Delightful Cells Brings Reliable Bulk AI Processing to Excel and CSV

Summary

Delightful Cells is a browser-based tool for applying AI to large Excel and CSV files. Users upload a spreadsheet, describe what each row needs, and receive a completed result, with support for .xlsx, .xls, and .csv files. Its batch system automatically retries failed batches, preserves completed rows, and lets users rerun only the rows that failed. A single conversation can contain up to eight steps per turn, while the service also offers one-job tools for extracting, comparing, finding duplicates, or pulling numbers from spreadsheet cells. Filtering, replacing, and calculations run locally in the browser; the product says AI receives only the selected cell content for processing. The service uses one-time credits rather than a subscription, and credits do not expire. It also provides demo data and works without an Excel add-in. The page does not specify the underlying AI model, output limits, or supported file-size limits.
