Mail merge using C++

With our C++ solution you can create documents, personalized for each recipient, using the Mail merge feature in C++. To do this, just use the Mail merge template and data from the customer data source.

A merge template is a document with merge fields – special fields where you want personalized data from your data source to be inserted. As a merge template, use a PDF or Word document in DOC or DOCX format with special merge fields.

The data source is the data store from which data is pulled during the Mail merge operation to personalize your documents.

Generate reports

You can also build reports using the Mail merge operation. Just create a Mail merge template with merge fields that will be used for report generation and select the data source. You can even generate reports from excel data if you collect it there. So you see how easy it is to generate reports in C++.

Try to use Mail merge in C++

The following example shows how to perform a Mail merge operation in C++. To verify this, load a document template with merge fields and fill in these fields through our interface. After running the code, download the result of the Mail merge in a convenient format such as DOCX or PDF, generated in C++.

For example, you can perform Mail merge operation with Word document files such as DOC or DOCX and save the output to PDF:

Execute a Mail merge operation in C++
Upload a Mail merge template
Run code
Select the target format from the list
using namespace Aspose::Words;

auto fields = MakeArray<String>(
{
});
auto values = MakeArray<SharedPtr<Object>>(
{
});

auto doc = MakeObject<Document>(u"Input.docx");
doc->get_MailMerge()->Execute(fields, values);
doc->Save(u"Output.docx");
Run code
