                values.map((v) => workbook.sheet(v.sheet).cell(v.cell).value(v.value))
                const wbout = await workbook.outputAsync()
                const blob = new Blob([wbout], { type: 'application/octet-stream' })
                const fileName = `test_${new Date().getTime()}.xlsx`
                saveAs(blob, fileName)
            })
    }

    document.querySelector('#btn').addEventListener('click', () => {
        const url = './test.xlsx'
        const values = [
            { sheet: 'Sheet1', cell: 'D4', value: document.querySelector('#D4').value },
            { sheet: 'Sheet1', cell: 'D5', value: document.querySelector('#D5').value }
        ]
        exportExcel(url, values)
    })
</script>

上記htmlを作成して、同じ階層に「test.xlsx」を作成しておく。
