applescript : add clipboard content to list
Let's say my clipboard is &quot;name email phone&quot; and any random text and numbers.
Can the words be separated and added in a list?

You don't realise it, but you've answered your own question.
TL;DR
Say your clipboard contains the string &quot;Kevin stackexchange.com 124098&quot;.  Separate this into a list of words like so:
words of (the clipboard) --&gt; {&quot;Kevin&quot;, &quot;stackexchange.com&quot;, &quot;124098&quot;}

You can read more about this builtin AppleScript feature below, where I've given a detailed explanation, including why, sadly, this won't be quite as effective if an email address is involved:
words of &quot;Kevin@example.com&quot; --&gt; {&quot;Kevin&quot;, &quot;example.com&quot;}

So you'll either need to remember to restore the obliterated &quot;@&quot; symbol later; or, as you suggested, use text item delimiters set to a space character.
Detailed Information: text item delimiters vs words
AppleScript text objects are comprised of word and character elements that subdivide one another into the component building blocks of any string: text subdivides into words and/or characters; a word subdivides into characters.
Moreover, the words subdivide text at intervals marked by whitespace of any length, which is much more convenient than text item delimiters, which will split a string at each individual occurrence of a specified delimiter.
For example, setting text item delimiters to the space character, and applying it to a two-word phrase with three spaces between them, you'll end up with this:
text items of &quot;foo   bar&quot; --&gt; {&quot;foo&quot;, &quot;&quot;, &quot;&quot;, &quot;bar&quot;}

However, obtaining instead the words that make up the string avoids having to deal with empty-string list items:
words of &quot;foo   bar&quot; --&gt; {&quot;foo&quot;, &quot;bar&quot;}

Moreover, like text items, words of a text object will subdivide the string naturally into a list of individual items.
For completeness, I'll quickly demonstrate how characters will decompose a string:
characters of &quot;foo&quot;       --&gt; {&quot;f&quot;, &quot;o&quot;, &quot;o&quot;}
characters of &quot;foo   bar&quot; --&gt; {&quot;f&quot;, &quot;o&quot;, &quot;o&quot;, &quot; &quot;, &quot; &quot;, &quot; &quot;, &quot;b&quot;, &quot;a&quot;, &quot;r&quot;}

A bit of caution is warranted when decomposing a string into words, believing it operates identically (or near enough) to a space delimiter.  It doesn't.  There are a defined set of characters that are considered &quot;word characters&quot;, and a set of characters that are not.  &quot;Word characters&quot; are any character that, when grouped together, are considered word-forming.  If any non-word character appears, the word is considered split into two distinct words at that character.
Word characters basically include the letters A-Z and a-z (and any accented variants), numbers 0-9, the period (.) and the underscore (_).  So &quot;tH1s&quot; is a word, and &quot;this_is_a_single_word.123&quot;.  However, &quot;this#is%four words&quot;, and, counterintuitively to me, &quot;over-achieving&quot; is considered two words (the hyphen is a non-word character).
Other non-word characters obviously include the space; or any whitespace for that matter.  Plus any symbol you can type with your keyboard that wasn't included in the list of word characters, except the dollar sign ($), which I annoyingly left to now to mention just to reflect how annoying it is that it's randomly considered a word character:
words of &quot;hello#$&amp;world&quot; --&gt; {&quot;hello&quot;, &quot;$&quot;, &quot;world&quot;}
