GroupDocs Editor – Edit DOCX In‑Memory Showcase

Overview

This showcase project demonstrates how to edit a DOCX document completely in memory using GroupDocs.Editor for Java 26.1. The example loads a DOCX file, replaces a piece of text (Hello → Hi) and saves the edited document without ever persisting intermediate data to disk.

Project Structure

project-root/
├─ pom.xml
├─ src/
│  └─ main/java/com/groupdocs/editor/examples/EditDocxInMemoryExample.java
├─ resources/
│  ├─ input/
│  │   └─ sample.docx   (replace with your own DOCX) 
│  └─ output/           (generated files will appear here)
└─ GroupDocs.Editor.lic (optional – place your license file here)

Prerequisites

• Java 8 (or higher)
• Maven 3.6+
• Internet access for Maven to download the GroupDocs repository

License

GroupDocs library requires a license. You can obtain a free 30‑day temporary license:

• Visit: https://purchase.groupdocs.com/temporary-license/
• Download the license file (e.g., GroupDocs.Editor.lic).
• Place the license file in the project root (same level as pom.xml).

Without a license the library runs in evaluation mode, adding watermarks and some usage limitations.

Setup & Execution

1. Clone / download the project

   git clone https://github.com/your-repo/groupdocs-editor-java-edit-docx-in-memory.git
   cd groupdocs-editor-java-edit-docx-in-memory

2. Add your license file (optional but recommended) – copy GroupDocs.Editor.lic into the project root.
3. Place a DOCX file you want to edit into resources/input/ and rename it to sample.docx (or replace the existing placeholder).
4. Build the project

   mvn clean compile

5. Run the example

   mvn exec:java

What the Example Does

• Loads resources/input/sample.docx via an InputStream.
• Creates a Editor instance with default LoadOptions.
• Performs an in‑memory text replacement (Hello → Hi).
• Saves the edited document to resources/output/edited_sample.docx using an OutputStream.
• All operations stay in memory; only the final file is written to disk.

Customising the Demo

• Change the text to replace – modify the TextReplacer parameters in EditDocxInMemoryExample.java.
• Add more complex edits – explore other editing elements offered by GroupDocs.Editor such as ParagraphReplacer, ImageReplacer, etc.
• Work with other formats – GroupDocs.Editor supports DOC, DOCX, ODT, RTF, and more. Adjust the input file accordingly.

Notes

• The sample sample.docx included in the repository is only a placeholder. Replace it with a real DOCX to see the actual editing effect.
• Ensure the resources/output/ directory is writable; the code will create it automatically if missing.
• This project is intended purely as a showcase. For production use, add robust error handling, logging, and resource management as required.
