About Thinkfree Document Editor SDK
Thinkfree Document Editor SDK, previously offered as Thinkfree Office, lets developers embed a full Office editor in web applications and control documents through object-level APIs. It supports Word, spreadsheet, and presentation editing for DOCX, XLSX, PPTX, and ODF files, without building an editing layer from scratch.
The SDK is designed to work as part of an application rather than as a separate Office product. Applications can combine interactive editing with programmatic document operations and AI workflows, allowing users to review and continue editing in the same editor.
• Embeddable Office editor UI for word processor, spreadsheet, and presentation documents
• 900+ Object-level APIs for paragraphs, tables, ranges, sheets, charts, slides, and shapes
• High-fidelity editing for DOCX, XLSX, PPTX, and ODF documents
• Document tools that LLMs or AI agents can invoke
• Real-time collaborative editing
• Self-hosted deployment, or a Thinkfree-managed cloud API
