Runs fully offline — no external services or cloud dependencies. Your document generation stays reliable and completely in your control.

Integrate once, generate unlimited Office documents

Templater provides a stable, lightweight API and server-optimized architecture. Developers spend less time coding reports and more time on core applications.

Templater example: a carriage

// C#
using (var doc = Configuration.Factory.Open("Template.docx"))
  doc.Process(new { Tag = "a carriage" });

// Java
try (TemplateDocument doc = Configuration.factory().open("Template.docx")) {
  doc.process(new Object() { public final String Tag = "a carriage"; });
}

// Scala
val doc = Configuration.factory.open("Template.docx")
doc.process(new { val Tag = "a carriage" })
doc.close()

// Console
TemplaterJson.exe Template.docx < input.json > Document.docx

No additional code is required when templates change — only the Office file is updated.
