Once installed, you can use it to develop applications tailored to your specific business needs. Here, we've used it to craft a form that calculates mortgage payments using the PMT formula.

import { HyperFormula } from 'hyperformula';

// Create a HyperFormula instance
const hf = HyperFormula.buildEmpty({ licenseKey: 'gpl-v3' });

// Add an empty sheet
const sheetName = hf.addSheet('Mortgage Calculator');
const sheetId = hf.getSheetId(sheetName);

// Enter the mortgage parameters
hf.addNamedExpression('AnnualInterestRate', '8%');
hf.addNamedExpression('NumberOfMonths', 360);
hf.addNamedExpression('LoanAmount', 800000);

// Use the PMT function to calculate the monthly payment
hf.setCellContents({ sheet: sheetId, row: 0, col: 0 }, [['Monthly Payment', '=PMT(AnnualInterestRate/12, NumberOfMonths, -LoanAmount)']]);

// Display the result
console.log(`${hf.getCellValue({ sheet: sheetId, row: 0, col: 0 })}: ${hf.getCellValue({ sheet: sheetId, row: 0, col: 1 })}`);
