MicrosoftI have made some add-ins available at https://xlladdins.com/. The https://xlladdins.github.io/xll_array/ add-in only works for numerical ranges. It uses the https://github.com/xlladdins/xll#fp-data-type data type behind the scenes for high-performance numerical computing. The https://xlladdins.github.io/xll_regex/ add-in is quite basic and not easy to use unless you know regular expressions. The intended audience is expert Excel users and only works for Excel on Windows.
The add-ins and installer are signed, but you will have to jump through the usual security hoops the first time around. It uses https://docs.microsoft.com/en-us/visualstudio/deployment/clickonce-security-and-deployment?view=vs-2022 so you will be notified of updates as they become available.
