A spreadsheet with database power
Calc is more than a spreadsheet. It combines the flexibility of a spreadsheet with a relational database. Made for budgets, planning, and data collection.
# Custom views
Display data your way.
Show the same information as a table, calendar, or chart. Switch views as your needs change.
# Forms
Collect data without the copy-paste.
Build forms that feed responses straight into your spreadsheet.
# Relational spreadsheets
Link your data.
Connect tables and records, just like in a database. No duplicated information, no broken references.
Automation
Set up rules that act when data changes. Send a notification or update related records.
AI assistant
Write formulas and analyse data with built-in AI support.
API and integrations
Connect Calc to other systems via API or ready-made integrations.
Part of Collective Tools
Calc is part of the Collective Tools subscription. You don’t have to choose, you get access to the whole suite.
Used by the French public sector
Calc is part of France’s national open source programme for the public sector, LaSuite Numérique. LaSuite launched in 2024 and is already used by 15 French ministries. Part of the same suite as Notes, Meet, and Drive.
