TEXTSPLIT is a function that combines multiple strings with the option for a separator, such as a comma, to be used.
For example, if you have three strings "apple", "banana", and "orange", using TEXTSPLIT with a comma separator would result in the output "apple, banana, orange".
The syntax for using TEXTSPLIT is: TEXTSPLIT(string1, string2, ..., separator)
Some programming languages may have built-in functions for this, while others may require writing a custom function to achieve the same result.
Overall, TEXTSPLIT is a useful function for combining strings together with a specified separator.
