Relationsheet puts a real relational database under a familiar grid — link your tables instead of duplicating data. Project management, accounting, and forms are included in the base product, not sold as add-ons.
No credit card required. Bring a CSV and see it become a database.
Why Relationsheet
Keep the grid your team already knows, and gain the structure, relationships, and governance of a database underneath it.
Columns are typed, rows are records, and relationships are first-class — the structure of a database with the ease of a grid.
Point one sheet at another and pull fields through. Change a value once and every linked view updates — no copy-paste drift.
Sum a customer's invoices, count a project's open tasks, surface a linked field — computed live from the relationships you draw.
Sheet, row, and column permissions by person or group — including conditional access on a cell's value — enforced in the database, not the UI.
The suite
No stitching five tools together. The database, the project plan, the ledger, and the forms all share the same connected data.
A fast, familiar grid with typed columns, formulas, formatting, and undo/redo.
How — Start typing — it works like a spreadsheet.Tables, link fields, lookups, and rollups turn flat sheets into a connected model.
How — Add a relation column to link rows across sheets.Gantt with critical path and dependencies, Kanban boards, calendars, and timelines.
How — Switch any sheet into a Timeline or Board view.Currency columns, rollups, and cross-sheet totals for invoices, AR, and budgets.
How — Roll up line items into a running balance.Publish a form that writes straight into a sheet — no separate tool to wire up.
How — Turn a view into a public form in one click.When a row changes, set a value, create a linked row, notify, or call a webhook.
How — Deal won → create the invoice, automatically.CSV in and out, plus a REST API and webhooks to connect the rest of your stack.
How — GET and POST rows with an API key.Per-sheet/row/column access by user or group, conditional rules, and a tamper-evident audit trail.
How — Grant read on rows where Region = a user's region.Built for every team
Run programs on linked trackers — projects, tasks, risks, and resources that stay in sync across teams.
Invoices linked to customers, line items rolled into totals, budgets versus actuals in one base.
A pipeline where deals link to accounts and contacts, and a won deal spins up onboarding automatically.
Campaign calendars, request forms, and content plans feeding the same connected data.
A governed source of truth with an API, permissions, and audit — without standing up a warehouse.
How it works
Create sheets and connect them with relation columns — customers to invoices, projects to tasks.
The same records as a grid, a board, a calendar, a Gantt, or a public form — no data duplicated.
Lookups and rollups compute across relations; automations and the API keep everything moving.
Pricing
No paywalled modules for projects, accounting, or forms. Plans differ by collaboration, governance, and scale.
For individuals and small trials.
For teams building a shared source of truth.
For governed, cross-department deployments.
Start with a CSV or a blank base. Link your tables, invite your team, and keep the tools you already know.
