I get the below error message when I attempt to add a new worksheet to / copy cells from an Excel 2013 .xlsx file generated in browser.
Paramquery Pro v3.4.0
Javascript:
var blob = this.instance.pqGrid("exportData",
{ format: "xlsx", render: true, sheetName: "Page 1" });
if (typeof blob === "string") {
blob = new Blob([blob]);
}
saveAs(blob, "test.xlsx");
