Add footnotes to Word documents in Java

Footnote A type of annotation that describes the content of a word or sentence. Often placed at the bottom of a page. Due to the footnotes, the user can learn some complex words more clearly and the integrity can be preserved. Therefore, this specification uses Spire.Doc to add footnotes to Word documents for Java applications. The method will be described.

1. Add a footnote after the entire paragraph.
2. Search for the specified text and add a footnote after the search text. Add a footnote to the first paragraph of the word document:

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
import java.awt.*;


public class WordFootnote {
    public static void main(String[] args) throws Exception {
        //Load sample document
        Document doc = new Document();
        doc.loadFromFile("Sample.docx", FileFormat.Docx_2010);

        //Get the first stage of the first selection.
        Paragraph para = doc.getSections().get(0).getParagraphs().get(0);

        //Add a footnote after the first paragraph
        Footnote footnote = para.appendFootnote(FootnoteType.Footnote);

        //Add footnote content and format the font
        TextRange text = footnote.getTextBody().addParagraph().appendText("Demo of Spire.Doc");
        text.getCharacterFormat().setFontName("Arial Black");
        text.getCharacterFormat().setFontSize(10);
        text.getCharacterFormat().setTextColor(new Color(255, 140, 0));
        footnote.getMarkerCharacterFormat().setFontName("Calibri");
        footnote.getMarkerCharacterFormat().setFontSize(12);
        footnote.getMarkerCharacterFormat().setBold(true);
        footnote.getMarkerCharacterFormat().setTextColor(new Color(0, 0, 139));

        //Save document
        doc.saveToFile("output/Addfootnote.docx", FileFormat.Docx_2010);

        }
    }

Search for the specified text Spire.Doc and add a footnote:

import com.spire.doc.*;
import com.spire.doc.documents.*;
import com.spire.doc.fields.*;
import java.awt.*;


public class WordFootnotes {
    public static void main(String[] args) throws Exception {
        //Load sample document
        Document doc = new Document();
        doc.loadFromFile("Sample.docx", FileFormat.Docx_2010);
        
        //Search text Spire.Doc
        TextSelection[] selections = doc.findAllString("Spire.Doc", false, true);
        for (TextSelection selection : selections) {
            TextRange range = selection.getAsOneRange();
            Paragraph para = range.getOwnerParagraph();

            //Adds a footnote after the specified text
            Footnote footnote = para.appendFootnote(FootnoteType.Footnote);
            int index = para.getChildObjects().indexOf(range);

            para.getChildObjects().insert(index + 1, footnote);

            //Add footnote content and format the font
            TextRange text = footnote.getTextBody().addParagraph().appendText("Demo of Spire.Doc");
            text.getCharacterFormat().setFontName("Arial Black");
            text.getCharacterFormat().setFontSize(10);
            text.getCharacterFormat().setTextColor(new Color(255, 140, 0));
            footnote.getMarkerCharacterFormat().setFontName("Calibri");
            footnote.getMarkerCharacterFormat().setFontSize(12);
            footnote.getMarkerCharacterFormat().setBold(true);
            footnote.getMarkerCharacterFormat().setTextColor(new Color(0, 0, 139));

            //Save document
            doc.saveToFile("output/Addfootnote.docx", FileFormat.Docx_2010);

        }
    }
