Thinkfree Document Editor SDK

Thinkfree Document Editor SDK embeds a full Office editor into web applications and exposes object-level APIs for document content. It supports Word, spreadsheet, and presentation editing across DOCX, XLSX, PPTX, and ODF files. The SDK was previously offered as Thinkfree Office.

Object-Level Document Control

The SDK provides over 900 API methods for document objects, including paragraphs, tables, ranges, sheets, charts, slides, and shapes. Applications can read and modify content, apply formatting, and perform document operations programmatically.

AI Agent Integration
Document operations can be exposed as tools for an LLM or AI agent. AI workflows apply changes through the same object-level APIs, and users review and continue editing the result in the same embedded editor rather than a separate copy of the file.

Embedded, Not Standalone
The SDK operates as a component of a host application rather than as a separate office product. It integrates document editing into vertical AI services, groupware, ERP, PLM, and other enterprise applications without directing end users to an external Office application.

Deployment
The SDK deploys with Docker in customer-managed infrastructure, including on-premise and air-gapped environments, or through a Thinkfree-managed cloud API.
