I make a button that downloads a table in an xslx format, but when opening the file it says "this document cannot be opened, apparently the sheet is damaged".
function exportTableToExcel(tableID, filename = ''){
var downloadLink;
var dataType = 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet';
var tableSelect = document.getElementById(tableID);
var tableHTML = tableSelect.outerHTML.replace(/ /g, '%20');
// Specify file name
filename = filename?filename+'.xlsx':'excel_data.xlsx';
// Create download link element
downloadLink = document.createElement("a");
document.body.appendChild(downloadLink);
if(navigator.msSaveOrOpenBlob){
var blob = new Blob(['ufeff', tableHTML], {
type: dataType
});
navigator.msSaveOrOpenBlob( blob, filename);
}else{
// Create a link to the file
downloadLink.href = 'data:' + dataType + ', ' + tableHTML;
// Setting the file name
downloadLink.download = filename;
//triggering the function
downloadLink.click();
}
}```
