Make money with it
A freelance developer could build and sell custom document editing or report automation tools for clients using these libraries.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Add document editing and collaboration to a client portal or SaaS product without paying for a per-user Office licence or a document editing SDK
- Automate generating and updating Word, Excel and PowerPoint reports on a server for clients
Can you use it commercially?
Free to use, change and sell, including in paid products. Keep the copyright notice.
Not legal advice. Read the project's licence file before building a product on it.
Getting it running
You install it as packages from npm, crates.io or PyPI and write code to build it into your own app.
Follow the official instructions in the project README.
Things to check
- It is a developer library, not a finished app, so it needs coding to use
- Version 0.5 suggests the API is still changing
- Rendering fidelity compared with Microsoft Office may vary on complex documents
