(stream, loadOptions)



Please can you help to explain why the file cannot be read?



Thanks

Hi Matthew,

Thanks for your posting and using Aspose.Cells.

We have looked into your source file namely bym_client_export1140908.xls and opened in MS-Excel 2010 and MS-Excel 2007. Both of them showed error on opening this file. So this file is actually corrupt.

If you will try to open a corrupt file using Aspose.Cells, it will throw the exception as it is throwing in your case.

Please see the screenshot below that displays error in MS-Excel 2010 when your file is opened for your reference.

We have seen the error in Excel 2010, but the file will open successfully in Excel 2007. And we were hoping to use aspose.cells to convert between 2007 (xls) and 2010 (xlsx).

Thanks

Matthew

Hi,

Thanks for using Aspose.Cells.

Please download and try this fix: Aspose.Cells
for .NET v8.0.0.3
.

We have now ignored some invalid records in the file, but it’s better that you can
find why your tool create such file.
