Quadratic

What it does

Quadratic is a spreadsheet that takes in data from sources such as databases, CSV, Excel and PDF files, QuickBooks, Google Analytics and Mixpanel, and combines them into one live sheet. Users ask questions in natural language, and the AI produces formulas, Python and SQL cells, and results that sit in the sheet where each step can be opened and checked.

People use it to analyze large tables, build forecasts and dashboards, and automate refreshing financial or personal finance data. Its distinct features are AI-written code you can open and edit cell by cell, and an MCP server so agents such as Claude, Cursor or ChatGPT can read and write to a Quadratic sheet, with each change approved by the user.

Quadratic suits individuals and teams that work with spreadsheet data and want to inspect the code behind AI-generated analysis. Its free Personal plan limits AI usage, sharing and connections. Pro and Business add larger monthly AI credit allowances and shared workspaces, while Enterprise offers options such as self-hosting and single sign-on. The browser workspace also exposes API and MCP access for connected tools. Review generated code and data changes before using an analysis, particularly when a forecast or financial report depends on its assumptions.

What it can do

• Connects live to databases such as Postgres, MySQL and Snowflake, and to files like CSV, Excel and PDF.
• Runs AI-generated Python and SQL cells whose code can be opened and edited.
• Asks questions in natural language to generate formulas and spreadsheet edits.
• Handles large datasets, stating support for 100 million rows in one sheet.
• Exposes an MCP server so external agents can read and write spreadsheet cells.
• Provides a REST API for triggering AI runs and reading or writing cells.

Works with

• PostgreSQL
• MySQL
• Snowflake
• BigQuery
• Supabase
• QuickBooks
• Google Analytics
• Mixpanel
• Model Context Protocol (MCP)
• Plaid

Example workflows

Analyze a database table with natural language

Illustrative example. Input: a live Postgres connection and a question such as which segments drive revenue. Steps: connect the database with SQL, ask the AI chat for the grouping, then open the generated Python cell to check it. Output: a sheet table of top segments that can be re-run as data refreshes.

Let an external agent update a forecast sheet

Illustrative example. Input: a Quadratic sheet and an MCP-enabled agent such as Claude. Steps: point the agent at the sheet through MCP, ask it to write revised values, then review and approve each change. Output: updated cells with an audit trail of what was changed.

Before you choose

• The free Personal plan limits AI usage and sharing; unlimited shared files require Pro.
• AI usage is metered through monthly credits, with Business offering on-demand purchases beyond its included amount.
• Self-hosting, SSO and custom AI usage are listed only under the custom-priced Enterprise plan.
