During October 2025, contributed to the dream-num/univer repository by developing a feature that normalizes URLs for hyperlinks within the sheet editor. This enhancement, implemented using TypeScript and front-end development techniques, ensures that URLs entered into cell hyperlinks are consistently formatted, reducing the risk of malformed links and improving overall data integrity. The approach involved integrating URL normalization directly into the cell editing workflow, allowing users to edit hyperlinks with greater confidence and reliability. By aligning hyperlink handling with robust content editing standards, the work supports safer spreadsheet edits and simplifies future maintenance, directly addressing workflow requirements discussed in project collaboration.
