Show HN: Delightful Cells – reliable AI batch processing for spreadsheets (delightfulcells.com)

A new tool, "Delightful Cells," has emerged to enhance batch processing for spreadsheets by utilizing AI technology. Users can upload Excel or CSV files and specify tasks for each row, allowing the system to process data seamlessly. Notably, the tool automatically retries failed batches and preserves completed rows, enabling users to rerun only those that encountered issues. This level of automation streamlines the data processing workflow without requiring a subscription, offering one-time credits that never expire. For the AI/ML community, the significance of Delightful Cells lies in its innovative approach to reliable data processing, combining the simplicity of classic spreadsheet tools with advanced automation. The solution operates entirely in the browser without an Excel add-in, ensuring user privacy by processing filtering, replacing, and calculations locally—only selected cell contents are sent to the AI for processing. This design not only improves efficiency but also minimizes data exposure, making it an attractive option for businesses looking to leverage AI in their data management tasks.
