Tablesmith is an AI-powered tool aimed at automating spreadsheet tasks, taming unruly data and stimulating creativity through its autofill feature. It offers spreadsheets as input/output components for the pipeline, unlike traditional spreadsheet editors. More than a spreadsheet tool, Tablesmith is designed to make data workflows less complex and data pipeline building more intuitive. Its automation stages include filter, sort, group, add column, update column, and data extraction, which can be combined to form complex pipelines. Tablesmith also integrates AI for summarizing, cleaning, or extracting data, and for creating personalized tools swiftly. It supports both CSV and XLSX formats for data input and output, and works across multiple platforms, including Web, iOS, macOS, and Windows. The tool's design grants privacy as a top priority, storing only pipelines for logged-in users while maintaining spreadsheet data solely on the user's device. Tablesmith comes with published web app pipelines for public use and editing, and features demo pipelines that showcase the application's capability to organize and process data efficiently.
