Sheets Scripts- Save As PDF- Pull File Name from Cell

Question

Objective: Automatically insert file name for Download as PDF.

I have put together a script that opens a print preview screen that allows me to print the selected cells. It also has a download button that allows me to download the preview as a PDF. I would like to be able to set the file name from the combination of 3 cells. Name ('C6:J6') + Date('L54:N54') + Time ('S54:U54'). These cells are all on the same sheet that is being printed. I am at a loss as to how to do this.

Below is my script and a screenshot of my print preview screen. Circled is the file name that I would like to replace and the download button that opens the standard download file screen. Thank you in advance!

You need to download the file using UrlFetchApp.fetch() , create a file based on the response for the fetch() using DriveApp.createFile() , rename it, get the URL of newly created file and set it as value of htmlTemplate.url .

Replace the printSelectedRange() in your code with this:

function printSelectedRange() {
  SpreadsheetApp.flush();
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  var sheet = ss.getActiveSheet();
  var range = sheet.getActiveRange();
 

  var gid = sheet.getSheetId();
  var printRange = objectToQueryString({
    'c1': range.getColumn() - 1,
    'r1': range.getRow() - 1,
    'c2': range.getColumn() + range.getWidth() - 1,
    'r2': range.getRow() + range.getHeight() - 1
  });
  var url = ss.getUrl().replace(/edit$/, '') + 'export?format=pdf' + PDF_OPTS + printRange + "&gid=" + gid;

  var params = {method:"GET",headers:{"authorization":"Bearer "+ ScriptApp.getOAuthToken()}};
  
  var response = UrlFetchApp.fetch(url, params).getBlob();

  var name = sheet.getRange('C6:J6').getDisplayValue();
  var date = sheet.getRange('L54:N54').getDisplayValue();
  var time = sheet.getRange('S54:U54').getDisplayValue();
  var filename = name + "-" +  date + "-" + time;

  //create new file on drive
  var newFile = DriveApp.createFile(response).setName(filename);
  
  var htmlTemplate = HtmlService.createTemplateFromFile('js');
  htmlTemplate.url = newFile.getUrl();
  SpreadsheetApp.getUi().showModalDialog(htmlTemplate.evaluate().setHeight(10).setWidth(100), 'Print range');
}

Example Output:

Note: If you want to remove the generated file after you print it, you can add newFile.setTrashed(true); at the end of printSelectedRange() function. This will move the files to trash. Files in trash will be automatically deleted after 30 days.

• UrlFetchApp.fetch()
