Hi @ricardosmenezes - I believe that if you’re in a region that uses decimal comma notation instead of decimal point notation, you would replace commas with semi-colons as you’ve done, with exception of inside curly braces like the first part of this formula. The curly braces { } are used for forming an array and the commas inside there need to be replaced with a backslash .
One other thing you could try is to go to File–>Settings–>General–>Locale and set the Locale for this sheet to your location and (I’m not 100% sure about it and can’t test it myself), but it might change these formula delimiters automatically for you. Hopefully it would, otherwise it seems like a lot of effort would be needed to go manually change all of the formulas. Let us know if you do that and if it works because I couldn’t seem to get a clear answer on that when making a simple Google search.
