Template-Based Document Generation via C++

The core philosophy of DocxFactory revolves around simplicity. Instead of programmatically constructing documents element by element, you create a template in Microsoft Word—a regular DOCX file with placeholders—and merge your data into it. This approach offers several advantages, such as faster development, WYSIWYG editing, faster development, and so on. Here is a useful example that demonstrates, how to generate new World documents from a temple using C++ library.

#include "DocxFactory/DocxMerger/DocxMerger.h"
#include "DocxFactory/DocxMerger/DocxMergerItem.h"

// Create a new document from template
DocxFactory::DocxMerger docxMerger;
DocxFactory::DocxMergerItem* item = docxMerger.load("template.docx");

// Set field values
item->setFieldValue("customer.name", "John Smith");
item->setFieldValue("invoice.date", "2024-01-15");
item->setFieldValue("invoice.total", 1250.75);

// Save generated document
docxMerger.save("generated_invoice.docx");

Extensive Barcode Support in DOCX

The open source DocxFactory library supports an extensive range of 1D and 2D barcodes, including Code39, Code128, EAN, UPC, ISBN, Databar, Postal Codes, PDF417, Data Matrix, QR Code, and Maxi Code. Barcodes are inserted as fields in templates and automatically rendered based on the data you provide. This makes it ideal for inventory management systems, shipping and logistics applications, product labeling solutions, document tracking systems, retail point-of-sale integration and so on.

The DocxFactory library can populate chart data dynamically, allowing you to create data-driven visualizations. Charts defined in your template can have their data series updated programmatically, making it possible to generate executive dashboards and analytical reports. The library has included support for complete list of more than 70 chart types available in Microsoft Word, including Column, Line, Pie, Bar, Area, Scatter, Stock, Surface, Doughnut, Bubble, Radar charts and so on. This feature enables dynamic financial reports with real-time data visualization, statistical analysis documents, business intelligence dashboards, scientific research reports, performance tracking documentation and so on.

Advanced Formatting and Styling in DOCX Files

The open source DocxFactory library maintain Word's native formatting while dynamically adjusting styles inside C++ applications. The library has included support for various formating features such as font styles, sizes, and colors, paragraph alignment and spacing, tables with custom borders, headers and footers, page numbers and section breaks, custom styles & themes, and so on. The generated document preserves all formatting from the template, ensuring consistent branding and professional appearance. The following code example shows how developers can apply conditional formatting base on data inside C++ apps.

// Advanced Conditional formatting based on data

item->setFieldValue("status.text", "OVERDUE");
item->setFieldValue("status.color", "#FF0000"); // Red color for overdue

// Dynamic table row formatting
for (size_t i = 0; i < invoiceItems.size(); i++) {
    if (i % 2 == 0) {
        item->setFieldValue("items.rowColor", "#F5F5F5");
    }
}
