XLSX.read porgress

[Sangpil-Yoon]

reader.onprogress = (progressEvent) => {
//progress
this.progressRate = parseInt((progressEvent.loaded / progressEvent.total));
const fileData = reader.result;
const wb = XLSX.read (fileData, { type: 'binary' });

wb.SheetNames.forEach((sheetName) => {
const rowObj = XLSX.utilssheet_to_json (wb.Sheets[sheetName]);

this.expelDatapush(JSON.stringify(rowObj);
});
};

Progress is not working properly.
Progress acts after XLSX.read.
If you change the location of the progress, you can still do so.

I need your help.
