The following are the main steps to insert a superscript or subscript into a Word document using Spire.Doc for Java:
- Create a Document instance.
- Load a Word document using Document.loadFromFile() method.
- Get the specific section using Document.getSections().get(sectionIndex) method.
- Add a paragraph to the section using Section.addParagraph() method.
- Add normal text to the paragraph using Paragraph.appendText() method.
- Add superscript or subscript text to the paragraph using Paragraph.appendText() method.
- Apply superscript or subscript formatting to the superscript or subscript text through TextRange.getCharacterFormat().setSubSuperScript() method.
- Save the result document using Document.saveToFile() method.

//Add a paragraph to the section
Paragraph paragraph = section.addParagraph();
//Add normal text to the paragraph
paragraph.appendText("E = mc");
//Add superscript text to the paragraph
TextRange superscriptText = paragraph.appendText("2");
//Apply superscript formatting to the superscript text
superscriptText.getCharacterFormat().setSubSuperScript(SubSuperScript.Super_Script);
//Start a new line
paragraph.appendBreak(BreakType.Line_Break);
//Add normal text to the paragraph
paragraph.appendText("H");
//Add subscript text to the paragraph
TextRange subscriptText = paragraph.appendText("2");
//Apply subscript formatting to the subscript text
subscriptText.getCharacterFormat().setSubSuperScript(SubSuperScript.Sub_Script);
//Add normal text to the paragraph
paragraph.appendText("O");
//Set font size for the text in the paragraph
for(Object item : paragraph.getItems())
{
if (item instanceof TextRange)
{
TextRange textRange = (TextRange)item ;
textRange.getCharacterFormat().setFontSize(36f);
}
}
//Save the result document
document.saveToFile("InsertSuperscriptAndSubscript.docx", FileFormat.Docx_2013);
}
}
