With the addition of custom functions that can call each other and recursively call themselves, Excel's formula language becomes Turing-complete, effectively meaning that Excel users can compute anything without resorting to another programming language. ... You can't define new functions.

When did Excel become Turing-complete?

In December 2020, we announced LAMBDA, which allows users to define new functions written in Excel's own formula language, directly addressing our second challenge. These newly defined functions can call other LAMBDA-defined functions, to arbitrary depth, even recursively. With LAMBDA, Excel has become Turing-complete.

Is Excel Turing-complete without VBA?

Is word Turing-complete?

The answer is yes, but for an unexpected reason. I believe the above comments are correct — given size_t is bounded, you cannot represent a turing machine with unbounded states by using C as intended. However, we can use C in a way which completely circumvents the size_t issue — using only the C preprocessor.

What makes something Turing complete?

A Turing Complete system means a system in which a program can be written that will find an answer (although with no guarantees regarding runtime or memory). So, if somebody says "my new thing is Turing Complete" that means in principle (although often not in practice) it could be used to solve any computation problem.

Are all programs Turing complete?

Virtually all programming languages today are Turing-complete. The concept is named after English mathematician and computer scientist Alan Turing. ... Of course, no physical system can have infinite memory; but if the limitation of finite memory is ignored, most programming languages are otherwise Turing-complete.

How do you prove something is Turing complete?

Typically, one proves a given language is Turing-complete by providing a recipe for translating any given Turing machine program into an equivalent program in the language in question. Alternately, one can provide a translation scheme from another language, one that has already been proven to be Turing-complete.
