Use Regex to Replace Spaces In a Table Column

I have a table column that contains a variable quantity of spaces in each cell.  I want to collapse those to a single space.  I presume regex can eliminate those but I've never applied regex outside a column formula.  Is this even the best approach and if so, how do I achieve it?

Re: Use Regex to Replace Spaces In a Table Column

Collapse Whitespace() is basically meant for this (you can also use other methods)

Names Default To Here(1);

mystr = "a         b";

res1 = Regex(mystr, " +", " ", GLOBALREPLACE);

res2 = Concat Items(Words(mystr, " "), " ");

res3 = Collapse Whitespace(mystr);

show(res1, res2, res3);

Recode has Collapse Whitespace so you can just use that

and it will provide you with a script

// Recode column: Column 6
Local({dt},
	dt = Data Table("Big Class");
	dt << Begin Data Update;
	For Each Row(dt, dt:Column 6[] = Collapse Whitespace(dt:Column 6));
	dt << End Data Update;
);
