Create Excel (XLSX) or PDF file on Linux or macOS

GemBox.Spreadsheet provides support for .NET Standard 2.0, a cross-platform specification of .NET APIs, which is why it can be used on non-Windows platforms like Linux and macOS.

The following example shows how you can create an Excel workbook and a PDF file using GemBox.Spreadsheet on Linux (Ubuntu).

Prerequisites

After installing the requirements listed above you can follow these steps that show how you can easily use a Visual Studio Code (VS Code) to create a simple Console project and a C# code that generates a XLSX file.

1. Open a project folder

  • Open VS Code.
  • Click "Open Folder" on the EXPLORER panel.
  • Select the folder you want your console project to be in, for instance a folder named GemBoxExample.

2. Create a new console project

  • Open Integrated Terminal in VS Code by clicking "View" > "Terminal" or using CTRL + ` shortcut.
  • In the terminal window execute following command: dotnet new console
  • This command will create a code file (Program.cs) and a project file (GemBoxExample.csproj) inside the opened folder.

3. Edit project files

  • Add a reference to GemBox.Spreadsheet and its dependencies in GemBoxExample.csproj file:
    <ItemGroup>
      <PackageReference Include="GemBox.Spreadsheet" Version="*" />
    
      <PackageReference Include="System.Drawing.Common" Version="*" />
    
      <!-- Required if PDF file is digitally signed. -->
      <PackageReference Include="System.Security.Cryptography.Pkcs" Version="*" />
    </ItemGroup>
    Note that System.Drawing.Common assembly has a reference to a native libgdiplus library which must be installed on a non-Windows system.
    To install it on Linux use the following command: sudo apt-get install libgdiplus
    To install it on macOS use Homebrew with the following command: brew install mono-libgdiplus
  • Edit C# code in Program.cs file:
    using GemBox.Spreadsheet;
    
    class Program
    {
        static void Main()
        {
            // If using Professional version, put your serial key below.
            SpreadsheetInfo.SetLicense("FREE-LIMITED-KEY");
    
            var workbook = new ExcelFile();
            var worksheet = workbook.Worksheets.Add("Hello World");
    
            worksheet.Cells[0, 0].Value = "English:";
            worksheet.Cells[0, 1].Value = "Hello";
    
            worksheet.Cells[1, 0].Value = "Russian:";
            // Using UNICODE string.
            worksheet.Cells[1, 1].Value = new string(new char[] { '\u0417', '\u0434', '\u0440', '\u0430', '\u0432', '\u0441', '\u0442', '\u0432', '\u0443', '\u0439', '\u0442', '\u0435' });
    
            worksheet.Cells[2, 0].Value = "Chinese:";
            // Using UNICODE string.
            worksheet.Cells[2, 1].Value = new string(new char[] { '\u4f60', '\u597d' });
    
            worksheet.Cells[4, 0].Value = "In order to see Russian and Chinese characters you need to have appropriate fonts on your PC.";
            worksheet.Cells.GetSubrangeAbsolute(4, 0, 4, 7).Merged = true;
    
            workbook.Save("Output.xlsx");
            workbook.Save("Output.pdf");
        }
    }

4. Run the console project

  • In the terminal window execute following command: dotnet run
  • This command will run your Console application and create an Excel workbook (Output.xlsx) and a PDF file (Output.pdf) that you open in any Excel and PDF applications.
