Hi inglor! As someone who has been writing spreadsheets engines for the last 10+ years I am a big fan of how Excel has taken the lead in innovation in the last couple of years with dynamic formulas and the LAMBDA. So congratulations on your part of it! BTW, I must have been interesting to find an algorithm that can evaluate the new dynamic formulas. I would like to see one day more public information on spreadsheet evaluation algorithms. As the people from sourcetable[1] put it: > Spreadsheets are one of the hardest things you can build — right up there with compilers. I think I would like to see a "democratization" of the technology and find books, and lectures about it as popular as we find books and lectures about compilers. As for the OP I find their take interesting, of course you can accomplish that with more established tools but it was a refreshing read and an interesting, if not inspiring, notation. PS: Is it possible that there is a regression when computing sheets with lots of open ranges (like =SUM(D:D)) [1]: https://www.sourcetable.com/jobs https://www.sourcetable.com/jobs
