I am using the current version of the Buttons extension. When I produce an Excel document from the Excel button plugin, I got the following error from Excel when opening the document:
"Excel completed file level validation and repair. Some parts of this workbook may have been repaired or discarded.
Repaired Part: /xl/worksheets/sheet1.xml part with XML error. Catastrophic failure Line 1, column 0."
This error only occurs when I suppress the title in the Excel output (and do not have a footer).
{
extend: 'excel',
title: null,
}
If I do add a footer, the problem goes away. It seems that the issue is with the mergeCells tag being present when no cells are being merged. In fact, if I delete this line, then the issue is resolved.
I wanted to report this bug and see if there is any way to work around it without editing source code.
Thank you!
