Using body.replaceText() to replace specific areas of a Google Doc with data from a Sheet. Three parts:
1. Replace data directly on a Doc
2. Make a copy of the Doc (template) then replace data on the copy
3. Loop through several rows of Sheet data, make a copy of the Doc (template) for each, then replace data on the copy

Important notes:
* Make sure the IDs for the Doc and the Folder are correct to your environment.

Scripts:
function first(){

const sheet = SpreadsheetApp.getActive().getActiveSheet();

let data = sheet.getRange(2,1,1,7).getValues();
let replacements = [“//PROJECT NAME//”,”//DATE//”,”//NAME//”,”//COMPANY//”,”//PROPOSAL//”,”//LOCATION//”,”//AMOUNT//”];

for (let i in replacements){
body.replaceText(replacements[i],data[0][i]);
}
}

function second(){
const sheet = SpreadsheetApp.getActive().getActiveSheet();
let data = sheet.getRange(2,1,1,7).getValues();

const file = DriveApp.getFileById(“1js6PIpBM9QBjR4o5rtDFq9_twSv7RPIQ1h0j5osHgTE”).makeCopy(“Project Proposal: “+data[0][0],DriveApp.getFolderById(“1osc-Ho5UCCjda6PiRtYtvcYvc3SDF_5X”));
