"too many fields defined" error when previewing xls

Anyone know why I am getting this?

===================================

There was an error displaying the preview. (Microsoft Visual Studio)

===================================

Too many fields defined. (Microsoft JET Database Engine)

Program Location:

at Microsoft.SqlServer.Dts.Tasks.ExecuteSQLTask.Connections.SQLTaskConnectionOleDbClass.ExecuteStatement(Int32 resultType, Boolean isStoredProc, UInt32 dwTimeOut)
at Microsoft.DataTransformationServices.Design.PipelineUtils.ShowDataPreview(String sqlStatement, ConnectionManager connectionManager, Control parentWindow, IServiceProvider serviceProvider, IDTSExternalMetadataColumnCollection90 externalColumns)
at Microsoft.DataTransformationServices.DataFlowUI.DataFlowConnectionPage.previewButton_Click(Object sender, EventArgs e)

A wild stab in the dark: You have to many fields? How many do you have? A clue would help determine if it is a problem of indeed a limitation..|||31 columns on the sheet that I am importing from.|||Obviously 31 is not to many. You have 31 columns with data in. Do you perhaps have any columns with a space or some other text in it right at the end of the document. Like at column ZZ?

I can create a sheet with 32 columns in it and it is fine. Adding spaces to columns after that causes the same error.

I suggest copying the columns you want out, pasting them in a new sheet and try that.|||the sheet has autofilter set on, could that be the cause?|||I don't know. Remove it and see.
