Quickstart

Create a Workbook

Create a new workbook, write values to cells, and save to XLSX:

import { Workbook } from "@aspose/cells";

const workbook = new Workbook();
const worksheet = workbook.worksheets[0]!;

worksheet.putValue("A1", "Product");
worksheet.putValue("B1", "Revenue");
worksheet.putValue("A2", "Widget");
worksheet.putValue("B2", 42000);
worksheet.putValue("A3", "Gadget");
worksheet.putValue("B3", 31500);

await workbook.save("report.xlsx");

Load an Existing Workbook

Open an existing XLSX file and read cell values:

import { Workbook } from "@aspose/cells";

const workbook = await Workbook.load("report.xlsx");
const worksheet = workbook.worksheets[0]!;

const product = worksheet.getCell(0, 0)?.value;
const revenue = worksheet.getCell(0, 1)?.value;
console.log(`${product}: ${revenue}`);

Apply Styling

Create a Style object and apply font settings to a cell:

import { Workbook, Style } from "@aspose/cells";

const workbook = new Workbook();
const worksheet = workbook.worksheets[0]!;

const style = new Style();
style.setFontName("Arial");
style.setFontSize(14);
style.setBold(true);
style.setFontColor("FF0000");

const cell = worksheet.getCell2("A1");
cell.putValue("Styled Text");
cell.setStyle(style);

await workbook.save("styled.xlsx");

Export to Multiple Formats

Save workbooks to CSV, JSON, Markdown, and HTML:

import { Workbook } from "@aspose/cells";

const workbook = new Workbook();
const worksheet = workbook.worksheets[0]!;
worksheet.putValue("A1", "Name");
worksheet.putValue("B1", "Age");
worksheet.putValue("A2", "Alice");
worksheet.putValue("B2", 25);

await workbook.save("data.xlsx");
await workbook.save("data.csv");
await workbook.save("data.json");
await workbook.save("data.md");
