replace space with comma for words that only have space between them regex

Question

I trying to replace spaces with comma for words that only have space between them like this example

Color : NavyBlue TrainLength : FloorLength USSize : 6 shipping : standard

it should be like this

Color : NavyBlue,TrainLength : FloorLength,USSize : 6,shipping : standard

where it has commas between these variants

I can only match spaces between words that have colons

\s*:\s*

but I need a way to match spaces between words that has no colon

for example consider the dots as space

don't match this ...:...

but match this NavyBlue.....TrainLength

match the spaces only not the words

to test it test real example

@ASDFGerte didn't work try from the link I updated in the question — Programming Skills

Well, if you change the format, of course a regex written for the original one is highly likely to not work... — ASDFGerte

@ASDFGerte What I need is to match the space between the variants to replace it with comma like the example I updated but in your example it will match (words space words ) which I don't want to match any words — Programming Skills

This should work:

let s1 = " Color  :  NavyBlue      TrainLength : FloorLength  USSize : 6   shipping";
let r1 = s1.replace(/(\w+)\s+(\w+)/g, "$1,$2");
console.log(r1);

let s2 = "Color : NavyBlue TrainLength : FloorLength USSize : 6 shipping : standard";
let r2 = s2.replace(/(\w+)\s+(\w+)/g, "$1,$2");
console.log(r2);
