How to convert numbers to letters - google-sheets

Question

I have a sheet that shows Items Cost. What I want to do instead of showing numbers i want to use the following BLACKHORSE were B = 1, L = 2, A = 3,C=4,K=5,H=6,7=O,8=R,9=S and E=0. How do i put this in a script in Google Sheets to where say cell h9 the sum of the total cost of the items it puts the letters instead of numbers

There may be many ways to calculate the values that you want. Consider this as one approach.
function so5715442701() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
var sheetname = "57154427";
var sheet = ss.getSheetByName(sheetname);
// code to find the key for a given value in a javascript key:value array
Object.prototype.getKey = function(value){
for(var key in this){
if(this[key] == value){
return key;
}
}
return null;
};
// a key:value array for BLACKHORSE
var blackhorse = {
B : 1,
L : 2,
A : 3,
C : 4,
K : 5,
H : 6,
O : 7,
R : 8,
S : 9,
E : 0
};
// get the cost value from a cell
var costprice = sheet.getRange("C15").getValue();
// convert the number to a string
var cost = costprice.toString(); // convert to string
//Logger.log("DEBUG: cost = "+cost+", length = "+cost.length);
// set a variable to accumulate the results
var costtotal="";
// loop through the characters in the cost value
for (var i = 0; i < cost.length; i++) {
var letter = cost.charAt(i);
var costkey = blackhorse.getKey(letter);
var costtotal = costtotal+costkey
}
//Logger.log("DEBUG: cost = "+cost+", Blackhourse cost = "+costtotal);
sheet.getRange("D15").setValue(costtotal);
}
