You can use ONLYOFFICE Document Builder to build any type of 32-bit or 64-bit application.

Independence from Other Applications​

ONLYOFFICE Document Builder does not require third-party applications. All Aspose components are completely independent. This makes ONLYOFFICE Document Builder a great alternative to automation in terms of security, stability, scalability/speed, price, and features for working with documents and related tasks.

Performance and Scalability​

ONLYOFFICE Document Builder is designed to perform greatly on both a server or client. ONLYOFFICE Document Builder is a single library. You do not need to worry about any other services, modules or libraries.

With ONLYOFFICE Document Builder, you can literally generate thousands of documents in minutes, which involves opening a document, modifying content and formatting or populating it with data, and saving it. Even most complex documents are opened and saved in fractions of a second.

ONLYOFFICE Document Builder is multithread safe as long as only one thread works on a document at a time. This is a typical scenario to have one thread working on one document. Different threads can safely work on different documents at the same time.

Minimal Learning Curve​

Although there are over 150 public classes and enumerations in ONLYOFFICE Document Builder, the learning curve is minimal because the ONLYOFFICE Document Builder API has been carefully designed with the following goals in mind:

  • Borrow best practices from other well-known APIs
  • Provide a balance of ease of use and detailed manipulation of document elements
