AI Sheets offers two main ways of working with data. First, users can generate dataset structures and sample rows from scratch by typing in natural language descriptions, such as generating lists containing images of cities, countries, and landmarks. Second, the tool supports the import of existing files in XLS, TSV, CSV or Parquet formats, each containing up to 1,000 rows and unlimited columns, which can be expanded and enhanced using AI features after import. Both allow users to generate more rows of data with a simple drag-and-drop operation without having to regenerate the entire data set.
