Load Document Without Options

This basic feature allows you to quickly access a document from a file path without additional configurations.

Overview

  • Purpose: Quick loading for small or simple documents where no special handling is required.
  • Use Case: Ideal for straightforward document access.
import com.groupdocs.editor.Editor;

String inputPath = "YOUR_DOCUMENT_DIRECTORY/sample.docx"; // Replace with your document path
Editor editor1 = new Editor(inputPath);
editor1.dispose();

Load Document With Word Processing Options

Enhance security and control by loading documents with specific options, such as setting a password.

Overview

  • Purpose: Adds an extra layer of security for sensitive documents.
  • Use Case: Useful when handling confidential files requiring authentication.
import com.groupdocs.editor.Editor;
import com.groupdocs.editor.options.WordProcessingLoadOptions;

String inputPath = "YOUR_DOCUMENT_DIRECTORY/sample.docx"; // Replace with your document path
WordProcessingLoadOptions wordLoadOptions = new WordProcessingLoadOptions();
wordLoadOptions.setPassword("some password"); // Set the document password if needed

Editor editor2 = new Editor(inputPath, wordLoadOptions);
editor2.dispose();

Load Document From InputStream Without Options

For scenarios where documents are not stored on disk, load them directly from an InputStream.

Overview

  • Purpose: Facilitates handling of dynamic data sources.
  • Use Case: Great for web applications processing uploaded files.
import com.groupdocs.editor.Editor;
import java.io.FileInputStream;
import java.io.InputStream;

InputStream inputStream = new FileInputStream("YOUR_DOCUMENT_DIRECTORY/sample.xlsx"); // Replace with your file path

Editor editor3 = new Editor(inputStream);
editor3.dispose();

Load Document From InputStream With Spreadsheet Options

Optimize memory usage when dealing with large spreadsheet files by using specific load options.

Overview

  • Purpose: Reduces the memory footprint for handling large documents.
  • Use Case: Essential for efficiently processing big data files.
import com.groupdocs.editor.Editor;
import com.groupdocs.editor.options.SpreadsheetLoadOptions;
import java.io.FileInputStream;
import java.io.InputStream;

InputStream inputStream2 = new FileInputStream("YOUR_DOCUMENT_DIRECTORY/sample.xlsx"); // Replace with your file path

SpreadsheetLoadOptions sheetLoadOptions = new SpreadsheetLoadOptions();
sheetLoadOptions.setOptimizeMemoryUsage(true); // Optimize memory usage for large documents

Editor editor4 = new Editor(inputStream2, sheetLoadOptions);
editor4.dispose();
