    Edit Word Documents in Node.js and Java

    How to edit a Word document?

    GroupDocs.Editor for Node.js and Java supports editing WordProcessing formats such as DOC, DOCX, DOT, DOCM, DOTX, ODT, and RTF. It allows two processing modes:

    • float (default)
    • paged (also known as paginal)

    In float mode, the document appears as a single page when loaded into the WYSIWYG editor. In paged mode, the document is displayed with its original page breaks, similar to Microsoft Word.

    Loading WordProcessing documents

    Start by loading the document into the Editor class. Here’s an example of loading a password-protected DOCX file:

    const groupdocs = require('groupdocs-editor');
const Editor = groupdocs.Editor;
const WordProcessingLoadOptions = groupdocs.options.WordProcessingLoadOptions;

// Load options for a password-protected document
const loadOptions = new WordProcessingLoadOptions();
loadOptions.password = "some_password_to_open_document";

// Load the document into the Editor
const inputPath = "C://input_path/document.docx";
const editor = new Editor(inputPath, loadOptions);

## How to edit a Word document?

GroupDocs.Editor for Node.js supports editing WordProcessing formats such as DOC, DOCX, DOT, DOCM, DOTX, ODT, and RTF. It allows two processing modes:

- **float** (default)
- **paged** (also known as **paginal**)

In float mode, the document appears as a single page when loaded into the WYSIWYG editor. In paged mode, the document is displayed with its original page breaks, similar to Microsoft Word.

### Loading WordProcessing documents

Start by loading the document into the `Editor` class. Here’s an example of loading a password-protected DOCX file:

```javascript
const groupdocs = require('groupdocs-editor');
const Editor = groupdocs.Editor;
const WordProcessingLoadOptions = groupdocs.options.WordProcessingLoadOptions;

// Load options for a password-protected document
const loadOptions = new WordProcessingLoadOptions();
loadOptions.password = "some_password_to_open_document";

// Load the document into the Editor
const inputPath = "C://input_path/document.docx";
const editor = new Editor(inputPath, loadOptions);

    If the document is unprotected, the password will be ignored. If the document is protected but no password is provided, an error will be thrown during editing.

    Editing WordProcessing documents

    Once the document is loaded, you can edit it by creating WordProcessingEditOptions:

    const WordProcessingEditOptions = groupdocs.options.WordProcessingEditOptions;

let editOptions = new WordProcessingEditOptions();
editOptions.fontExtraction = groupdocs.options.FontExtractionOptions.ExtractEmbeddedWithoutSystem;
editOptions.enableLanguageInformation = true;
editOptions.enablePagination = true;

    Explanation:

    • fontExtraction: Extracts fonts used in the document.
    • enableLanguageInformation: Enables language information extraction for spell-checking.
    • enablePagination: Switches from the default float mode to paged mode.

    Next, edit the document using the prepared options:

    let editableDocument = editor.edit(editOptions);

    To extract the HTML markup and resources separately:

    let originalContent = editableDocument.getContent();
let allResources = editableDocument.getAllResources();

    Modifying document content

    After editing the document in the WYSIWYG-editor on the client side, pass the modified content back to the server:

    let editedContent = originalContent.replace("document", "edited document");
let updatedDocument = groupdocs.EditableDocument.fromMarkup(editedContent, allResources);

    Saving the Word document after editing

    To save the edited document, you first need to create WordProcessingSaveOptions:

    const WordProcessingSaveOptions = groupdocs.options.WordProcessingSaveOptions;

let saveOptions = new WordProcessingSaveOptions(groupdocs.formats.WordProcessingFormats.Docm);
saveOptions.password = "password";
saveOptions.enablePagination = true;
saveOptions.locale = "en-US";
saveOptions.optimizeMemoryUsage = true;
saveOptions.protection = new groupdocs.options.WordProcessingProtection(
    groupdocs.options.WordProcessingProtectionType.ReadOnly, 
    "write_password"
);

    Explanation:

    1. WordProcessingFormats.Docm: Sets the format to DOCM.
    2. password: Encrypts the document with a password.
    3. enablePagination: Preserves pagination in the saved document.
    4. locale: Sets the locale.
    5. optimizeMemoryUsage: Optimizes memory for large documents.
    6. protection: Adds write protection to the document.

    Finally, save the document:

    let outputPath = "C://output_path/edited_document.docm";
editor.save(updatedDocument, outputPath, saveOptions);
