# Word template generation and processing

Template generation automates document creation — separating content from design, ensuring consistency, scaling efficiently, reducing errors, and enabling dynamic content based on data.

## How Nutrient helps you achieve this

Nutrient.NET SDK handles template processing. With the SDK, you don’t need to worry about:

- Parsing Word document internals

- Managing XML structures

- Handling style preservation

- Complex placeholder replacement logic

Instead, Nutrient provides an API that handles all the complexity behind the scenes, letting you focus on your business logic.

## Complete implementation

Below is a complete working example that demonstrates Nutrient’s template processing. Start with the SDK imports:

```csharp

using Nutrient;

```

Open the Word template file with a [using declaration](https://learn.microsoft.com/dotnet/csharp/language-reference/statements/using), which disposes the document when you're done, preventing resource leaks:

```csharp

try
{
    using Document document = Document.Open("input_template.docx");

```

Here, you create a `WordEditor` instance that will enable you to manipulate the document. This editor provides all the methods needed for template processing:

```csharp

    using WordEditor editor = WordEditor.Edit(document);

```

This block reads the JSON data model. The dedicated `IOException` catch block below handles file reading errors gracefully:

```csharp

    string model = File.ReadAllText("input_template_model.json");

```

This single line is where the processing occurs. It takes the JSON model and applies it to the template, replacing all placeholders with actual data while preserving all formatting:

```csharp

    editor.ApplyTemplateModel(model);

```

This saves the processed document with all template replacements completed to a new file:

```csharp

    editor.SaveWithModelAs("output.docx");
    Console.WriteLine("Successfully generated document from template");
}
catch (IOException)
{
    Console.Error.WriteLine("Failed to read template model file");
    Environment.Exit(1);
}
catch (NutrientException e)
{
    Console.Error.WriteLine($"Error: {e.Message}");
    Environment.Exit(1);
}

```

## Conclusion

The template processing logic consists of four steps:

1. Open the document.

2. Create an editor.

3. Apply the template model.

4. Save the result.

Nutrient handles complex document processing so you don’t need to understand Word’s internal structure, XML manipulation, or style management.

## Error handling

Nutrient.NET SDK handles errors with exception handling. The methods presented in this guide throw a `NutrientException` if a failure occurs. The `using` statements release the editor and document even when a step fails.
