What the Engine Does

The same engine LynxOffice runs on, without the app around it.

Reads and Writes the Real Files

Opens .docx, .xlsx, and .pptx into a structured model and saves them back in the same format. Parts you did not change are carried over untouched.

Renders Pages

Draws any page of a document, workbook, or deck to an image or to PDF.

Calculates Formulas

Evaluates spreadsheet formulas, with Excel-style error values returned as values.

Stays on the Device

No network calls, including for the licence check, so documents never leave your software.

Frequently Asked Questions

Who is ComOfficeKit for?

Developers who need to read, create, or show Office documents inside their own app, and companies building internal tools that work with those files.

How is it licensed?

Under contract, quoted by our sales team. There is no store or self-serve purchase; write to support@comofficekit.com and tell us what you are building.

Which platforms are available?

iOS, iPadOS, and macOS today. Other platforms will get SDKs of their own.

What does it not do?

It does not open or edit PDF files, although it renders documents to PDF, and it has no user interface of its own: you build the screens, and the SDK supplies the document model and draws the pages.
