Encoding combined text fields to Numeric Sequences

There are several problems with your proposed encoding:

(1) what happens to upper case letters or characters outside the range a-z?

(2) your encoding "10312222850417118122" for "a catthe doga rat" is wrong as "t" is the 20'th letter of the alphabet not the 22'nd. There are more errors later in the string.

(3) if you intend to decode your string at some point it isn't clear how say the sub-string "22" would be decoded as it could be "bb" or "v".

In any event this fragment of code patches some of these issues and deals with issue (3) by inserting a space delimiter between the encodings for individual characters:

var string = "a catthe doga rat".toLowerCase();
string =  string.replace(/./g, function(c) {
  var charCode = c.charCodeAt(0);
  if (charCode == 32) {
    return 0 + " ";
  } else {
    return c.charCodeAt(0) - 96 + " ";
  }
});
console.log(string);
//output:
//1 0 3 1 20 20 8 5 0 4 15 7 1 0 18 1 20 

The set given was an example. 22 was a miscount on my tired and worn out part. I will not be decoding it. It is for the numerical need only. 

Looking more to this: ([ToText] is already all lowercase, no space, concatenated text string from 3 different fields)

var text String = [ToText];

I need it to be numbers with no spaces between (so we can nix the +" "'s)

For some reason, it keeps throwing errors.  not liking any of the .'s

Any links to any help articles or formulas would also be helpful. I have found lots of articles on different solutions, and none seem to work. :(

Would this work for you? It combines the three fields, replaces space with 0 (though I note that this may be redundant now) and lowercase letters with a numerical equivalent. Note it will leave all other characters (such as numerics, uppercase, symbols, letters with accents, etc.) unchanged.

var text combined = [text1] & [text2] & [text3];
var text space = SearchAndReplace($combined, " ", "0");
var text a = SearchAndReplace($space, "a", "1");
var text b = SearchAndReplace($a, "b", "2");
var text c = SearchAndReplace($b, "c", "3");
var text d = SearchAndReplace($c, "d", "4");
var text e = SearchAndReplace($d, "e", "5");
var text f = SearchAndReplace($e, "f", "6");
var text g = SearchAndReplace($f, "g", "7");
var text h = SearchAndReplace($g, "h", "8");
var text i = SearchAndReplace($h, "i", "9");
var text j = SearchAndReplace($i, "j", "10");
var text k = SearchAndReplace($j, "k", "11");
var text l = SearchAndReplace($k, "l", "12");
var text m = SearchAndReplace($l, "m", "13");
var text n = SearchAndReplace($m, "n", "14");
var text o = SearchAndReplace($n, "o", "15");
var text p = SearchAndReplace($o, "p", "16");
var text q = SearchAndReplace($p, "q", "17");
var text r = SearchAndReplace($q, "r", "18");
var text s = SearchAndReplace($r, "s", "19");
var text t = SearchAndReplace($s, "t", "20");
var text u = SearchAndReplace($t, "u", "21");
var text v = SearchAndReplace($u, "v", "22");
var text w = SearchAndReplace($v, "w", "23");
var text x = SearchAndReplace($w, "x", "24");
var text y = SearchAndReplace($x, "y", "25");
var text z = SearchAndReplace($y, "z", "26");
