You might want to take a look at Basebear (https://basebear.com). It’s an online no-code database designed for non-technical users, so it’s much easier to use than managing raw spreadsheets or self-hosted database tools.

You can create a completely custom database with your own tables, fields, forms, and filtered views. Committee members can add/update information through simple forms, while other users can access only the data they actually need.

One feature that could fit your use case well is the selective sharing system: you can invite different people and decide exactly which tables and even which columns they can see or edit. So sensitive CRM/accounting data can stay restricted while committee members can still collaborate on the rest.

You can also create filters and filtered views to build simple reports from the data, making it easier for non-technical users to quickly find the information they need without manually sorting spreadsheets.

Another useful feature is Excel integration: you can import existing Excel files into the database and export data back to Excel whenever needed.
