CleanSheet AI vs Quadratic

CleanSheet AI is a standalone web tool for cleaning and normalizing CSV, XLS, and XLSX files without formulas. Users upload a file, choose a sheet when a workbook has several, review suggested changes, approve fixes, and download the result. It can split names, standardize dates and currencies, correct email formatting, format phone numbers, and detect duplicates. Files can be up to 1 GB, and approved operations appear in a change log. The maker says cleaned files can be prepared for HubSpot, Salesforce, and CRM imports. Processing uses isolated encrypted workflows, files are not used to train AI models, and data is isolated by account. Free support is by email; Pro includes priority support. The Free plan costs nothing and allows five files monthly, ten rows per file, and five AI analyses. Pro costs $15 a month.

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.
