const options = {
licenseKey: 'gpl-v3',
};
// define the data
const data = [['10', '20', '30', '=SUM(A1:C1)']];
// build an instance with defined options and data
const hfInstance = HyperFormula.buildFromArray(data, options);
// call getCellValue to get the calculation results
const mySum = hfInstance.getCellValue({ col: 3, row: 0, sheet: 0 });
// print the result in the browser's console
console.log(mySum);
