How do you loop through an object and replace text

Question

I have a script that should create a pdf file from a google form submission and grabs the data to be changed as an object. However I am using the replaceText action to make the changes to the doc and I'm getting the following error.

Exception: Invalid argument: replacement at Create_PDF(Code:37:8) at After_Submit(Code:13:19)

It is supposed to change the values in the generated doc file and it worked when I used the namedValues function. However now that I'm using range instead it doesn't seem to work.

function After_Submit(e){
  var range = e.range;
  var row = range.getRow(); //get the row of newly added form data
  var sheet = range.getSheet(); //get the Sheet
  var headers = sheet.getRange(1, 1, 1, 129).getValues().flat(); //get the header names from A-O
  var data = sheet.getRange(row, 1, 1, headers.length).getValues(); //get the values of newly added form data + formulated values
  var values = {}; // create an object 
  for( var i = 0; i < headers.length; i++ ){
    values[headers[i]] = data[0][i]; //add elements to values object and use headers as key
  }

  Logger.log(values);
  const pdfFile = Create_PDF(values);
  sendEmail(e.namedValues['Email Address to Receive File '][0],pdfFile);
}

function sendEmail(email,pdfFile){
  
  GmailApp.sendEmail(email, "Subject", "Files Attached", {
    attachments: [pdfFile], 
    name: "From Email"

  });
 
}
function Create_PDF(values) {
  const PDF_folder = DriveApp.getFolderById("ID_1");
  const TEMP_FOLDER = DriveApp.getFolderById("ID_2");
  const PDF_Template = DriveApp.getFileById('ID_3');
  
  const newTempFile = PDF_Template.makeCopy(TEMP_FOLDER);
  const  OpenDoc = DocumentApp.openById(newTempFile.getId());
  const body = OpenDoc.getBody();
  
  console.log(body);

  body.replaceText("{{Timestamp}}", values['Timestamp'][0]);

Your question was how to loop through an object and replace text

This creates an object from Sheet0:

Sheet0:

one	pattern
two	this is the pattern
three	pattern pattern
four	nothing
five	nothing

Code:

function replacepattern() {
  const ss = SpreadsheetApp.getActive();
  const sh = ss.getSheetByName('Sheet0');
  const vs = sh.getRange(1,1,sh.getLastRow(), 2).getValues();
  //creating object from spreadsheet
  let obj = {pA:[]};
  vs.forEach(r =>{
    obj[r[0]]=r[1];
    obj.pA.push(r[0]);
  });
  Logger.log(JSON.stringify(obj));
  let oA = obj.pA.map(p => [obj[p].replace(/pattern/g,'replacement')]);//doing the replacement in an object
  sh.getRange(1,sh.getLastColumn() + 1,oA.length, oA[0].length).setValues(oA);//outputting the replaced string in the next column
  Logger.log(JSON.stringify(oA));
}

Sheet0 after running once:

one	pattern	replacement
two	this is the pattern	this is the replacement
three	pattern pattern	replacement replacement
four	nothing	nothing
five	nothing	nothing

Answer 2

This is related to my answer here .

The error code Exception: Invalid argument: replacement at Create_PDF(Code:37:8) at After_Submit(Code:13:19) is caused by the null value of values['Timestamp'][0] . If you try to print the data type of values['Timestamp'] , it will return a type object, since that object does not have value for index 0 to it will return a null value.

For entries that are type String, if you add [0] to it, it will return only the first element of the string. Example you have "Test" string, adding [0] to it will return "T"

To fix that, just remove the [0] in all of body.replaceText(..., values['...'][0]) entries.

OR

Loop through values object by replacing the body.replaceText entries in your code with this:

for (const key in values) {
   body.replaceText("{{"+key+"}}", values[key]);
}

Example usage:

Form inputs:
