ChatExcel, an AI tool for use in Microsoft Excel that can conduct automatic calculations based on prompts without the need to manually set up formulas, has been created by a team from Peking University. The tool was launched this February, but gained widespread public attention and media coverage after Peking University published an article on the founding team on Tuesday. Yuan Li, leader of the team and also an assistant professor at the Beijing institution, said ChatExcel was developed to make specialized software like Excel easier to use. The AI-powered tool is available for free on the ChatExcel official website, with no limit on the number of times it can be used. [Peking University, in Chinese]
