Quadratic is a collaborative AI spreadsheet that combines familiar cells and formulas with Python, JavaScript, SQL, database connections, charts, and natural-language analysis.
Direct verdict
Shortlist Quadratic for teams that want code and AI inside a collaborative spreadsheet. Keep source queries and generated code reviewable, reconcile decisive totals independently, restrict database credentials, and prove workbook compatibility before replacing an established spreadsheet stack.
What to verify
Import 30 representative workbooks and rebuild three recurring analyses using formulas, Python, SQL, and AI. Seed missing values, type errors, altered source schemas, malicious cell text, and contradictory totals. Compare outputs to known answers; measure compatibility, reproducibility, review time, connection security, collaboration conflicts, and credit cost.
