What it is

Quadratic is an AI-enabled spreadsheet that combines spreadsheet formulas with Python, SQL, JavaScript, live data connections and AI. Users can ask questions in plain English, then inspect and edit the formulas, code and charts AI generates in spreadsheet cells. It imports CSV, Excel, Parquet, PDF and Google Sheets files, and connects to sources including PostgreSQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid and Salesforce. Quadratic says a sheet can hold 100 million rows and can import multi-GB CSV and Parquet files. Its MCP server lets compatible AI tools read sheets, write cells and charts, and run Python, SQL and formulas; an API can trigger AI runs and read or write cells. Quadratic says data is stored and calculations run on the user's computer by default, and that its cloud service is SOC 2 and HIPAA compliant. Desktop apps are available for macOS and Windows, with a mobile UI for phones. Personal is free with limits; Pro costs $18.00 per month, billed annually.

Quadratic in depth

Read the full write-up

Overview

Quadratic is a spreadsheet built around analysis that can move between formulas, code, AI, and connected data. It suits individuals and teams who want generated work to remain editable; its breadth is appealing, but the free tier is limited and paid plans require annual billing.

Its mix of spreadsheet formulas, Python, SQL, and JavaScript gives data-minded users room to work in familiar cells and code in the same product. Plain-English prompts can generate formulas, code, and charts, with the result left in cells for inspection and revision. That makes Quadratic a stronger fit for people who want to refine AI-assisted analysis than for those seeking only a quick, finished answer.

Quadratic says one sheet can hold 100 million rows and supports multi-GB CSV and Parquet imports. It also imports Excel/XLSX, PDF, and Google Sheets, and exports Excel/XLSX, CSV, Quadratic/Grid, PNG, and PDF. Its connections directory includes PostgreSQL, Snowflake, BigQuery, QuickBooks, Google Analytics, Mixpanel, Plaid, and Salesforce.

Key features

AI-assisted spreadsheet work: Plain-English requests can produce formulas, code, and charts. Keeping the output in cells lets users check and edit it rather than treating the result as a black box.

Large-file support: The stated capacity of 100 million rows per sheet and multi-GB CSV and Parquet imports makes Quadratic relevant to users whose datasets outgrow ordinary spreadsheet workflows.

Connected data and automation: SQL connections and a broad range of named services can bring data into the workspace. The MCP server lets compatible AI tools read sheets, write cells and charts, and run Python, SQL, and formulas; the API can trigger AI runs and read or write cells.

Local processing and security: Quadratic says data is stored and calculations run on the user's computer by default, and that its cloud service is SOC 2 and HIPAA compliant. These are useful considerations for sensitive work, though they do not remove the need to assess a company's own requirements.

Collaboration and exports: Team collaboration is supported, and exports include spreadsheet formats as well as PNG and PDF, giving users options for continued editing or sharing a rendered result.

Pricing

Quadratic is freemium. The Personal plan has no stated price and offers limited AI usage, sharing, files, connections, and support. It is the entry point for individuals, but those limits may constrain anyone who relies on frequent AI work or broader collaboration.

Pro costs $18 a month (billed annually). It includes $20 in AI credits per month, additional privacy controls, and unlimited sharing, files, and connections. This is the clearest fit for shared-workspace users who need fewer restrictions on collaboration and data access, but the annual billing term is a meaningful commitment.

Business costs $36 a month (billed annually). It includes $40 in AI credits per month, the Pro features, and the option to purchase additional AI credits on-demand. Teams with heavier AI use may benefit from that higher allowance and top-up option; the price doubles Pro's monthly rate.

Enterprise has custom pricing and includes custom AI usage, Single Sign-On, a self-hosting option, and dedicated support. It is aimed at companies that need those controls or support rather than a standard individual or team plan. There is no free trial.

Platforms

Quadratic lists Android, iOS, macOS, Windows, web, API, and self-hosted availability. Its changelog describes standalone desktop apps for macOS and Windows and a mobile UI for phones. Self-hosting is offered on Business and Enterprise, with AWS and Docker listed as supported providers.

Who it's for

Quadratic is a good candidate for analysts and teams who want spreadsheet-style work alongside code, live data connections, and AI-generated output they can inspect and change. Personal is positioned for individuals; Pro for shared-workspace users; Business for teams needing more AI capacity; and Enterprise for companies seeking custom features and support. It is less compelling for someone who needs an inexpensive, unrestricted plan or does not need the combination of spreadsheet and analytical tools.

Pros and cons

Pro: AI output remains editable in cells, making it practical to review and refine generated analysis.

Pro: Support for large sheets, multi-GB imports, SQL, and named data connections brings substantial data work into one spreadsheet environment.

Pro: MCP and API capabilities extend the sheet to compatible AI tools and programmatic workflows.

Con: Personal has limits on AI usage, sharing, files, connections, and support, so it may not sustain regular collaborative work.

Con: Pro and Business are billed annually, and Business costs $36 a month before any additional AI credits.

Con: Enterprise's custom pricing makes it difficult to compare against standard per-user plans before engaging with the company.

Alternatives

Choose Julius AI if a freemium AI analysis tool with a Google Drive connector and free daily credits better fits your needs than a spreadsheet-centered workspace.

Byaan is an alternative with a free, MIT-licensed macOS app for individuals and a self-hosted team version.

Choose Chartt if its free plan's 100 monthly credits, files under 100 MB, one data source, and PNG and CSV exports are sufficient for your work.

ExcelGPT is another freemium option for AI data analysis, with a free plan offering up to 90 credits per month via daily check-in.

Consider Veezoo if a paid product with a free trial and support for up to 300 users is a better match.

PerSight is a desktop alternative for macOS and Windows, with a free plan capped at 15 questions per month, one database connection, and one device.

Choose Vizly if a web-based AI analysis tool with a Basic plan capped at 200 messages per month suits your usage.

Akkio is an alternative with a free plan and a custom-priced enterprise AI analytics platform.

For broader browsing, see AI Data Analysis Tools, Spreadsheet apps, or AI Spreadsheet Tools.

Verdict

Choose Quadratic if you want a spreadsheet that combines formulas, code, connected data, and AI output you can inspect and edit. Its capacity and integration range are strong reasons to consider it for analytical work, but limited Personal features and annual billing on Pro and Business are reasons to look elsewhere if flexibility or a low-commitment plan matters more.

Verdict

Quadratic joins spreadsheet work with code, AI and live data connections, while keeping generated analysis editable in cells. The free plan has stated limits, and the listed Pro price is billed annually.
