Developed and delivered the Export Table to Excel feature for the CherryHQ/cherry-studio repository, enabling users to export markdown tables as .xlsx files through a dedicated toolbar button. The implementation leveraged React and TypeScript, introducing a new exportExcel.ts utility and integrating user feedback via toast notifications alongside robust error handling using a logger service. Comprehensive unit and end-to-end tests were created to validate markdown parsing and UI behavior, ensuring reliability across edge cases. The work also included synchronizing internationalization translations and improving dependency management by updating xlsx usage, contributing to enhanced project stability and a more seamless user experience.
