// The following sample illustrates how to use ConvertOfficeToPDF
// to convert MS Office files to PDF and replace templated tags present in the document
// with content supplied via json
// For a detailed specification of the template format and supported features,
// see:
// This conversion is performed entirely within the PDFNet and has *no*
// external or system dependencies -- Conversion results will be
// the same whether on Windows, Linux or Android.
// Please contact us if you have any questions.
