//Saves the Word document.
document.save("Sample.docx", FormatType.Docx);
//Closes the document.
document.close();

Modify equation using LaTeX

You can modify the text of an equation by replacing the string value in the LaTeX API, which retrieves the LaTeX string representation of the professional equation in the Word document.

The following code snippet shows how to modify the LaTeX equation in a Word document.

JAVA

//Creates a new Word document.
WordDocument document = new WordDocument("Template.docx", FormatType.Automatic);
//Adds one section and one paragraph to the document.
document.ensureMinimal();
		
// Access the first paragraph from the last section of the document.
WParagraph paragraph = (WParagraph)document.getLastSection().getBody().getChildEntities().get(0);
// Retrieve the first math equation in the paragraph, if it exists.
WMath math = (WMath) paragraph.getChildEntities().get(0);
if (math != null)
{
    // Get the LaTeX representation of the math equation.
    String laTeX = math.getMathParagraph().getLaTeX();
    // Replace occurrences of 'x' with 'k' in the LaTeX representation.
    math.getMathParagraph().setLaTeX(laTeX.replace("x", "k"));
}

//Saves the Word document.
document.save("Sample.docx", FormatType.Docx);
//Closes the document.
document.close();
