Univer Office SDK brings six composable content types into one runtime. Embed an individual editor or combine them in an Office application, with shared APIs for your users and agents.
Spreadsheets with formulas, formatting, filters, charts, and pivot tables. |
Rich-text documents with page layouts, tables, images, headers, and footers. |
Presentations with editable text, shapes, charts, themes, and slide playback. |
Relational tables with typed fields, linked records, formulas, and multiple views. |
Free-form canvases for whiteboards, diagrams, shapes, connectors, and mind maps. |
PDF viewing and editing with page operations, annotations, export, and printing. |
The open-source core, including Sheets and Docs capabilities, is Apache-2.0. The demos also include Univer Pro and other commercial SDK modules, which are licensed separately. See the feature comparison for coverage.
