Mail merge for Word or PDF documents in C#

High-speed .NET library for merging document templates and user data into files of various formats

Our solution provides a powerful platform independent API. Use our Mail merge document API to develop high-level software for .NET and .NET Core platforms. This is a powerful software solution for merging templates in Word and PDF formats and data from custom data sources and further exporting the result to DOCX, PDF, HTML and other popular formats using C#.

Mail merge using C#

With our .NET solution you can create documents, personalized for each recipient, using the Mail merge feature in .NET. 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 .NET.
