This script will let you selectively format text.

#target photoshop

layerUpdate();

function setFormatting(start, end, fontName, fontStyle, fontSize){
var idsetd = app.charIDToTypeID('setd');
var action = new ActionDescriptor();
var idnull = app.charIDToTypeID('null');
var reference = new ActionReference();
var idTxLr = app.charIDToTypeID('TxLr');
var idOrdn = app.charIDToTypeID('Ordn');
var idTrgt = app.charIDToTypeID('Trgt');
reference.putEnumerated(idTxLr, idOrdn, idTrgt);
action.putReference(idnull, reference);
var idT = app.charIDToTypeID('T ');
var textAction = new ActionDescriptor();
var idTxtt = app.charIDToTypeID('Txtt');
var actionList = new ActionList();
var textRange = new ActionDescriptor();
var idFrom = app.charIDToTypeID('From');
textRange.putInteger(idFrom, start);
textRange.putInteger(idT, end);
var idTxtS = app.charIDToTypeID('TxtS');
var formatting = new ActionDescriptor();
var idFntN = app.charIDToTypeID('FntN');
formatting.putString(idFntN, fontName);
var idFntS = app.charIDToTypeID('FntS');
formatting.putString(idFntS, fontStyle);
var idSz = app.charIDToTypeID('Sz ');
var idPnt = app.charIDToTypeID('#Pnt');
formatting.putUnitDouble(idSz, idPnt, fontSize);
textRange.putObject(idTxtS, idTxtS, formatting);
actionList.putObject(idTxtt, textRange);
textAction.putList(idTxtt, actionList);
action.putObject(idT, idTxLr, textAction);
app.executeAction(idsetd, action, DialogModes.NO);
}

function layerUpdate(){
if(documents.length > 0){
var originalDialogMode = app.displayDialogs;
app.displayDialogs = DialogModes.ERROR;
var originalRulerUnits = preferences.rulerUnits;
var j = 0;
try{
var docRef = activeDocument;
preferences.rulerUnits = Units.POINTS;
var m = 0;
for(var i = 0; i < docRef.artLayers.length; i++){

I have the code to update the existing characterStyle:
But Two things are need to be included:
1. Style name should be dynamic, instead of hard coding the style name, Because I need to apply it for all the character style in new master psd, since we don't now the Style name.

2. It replacing the properties what we given like Font and FontStyle and Size. But it removes all the other properties like leading.
Can you help me on this

var params = {

styleSheetName: "01 Headline SFP-D-SB 80/88/0 1d1d1f LRG" ,

fontPostScriptName: "MyriadPro-BoldIt" ,

fontName: "Myriad Pro" ,

fontStyle: "Bold" ,

size: 12.000000 ,

};

var desc1 = new ActionDescriptor();

var ref1 = new ActionReference();

ref1.putProperty( charIDToTypeID( "Prpr" ), charIDToTypeID( "TxtS" ) );

ref1.putEnumerated( charIDToTypeID( "TxLr" ), charIDToTypeID( "Ordn" ), charIDToTypeID( "Trgt" ) );

desc1.putReference( charIDToTypeID( "null" ), ref1 );

var desc2 = new ActionDescriptor();

desc2.putString( stringIDToTypeID( "styleSheetName" ), params.styleSheetName);

desc2.putString( stringIDToTypeID( "fontPostScriptName" ), params.fontPostScriptName);

desc2.putString( charIDToTypeID( "FntN" ), params.fontName);

desc2.putString( charIDToTypeID( "FntS" ), params.fontStyle);

desc2.putUnitDouble( charIDToTypeID( "Sz  " ), charIDToTypeID( "#Pnt" ), params.size);

desc1.putObject( charIDToTypeID( "T   " ), charIDToTypeID( "TxtS" ), desc2 );

executeAction( charIDToTypeID( "setd" ), desc1, DialogModes.NO );
