I want to make a webpage that fills a spreadsheet using a text context supplied by url hash. Either you open that page and copy data/text, or you can use a bookmarklet to provide the context scraping the page it is invoked from. You would define the spreadsheet columns. Name them but also be able to specify types/description/instructions. As you update the configuration, the spreadsheet content updates progressively using instructor php partial/stream support.
Support importing an existing spreadsheet/template to fill in columns. Use LLM to generate descriptions. WIll be better with sample rows.
Use browser extension to feed all pages content
