5 Steps to Create and Style Excel Files with IronXL

WorkBook workBook = WorkBook.Create();
WorkSheet workSheet = workBook.CreateWorkSheet("new_sheet");
workSheet["A1"].Value = "Hello World";
workSheet["A1"].Style.WrapText = true;
workBook.SaveAs("sample.xlsx");

The WorkBook object serves as the foundation of any Excel file. By initializing a new workbook, developers gain access to a blank Excel document, ready to be populated with data and formatted as needed.

Every Excel workbook requires at least one worksheet. The next step demonstrates how to create a new sheet within the workbook and assign it a custom name. Worksheets act as the primary structure for organizing data in rows and columns.

The snippet demonstrates how to add content by assigning the value "Hello World" to a specific cell, A1. This shows how easy it is to populate data into an Excel sheet programmatically, enabling developers to automate tasks like report generation and data export.

Additionally, the snippet applies styling to the cell by enabling the WrapText property. This ensures that lengthy content in the cell is displayed neatly across multiple lines, improving readability and preventing text from being cut off. Such styling options empower developers to create visually appealing and professional spreadsheets.

Lastly, the workbook is saved as an .xlsx file, ensuring all changes are preserved. This file can be opened in any Excel-compatible application, offering broad compatibility.
