Earlier quoted context omitted.

Your issues are mostly with the file picker, which is a brand new component that was just added yesterday in response to a feature request after launch: https://x.com/andrewlu0/status/2064726998186971400?s=46 It has some rough edges as a result, but your suggestions are very valid. We’ll make those improvements (we’re also taking PRs!).

Nice! That explains it to a degree. I would suggest taking someone who is really annoying about details, from your team, and having them just use the components as they are. Just click around and mess with them for a while -- in my experience this is how you get that final 20% of polish.

Cool project! I was playing around with the Excel viewer - the docs claim "Search across sheets and cell ranges", but I can't seem to trigger search functionality and the browser search bar can't find contents on cells. Is this a known issue?

just added an example implementation in the xlsx viewer for search, but the code is yours to modify and customize. react-xlsx should expose the necessary functions to implement a custom search (by workbook/sheet etc...)
