Convert a Markdown File to a Word Document with Java
Spire.Doc for Java provides a simple way to convert Markdown format to Word and PDF document formats by using the Document.loadFromFile(String: fileName, FileFormat.Markdown) method to load the Markdown file and the Document.saveToFile(String: fileName, FileFormat: fileFormat) method to save the file as a Word or PDF document.
It should be noted that since images are stored as links in Markdown files, they need to be further processed after conversion if they are to be retained.
The detailed steps for converting a Markdown file to a Word document are as follows:
- Create an instance of Document class.
- Load a Markdown file using Document.loadFromFile(String: fileName, FileFormat.Markdown) method.
- Save the Markdown file as Word document using Document.saveToFile(String: fileName, FileFormat.Docx) method.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
public class MarkdownToWord {
public static void main(String[] args) {
// Create an instance of Document
Document doc = new Document();
// Load a Markdown file
doc.loadFromFile("Sample.md", FileFormat.Markdown);
// Save the Markdown file as Word document
doc.saveToFile("output/MarkdownToWord.docx", FileFormat.Docx);
doc.dispose();
}
}
Convert a Markdown File to a PDF Document with Java
By using the FileFormat.PDF Enum as the format parameter of the Document.saveToFile() method, the Markdown file can be directly converted to a PDF document.
The detailed steps for converting a Markdown file to a PDF document are as follows:
- Create an instance of Document class.
- Load a Markdown file using Document.loadFromFile(String: fileName, FileFormat.Markdown) method.
- Save the Markdown file as PDF document using Document.saveToFile(String: fileName, FileFormat.PDF) method.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
public class MarkdownToPDF {
public static void main(String[] args) {
// Create an instance of the Document class
Document doc = new Document();
// Load a Markdown file
doc.loadFromFile("Sample.md");
// Save the Markdown file as a PDF file
doc.saveToFile("output/MarkdownToPDF.pdf", FileFormat.PDF);
doc.dispose();
}
}
Customizing Page Settings of the Result Document
Spire.Doc for Java also provides methods under PageSetup class to do page setup before the conversion, allowing control over page settings such as page margins and page size of the resulting document.
The following are the steps to customize the page settings of the resulting document:
- Create an instance of Document class.
- Load a Markdown file using Document.loadFromFile(String: fileName, FileFormat.Markdown) method.
- Get the first section using Document.getSections().get() method.
- Set the page size, page orientation, and page margins using methods under PageSetup class.
- Save the Markdown file as PDF document using Document.saveToFile(String: fileName, FileFormat.PDF) method.
- Java
import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.PageSetup;
import com.spire.doc.Section;
import com.spire.doc.documents.MarginsF;
import com.spire.doc.documents.PageOrientation;
import com.spire.doc.documents.PageSize;
public class PageSettingMarkdown {
public static void main(String[] args) {
// Create an instance of the Document class
Document doc = new Document();
// Load a Markdown file
doc.loadFromFile("Sample.md");
// Get the first section
Section section = doc.getSections().get(0);
// Set the page size, orientation, and margins
PageSetup pageSetup = section.getPageSetup();
pageSetup.setPageSize(PageSize.Letter);
pageSetup.setOrientation(PageOrientation.Landscape);
pageSetup.setMargins(new MarginsF(100, 100, 100, 100));
// Save the Markdown file as a PDF file
doc.saveToFile("output/MarkdownToPDF.pdf", FileFormat.PDF);
doc.dispose();
}

Java: Convert Word to Excel
Word and Excel are different from each other in terms of their uses and functioning. Word is used primarily for text documents such as essays, emails, letters, books, resumes, or academic papers where text formatting is essential. Excel is used to save data, make tables and charts and make complex calculations.
It is not recommended to convert a complex Word file to an Excel spreadsheet, because Excel can hardly render contents in the same way as Word. However, if your Word document is mainly composed of tables and you want to analyze the table data in Excel, you can use Spire.Office for Java to convert Word to Excel while maintaining good readability.
Install Spire.Office for Java
First of all, you're required to add the Spire.Office.jar file as a dependency in your Java program. The JAR file can be downloaded from this link. If you use Maven, you can easily import the JAR file in your application by adding the following code to your project's pom.xml file.

Convert Word to Excel in Java
This scenario actually uses two libraries in the Spire.Office package. They're Spire.Doc for Java and Spire.XLS for Java. The former is used to read and extract content from a Word document, and the latter is used to create an Excel document and write data in the specific cells. To make this code example easy to understand, we created the following three custom methods that preform specific functions.
- exportTableInExcel() - Export data from a Word table to specified Excel cells.
- copyContentInTable() - Copy content from a table cell in Word to an Excel cell.
- copyTextAndStyle() - Copy text with formatting from a Word paragraph to an Excel cell.
The following steps demonstrate how to export data from a Word document to a worksheet using Spire.Office for Java.
- Create a Document object to load a Word file.
- Create a Workbook object and add a worksheet named "WordToExcel" to it.
- Traverse though all the sections in the Word document, traverse through all the document objects under a certain section, and then determine if a document object is a paragraph or a table.
- If the document object is a paragraph, write the paragraph in a specified cell in Excel using coypTextAndStyle() method.
- If the document object is a table, export the table data from Word to Excel cells using exportTableInExcel() method.
- Auto fit the row height and column width in Excel so that the data within a cell will not exceed the bound of the cell.
- Save the workbook to an Excel file using Workbook.saveToFile() method.
