Good morning 
I have a job request on Excel, I hope someone can help me. 

I have a list of formulas and sequential links on one or more Excel sheets.
Is it possible to know if one formula is executed before another? Is there any Library or Tools that allows you to do this "operation"?

Thanks to who will answer

When evaluating a formula, Excel follows a standard math protocol called "order of operations". In general, Excel's order of operation follows the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction) but with some customization to handle the formula syntax in a spreadsheet.
