Short answers to the usual questions.

Relationsheet is a relational spreadsheet suite: a familiar grid with a real relational database underneath, plus project management, accounting, and forms — all in the base product.

Yes. Import a CSV and Relationsheet turns it into a typed sheet. You can export any view back to CSV at any time.

Use Continue with Google, a magic link sent to your email, or an email and password. If you started as a guest, creating an account keeps the work you already did — and it is worth doing early: until you add an email, a guest workspace lives in that browser alone, with no password and no way to recover it if the browser's data is cleared.

Open Settings from the dashboard. You can update your display name and email there; email changes require confirming the new address.

Your dashboard groups sheets into Your sheets, Shared with you, and Via your groups — so shared and group-based access appear automatically as your membership changes.

Yes. Projects, accounting, and forms are part of the base product. Paid plans add collaboration, administrative control, and scale — not features locked behind a module.
