grid.import.xlsx found no worksheet in the .xlsx; nothing to import.

What happened

The file inflated and parsed, and the workbook names no worksheet the importer can reach. An empty result is returned: no header, no rows, no sheet name. A workbook whose only sheet is a chart sheet looks like this.

The fix

Check the workbook in a spreadsheet application; the importer reads the first ordinary worksheet.
