Make money with it
A freelance developer could build custom spreadsheet-based tools or reporting portals for clients and charge for the build and upkeep.
An idea, not financial advice. Check the licence before charging for anything built on it.
Ways a business could use it
- Add spreadsheet-style data editing to a SaaS product or client portal instead of paying for a hosted editor
- Build internal reporting dashboards or document tools that staff can edit directly in the browser
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
It is installed as npm packages, either as ready-made presets or as individually chosen plugins, and then wired into your own web or Node.js project.
Follow the official instructions in the project README.
Things to check
- The README refers to a separate Pro offering, so check which features are open source
- Some related projects mention their own SDK licensing requirements
- Needs programming knowledge to use; it is not a ready-made app
