In their own words
Quadratic
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.
XcelAI
XcelAI is an AI-powered Microsoft Excel add-in for creating formulas, transforming tables, cleaning data, generating charts, and analyzing spreadsheets through natural-language requests. In the Formula Assistant, users describe a need in plain English; XcelAI writes an Excel formula and inserts it into the sheet. Analyze & Clean can answer questions about data, highlight patterns, find duplicates, correct formatting issues, and provide insights. Smart Charts analyzes data structure and creates a chart with summarized data, while One-Click Reports produces executive reports with metrics, salesperson rankings, regional analysis, and data-quality checks. Forecasting creates monthly projections, growth rates, and confidence levels in a new forecast sheet; these three capabilities are Pro features. XcelAI runs on the web as an Excel add-in installed through Excel Online’s add-ins menu. Free includes 200 requests monthly, a 50-row limit, and five Pro-feature trials. Pro costs $9 a month or $89 a year.
