Implementing Document Generation in ASP.NET Core

Let's look at how to implement basic asp.net core document generation with Open XML SDK:

public byte[] GenerateWordDocument(ReportData data)
{
    // Create a memory stream to store the document
    using (MemoryStream ms = new MemoryStream())
    {
        // Create a new Word document
        using (WordprocessingDocument doc = WordprocessingDocument.Create(ms, WordprocessingDocumentType.Document))
        {
            // Add a main document part
            MainDocumentPart mainPart = doc.AddMainDocumentPart();
            mainPart.Document = new Document();
            Body body = mainPart.Document.AppendChild(new Body());
            
            // Add content to the document
            Paragraph para = body.AppendChild(new Paragraph());
            Run run = para.AppendChild(new Run());
            run.AppendChild(new Text($"Report for {data.ClientName}"));
            
            // Add more content as needed
            
            // Save the document
            mainPart.Document.Save();
        }
        
        return ms.ToArray();
    }
}

This is a simple example, but you can extend it to create complex documents with tables, charts, and formatted text.

Automating Word Excel in ASP.NET with Open XML SDK

One of the most common use cases is automating the creation of Word and Excel files. Here's how you can implement a basic Excel report generator:

public byte[] GenerateExcelReport(List<SalesData> salesData)
{
    using (MemoryStream ms = new MemoryStream())
    {
        using (SpreadsheetDocument document = SpreadsheetDocument.Create(ms, SpreadsheetDocumentType.Workbook))
        {
            WorkbookPart workbookPart = document.AddWorkbookPart();
            workbookPart.Workbook = new Workbook();
            
            WorksheetPart worksheetPart = workbookPart.AddNewPart<WorksheetPart>();
            worksheetPart.Worksheet = new Worksheet();
            
            Sheets sheets = document.WorkbookPart.Workbook.AppendChild(new Sheets());
            Sheet sheet = new Sheet() { Id = document.WorkbookPart.GetIdOfPart(worksheetPart), SheetId = 1, Name = "Sales Report" };
            sheets.Append(sheet);
            
            SheetData sheetData = worksheetPart.Worksheet.AppendChild(new SheetData());
            
            // Add header row
            Row headerRow = new Row();
            headerRow.Append(
                CreateCell("Date"),
                CreateCell("Product"),
                CreateCell("Quantity"),
                CreateCell("Revenue")
            );
            sheetData.Append(headerRow);
            
            // Add data rows
            foreach (var sale in salesData)
            {
                Row dataRow = new Row();
                dataRow.Append(
                    CreateCell(sale.Date.ToString("yyyy-MM-dd")),
                    CreateCell(sale.ProductName),
                    CreateCell(sale.Quantity.ToString()),
                    CreateCell(sale.Revenue.ToString("C"))
                );
                sheetData.Append(dataRow);
            }
            
            workbookPart.Workbook.Save();
        }
        
        return ms.ToArray();
    }
}

private Cell CreateCell(string text)
{
    Cell cell = new Cell();
    cell.DataType = CellValues.String;
    cell.CellValue = new CellValue(text);
    return cell;
}

This approach allows you to create dynamic Excel reports without relying on COM automation, which isn't recommended in server environments.
