How to find and replace a text with chart in Word document?

Syncfusion® DocIO is a .NET Core Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can find and replace text with a chart in a Word document using C#.

Steps to find and replace text with a chart in a Word document

1. Create a new .NET Core console application project.

2. Install the Syncfusion.DocIO.Net.Core NuGet package as a reference to your application from NuGet.org.
   
   

3. Include the following namespaces in the Program.cs file:

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.OfficeChart;

4. Add the following code snippet in the Program.cs file to find text and replace it with a chart in a Word document.

using (FileStream fileStreamPath = new FileStream("Data/Input.docx", FileMode.Open, FileAccess.Read, FileShare.ReadWrite))
{
      // Open an existing Word document.
      using (WordDocument document = new WordDocument(fileStreamPath, FormatType.Docx))
      {
            // Create text body part.
            TextBodyPart bodyPart = new TextBodyPart(document);
            // Create a chart in a paragraph.
            WParagraph paragraph = CreateBarChart(document);  
            // Add the paragraph to the text body part.  
            bodyPart.BodyItems.Add(paragraph);
            // Replace the placeholder text with a new chart.
            document.Replace("[Purchase details]", bodyPart, true, true, true);
            // Create file stream.
            using (FileStream outputFileStream = new FileStream("Data/Result.docx", FileMode.Create, FileAccess.ReadWrite))
            {
                 // Save the Word document to the file stream.
                 document.Save(outputFileStream, FormatType.Docx);
            }
      }
}

5. Add the helper methods below to create a bar chart for the Word document:

// Create a bar chart inside a new paragraph.
private static WParagraph CreateBarChart(WordDocument document)
{
   // Create a new paragraph.
   WParagraph paragraph = new WParagraph(document);
   // Append a new chart.
   WChart barchart = paragraph.AppendChart(400, 300);
   // Set the type as a bar chart.
   barchart.ChartType = OfficeChartType.Bar_Clustered;
   // Add data for the bar chart.
   AddBarChartData(barchart);

   // Set the other parts of the chart.
   barchart.ChartTitle = "Purchase Details";
   barchart.ChartTitleArea.FontName = "Calibri";
   barchart.ChartTitleArea.Size = 14;
   IOfficeChartSerie serie1 = barchart.Series.Add("Sum of Future Expenses");
   serie1.Values = barchart.ChartData[2, 2, 6, 2];
   IOfficeChartSerie serie2 = barchart.Series.Add("Sum of Purchases");
   serie2.Values = barchart.ChartData[2, 3, 6, 3];

   barchart.HasDataTable = true;
   barchart.DataTable.HasBorders = true;
   barchart.DataTable.HasHorzBorder = true;
   barchart.DataTable.HasVertBorder = true;
   barchart.DataTable.ShowSeriesKeys = true;
   barchart.HasLegend = false;

   barchart.PlotArea.Border.LinePattern = OfficeChartLinePattern.Solid;
   barchart.ChartArea.Border.LinePattern = OfficeChartLinePattern.Solid;
   barchart.PrimaryCategoryAxis.CategoryLabels = barchart.ChartData[2, 1, 6, 1];
   barchart.PrimaryCategoryAxis.Font.Size = 12;
   barchart.PrimaryCategoryAxis.MajorTickMark = OfficeTickMark.TickMark_None;
   barchart.PrimaryValueAxis.MajorTickMark = OfficeTickMark.TickMark_None;

   // Return the new paragraph that has the bar chart in it.
   return paragraph;
}
       
// Add the data for the bar chart.
private static void AddBarChartData(WChart chart)
{
    chart.ChartData.SetValue(1, 2, "Sum of Future Expenses");
    chart.ChartData.SetValue(1, 3, "Sum of Purchases");
    chart.ChartData.SetValue(2, 1, "Nancy Davalio");
    chart.ChartData.SetValue(2, 2, 1300);
    chart.ChartData.SetValue(2, 3, 600);
    chart.ChartData.SetValue(3, 1, "Andrew Fuller");
    chart.ChartData.SetValue(3, 2, 680);
    chart.ChartData.SetValue(3, 3, 1000);
    chart.ChartData.SetValue(4, 1, "Janet Leverling");
    chart.ChartData.SetValue(4, 2, 1280);
    chart.ChartData.SetValue(4, 3, 800);
    chart.ChartData.SetValue(5, 1, "Margaret Peacock");
    chart.ChartData.SetValue(5, 2, 2000);
    chart.ChartData.SetValue(5, 3, 400);
    chart.ChartData.SetValue(6, 1, "Steven Buchanan");
    chart.ChartData.SetValue(6, 2, 2660);
    chart.ChartData.SetValue(6, 3, 731);
}
