How to Create .NET Core Word in Form Field of JSON and convert to PDF?

Syncfusion; Essential; DocIO is a .NET Word library used to create, read, edit, and convert Word documents programmatically without Microsoft Word or interop dependencies. Using this library, you can create a Word document with form fields from JSON and convert it to PDF using C#.

Steps to create a Word document with form fields from JSON and convert it to PDF:

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

   

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

   

3. Include the following namespaces in the Program.cs file.
   C#

using Syncfusion.DocIO;
using Syncfusion.DocIO.DLS;
using Syncfusion.DocIORenderer;
using Syncfusion.Pdf;

4. Use the following code example to create a Word document with form fields from JSON and convert it to PDF.
   C#

// Read and deserialize JSON data.
var jsonString = File.ReadAllText(Path.GetFullPath("Data/ReportData.json"));
var data = JsonConvert.DeserializeObject<Root>(jsonString);

using (WordDocument document = new WordDocument())
{
    //// Get the text from JSON and replace in Word document
    // Adds new section to the document
    IWSection section = document.AddSection();
    // Adds new paragraph to the section
    WParagraph paragraph = section.AddParagraph().AppendText("General Information") as WParagraph;
    section.AddParagraph();

    AddTextFormField(section, "EmployeeID", data.Reports[0].EmployeeID);
    AddTextFormField(section, "Name", data.Reports[0].Name);
    AddTextFormField(section, "PhoneNumber", data.Reports[0].PhoneNumber);
    AddTextFormField(section, "Location", data.Reports[0].Location);

    // Creates an instance of DocIORenderer.
    using (DocIORenderer renderer = new DocIORenderer())
    {
        // Converts Word document into PDF document.
        using (PdfDocument pdfDocument = renderer.ConvertToPDF(document))
        {
            // Saves the PDF file to file system.    
            using (FileStream outputStream = new FileStream(Path.GetFullPath(@"Output/Result.pdf"), FileMode.Create, FileAccess.ReadWrite, FileShare.ReadWrite))
            {
                pdfDocument.Save(outputStream);
            }
        }
    }
}

5. Use the following code example to add the text form field in the Word document.
   C#

private static void AddTextFormField(IWSection section, string label, string value)
{
    WParagraph paragraph = section.AddParagraph() as WParagraph;
    IWTextRange text = paragraph.AppendText(label + ": ");
    text.CharacterFormat.Bold = true;

    WTextFormField textField = paragraph.AppendTextFormField(null);
    textField.Type = TextFormFieldType.RegularText;
    textField.CharacterFormat.FontName = "Calibri";
    textField.Text = value;
    textField.CalculateOnExit = true;

    section.AddParagraph();
} 

6. Use the following code example for report data with employee details and the Root object for deserializing JSON data.
   C#

/// <summary>
/// Represents report data with employee details.
/// </summary>
public class Reports
{
    [JsonProperty("EmployeeID")] public string EmployeeID { get; set; }
    [JsonProperty("Name")] public string Name { get; set; }
    [JsonProperty("PhoneNumber")] public string PhoneNumber { get; set; }
    [JsonProperty("Location")] public string Location { get; set; }

}
/// <summary>
/// Root object for deserializing JSON data.
/// </summary>
public class Root
{
    [JsonProperty("Reports")] public List<Reports> Reports { get; set; }
}
