Basic Usage

Installation

dotnet add package ExcelizeCs --version 0.0.1

Create spreadsheet

Here is a minimal example usage that will create spreadsheet file.

using ExcelizeCs;

class Program
{
    static void Main()
    {
        var f = Excelize.NewFile();
        try
        {
            // Create a new sheet.
            var index = f.NewSheet("Sheet2");
            // Set value of a cell.
            f.SetCellValue("Sheet2", "A1", "Hello world.");
            f.SetCellValue("Sheet1", "B2", 100);
            // Set active sheet of the workbook.
            f.SetActiveSheet(index);
            // Save spreadsheet by the given path.
            f.SaveAs("Book1.xlsx");
        }
        catch (RuntimeError err)
        {
            Console.WriteLine(err.Message);
        }
        finally
        {
            var err = f.Close();
            if (!string.IsNullOrEmpty(err))
                Console.WriteLine(err);
        }
    }
}

Reading spreadsheet

The following constitutes the bare to read a spreadsheet document.

using ExcelizeCs;

class Program
{
    static void Main()
    {
        ExcelizeCs.File? f;
        try
        {
            f = Excelize.OpenFile("Book1.xlsx");
        }
        catch (RuntimeError err)
        {
            Console.WriteLine(err.Message);
            return;
        }
        try
        {
            // Get value from cell by given worksheet name and cell reference.
            var cell = f.GetCellValue("Sheet1", "B2");
            Console.WriteLine(cell);
            // Get all the rows in the Sheet1.
            var rows = f.GetRows("Sheet1");
            foreach (var row in rows)
            {
                foreach (var c in row)
                {
                    Console.Write($"{c}\t");
                }
                Console.WriteLine();
            }
        }
        catch (RuntimeError err)
        {
            Console.WriteLine(err.Message);
        }
        finally
        {
            // Close the spreadsheet.
            var err = f.Close();
            if (!string.IsNullOrEmpty(err))
                Console.WriteLine(err);
        }
    }
