Cell Artisan converts images into Excel cell art. Pick a photo or illustration, adjust the cell count, color count, and cell size, then export a real .xlsx file made from colored spreadsheet cells. The export is not a pasted image. Use it for pixel-art style images, logos, character art, social posts, and spreadsheet experiments. Files can be shared through Mail, Files, cloud storage, and other apps. Image processing and workbook creation run on device. Selected images are not uploaded to an external server.
