Unable to export Bar graph to EXCEL sheet

I am using ant design Bar graph , I am trying to export Bar graph to excel worksheet.
I tried to convert <Bar/> from UI to Object using html2canvas.

Currently I am getting the converted image URL instead of actual bar graph Image in the excel worksheet cell. Like below…

data:image/png;base64,iVBORw0k......

And I can see the actual bar graph image after visiting above URL in browser.

const exportToExcel=()=>{
    const workbook= XLSX2.utils.book_new();
    const chart = document.getElementById('myChart');
        html2canvas(chart).then((canvas) => {
          const imgData = canvas.toDataURL('image/png');
          const worksheet = XLSX.utils.aoa_to_sheet([['Chart'], [imgData]]);
          XLSX.utils.book_append_sheet(workbook, worksheet, "Chart");
          XLSX.writeFile(workbook, U_${formattedDate}.xlsx, { compression: true });
        });
      };
