Google Sheets - Auto Find & Replace - excel

Question

I have a large spreadsheet that imports basketball statistics from various websites throughout the day and then index-matches them in other tables. My problem is that some websites use a name like "Lou Williams," while others use "Louis Williams." Each time I update one of the tabs with new data, I have to manually correct all the discrepancies between names. Is there a way to write a script that auto corrects the 10-12 names that I am constantly having to fix? I'd love to find some way to do this that is easier than doing a "Find & Replace" 10 different times.
I'd also love if these "spell checks" would happen only on 3 specific tabs, but would also be ok if it happened across the entire worksheet.
I've done some research for a solution but I'm so new to scripting that it's hard to for me to translate other people's code.
Here is a (current) list of the names I frequently have to correct
INCORRECT CORRECT
Louis Williams Lou Williams
Kelly Oubre Kelly Oubre Jr.
Patrick Mills Patty Mills
James Ennis James Ennis III
Alex Abrines Álex Abrines
Guillermo Hernangomez Guillermo Hernangómez
Ishmael Smith Ish Smith
Sergio Rodriguez Sergio Rodríguez
Larry Nance Larry Nance Jr
Luc Mbah a Moute Luc Richard Mbah a Moute
Juan Hernangomez Juancho Hernangómez
Glenn Robinson Glenn Robinson III

Answer 1

There are other ways to do this, but this uses a 'Name List' sheet with correct and incorrect names. Run 'fix' from the custom menu and column A names will change the names to the correct ones. Here is the code and a sample spreadsheet you can copy and run.
function onOpen() {
SpreadsheetApp.getActiveSpreadsheet().addMenu(
'Correct Names', [
{ name: 'Fix', functionName: 'changeNames' },
]);
}
function changeNames() {
var ss=SpreadsheetApp.getActiveSpreadsheet()
var allSheets = ss.getSheets() //get all sheets
var numSheets=allSheets.length
var s=ss.getSheetByName("Name List")//get the list on names to change.
var lr=s.getLastRow()
var rng= s.getRange(2, 1, lr, 2).getValues()
for(var k=0;k<numSheets;k++){//loop through sheets
var s1=ss.getSheets()[k]
var test =s1.getSheetName()
if (s1.getSheetName()== "RG" || s1.getSheetName()=="NF" || s1.getSheetName()=="SWISH"){ //Sheets to process. '||' is OR
var lr1=s1.getLastRow()
var rng1=s1.getRange(2, 1, lr1, 1).getValues()// Assumes names start on eow 2 Column A. Adjust as needed
for(i=0;i<rng1.length;i++){
for(j=0;j<rng.length;j++){
if(rng1[i][0]==rng[j][1]){//if incorrect names match
rng1[i][0]=rng[j][0] //replace incorrect name with correct name
}}}
s1.getRange(2,1, lr1, 1).setValues(rng1)//replace names
}}}

Changed to only run certain sheets.
