Ask HN: The best, preferably open source, JavaScript spreadsheet out there?

Which one is the best and why ? Does it support data search ? Can it do validation ? Does it handle well with thousands and thousands of rows ? Are their docs full and up to date ? I've been looking around at https://ift.tt/3IJ4425 and tried many of them, but still can't put my finger on which one to go with. My requirements are more on the viewing/grouping/searching side rather than editing/formulas etc. but any impressions will help.
