Adding or removing text boxes in Word is a valuable skill that enhances document layout and visual appeal. Text boxes provide a flexible way to highlight important information, create side notes, or organize content more effectively. They allow for creative formatting options, enabling you to draw attention to specific areas of your document.

In this article, you will learn how to add or move text boxes in a Word document in React using Spire.Doc for JavaScript.

Install Spire.Doc for JavaScript

To get started wtih manipulating text boxes in Word in a React applicaiton, you can either download Spire.Doc for JavaScript from our website or install it via npm with the following command:

Copy

npm i spire.office

The downloaded product package integrates Spire.Doc for JavaScript, Spire.XLS for JavaScript, Spire.PDF for JavaScript, and Spire.Presentation for JavaScript. To use the features of Spire.Doc for JavaScript, you need to copy the corresponding files (spire.doc.js, Spire.Doc.Wasm.zip, spire.common.js, Spire.Common.Wasm.zip, and the _framework folder) to the public folder of your project. To ensure proper text rendering, you can add relevant font files with a custom path. In the following example, the font is added to the path: public\static\font.

Add a Text Box to a Word Document in React

Spire.Doc for JavaScript offers the Paragraph.AppendTextBox() method to seamlessly insert a text box into a specified paragraph. Once inserted, you can customize the text box by adding content and applying formatting using properties like TextBox.Body and TextBox.Format.

The following are the steps to add a text box to a Word document in React:

Load required font and input file into the virtual file system (VFS).
Create a Document object using the new wasmModule.Document() method.
Load the Word file using the Document.LoadFromFile() method.
Access the first section and paragraph.
Insert a text box to the paragraph using the Paragraph.AppendTextBox() method.
Add a paragraph to the text box and append text to it through the TextBox.Body property.
Customize the appearance of the text box through the TextBox.Format property.
Save the document and trigger a download.

      let paragraph = section.Paragraphs.get_Item(0)

      // Insert a textbox and set its wrapping style
      let textBox = paragraph.AppendTextBox(150, 100);
      textBox.Format.TextWrappingStyle = wasmModule.TextWrappingStyle.Square;

      // Set the position of the textbox
      textBox.Format.HorizontalPosition = 0;
      textBox.Format.VerticalPosition = 50;

      // Set the line style and fill color
      textBox.Format.LineColor = wasmModule.Color.get_DarkBlue();
      textBox.Format.LineStyle = wasmModule.TextBoxLineStyle.Simple;

      textRange.CharacterFormat.FontName = "Arial";
      textRange.CharacterFormat.FontSize = 15;
      textRange.CharacterFormat.TextColor = wasmModule.Color.get_Blue();

      // Set the horizontal alignment of the paragraph
      para.Format.HorizontalAlignment = wasmModule.HorizontalAlignment.Center;

      // Save the document to the specified path

Run the code to launch the React app at localhost:3000. Click "Generate", and a "Save As" window will appear, prompting you to save the output file in your chosen folder.

Remove a Text Box from a Word Document in React

Spire.Doc for JavaScript includes the Document.TextBoxes.RemoveAt() method, which allows you to delete a specific text box by its index. If you need to remove all text boxes from a Word document, you can use the Document.TextBoxes.Clear() method for a quick and efficient solution.

The following are the steps to remove a text box from a Word document in React:

Load the input file into the virtual file system (VFS).
Create a Document object using the new wasmModule.Document() method.
Load the Word file using the Document.LoadFromFile() method.
Remove a specific text box using the Document.TextBoxes.RemoveAt() method.
Save the document and trigger a download.

      // Load the Word document
