Welcome to the PicoXLSX wiki!
PicoXLSX is a small .NET library to create Microsoft Excel files (XLSX for Office 2007 or newer) in an easy and native way. This means:
- No dependencies (*
- No need for an installation of Microsoft Office
- No need for Office interop libraries
- No need for 3rd party libraries
- No need for an installation of the Microsoft Open Office XML SDK (OOXML)
See the Change Log for recent updates.
PicoXLSX was created with .NET version 4.5. Newer versions like 4.6.1 are working and tested. Older versions like 3.5 and 4.0 may also work with minor or no changes. However, this was not tested yet.
*) The only requirement to compile the library besides .NET is the assembly WindowsBase. This assembly is a standard component in all Microsoft Windows systems (except Windows RT systems). If your IDE of choice supports referencing assemblies from the Global Assembly Cache (GAC) of Windows, select WindowsBase from there. If you want so select the DLL manually and Microsoft Visual Studio is installed on your system, the DLL can be found most likely under "c:\Program Files\Reference Assemblies\Microsoft\Framework\v3.0\WindowsBase.dll", according to this MSDN Blog entry. Otherwise you find it in the GAC, under "c:\Windows\Microsoft.NET\assembly\GAC_MSIL\WindowsBase".
If you want to compile the documentation project (folder: Documentation; project file: shfbproj), you need also the Sandcastle Help File Builder (SHFB). It is also freely available. But you don't need the documentation project to build the PicoXLSX library.
By package Manager (PM):
Install-Package PicoXLSX
By .NET CLI:
dotnet add package PicoXLSX
Simply place the PicoXLSX DLL into your .NET project and add a reference (in VS or SharpDevelop) to it. Please keep in mind that the .NET version of your solution must match with the runtime version of the PicoXLSX DLL (currently compiled with 4.5).
Place all .CS files from the PicoXLSX source folder into your project. You can place them into a sub-folder if you wish. The files contains definitions for workbooks, worksheets, cells, styles, meta-data, low level methods and exceptions.
Workbook workbook = new Workbook("myWorkbook.xlsx", "Sheet1"); // Create new workbook with a worksheet called Sheet1
workbook.WS.Value("Some Data"); // Add cell A1
workbook.WS.Formula("=A1"); // Add formula to cell B1
workbook.WS.Down(); // Go to row 2
workbook.WS.Value(DateTime.Now, Style.BasicStyles.Bold); // Add formatted value to cell A2
workbook.Save(); // Save the workbook as myWorkbook.xlsx
Workbook workbook = new Workbook("myWorkbook.xlsx", "Sheet1"); // Create new workbook with a worksheet called Sheet1
workbook.CurrentWorksheet.AddNextCell("Some Data"); // Add cell A1
workbook.CurrentWorksheet.AddNextCell(42); // Add cell B1
workbook.CurrentWorksheet.GoToNextRow(); // Go to row 2
workbook.CurrentWorksheet.AddNextCell(DateTime.Now); // Add cell A2
workbook.Save(); // Save the workbook as myWorkbook.xlsx

The Demo project contains several simple use cases. You can find also the full documentation in the Documentation-Folder or as C# documentation in the .CS files.
