Convert all sheets to PDF with Google Apps Script

Question

I\'m trying to convert a Google spreadsheet with multiple sheets to a PDF file. The script below works, but it only creates a PDF with the last page of the spreadsheet.

Answer 1

Here's my variation on this theme, based on Dr Queso's answer.

All parameters (described in the code) are optional and if none are specified it uses the active spreadsheet, converts all of the tabs into a single PDF named after the spreadsheet and doesn't email the PDF.

function test() {

  // Create a PDF containing all the tabs in the active spreadsheet, name it
  // after the spreadsheet, and email it
  convertSpreadsheetToPdf('user@email.com')

  // Create a PDF containing all the tabs in the spreadsheet specified, name it
  // after the spreadsheet, and email it
  convertSpreadsheetToPdf('user@email.com', '1r9INcnsyvSQmeduJWVYAvznOOYei9jeAjsy0acA3G1k')

  // Create a PDF just containing the tab 'Sheet2' in the active spreadsheet, specify a name, and email it
  convertSpreadsheetToPdf('user@email.com', null, 'Sheet2', 'PDF 3')
}

/*
 * Save spreadsheet as a PDF
 *     
 * @param {String} email Where to send the PDF [OPTIONAL] 
 * @param {String} spreadsheetId Or the active spreadsheet[OPTIONAL]
 * @param {String} sheetName The tab to output [OPTIONAL]
 * @param {String} PdfName [OPTIONAL]
 */

function convertSpreadsheetToPdf(email, spreadsheetId, sheetName, pdfName) {

  var spreadsheet = spreadsheetId ? SpreadsheetApp.openById(spreadsheetId) : SpreadsheetApp.getActiveSpreadsheet();
  spreadsheetId = spreadsheetId ? spreadsheetId : spreadsheet.getId()  
  var sheetId = sheetName ? spreadsheet.getSheetByName(sheetName).getSheetId() : null;  
  var pdfName = pdfName ? pdfName : spreadsheet.getName();
  var parents = DriveApp.getFileById(spreadsheetId).getParents();
  var folder = parents.hasNext() ? parents.next() : DriveApp.getRootFolder();
  var url_base = spreadsheet.getUrl().replace(/edit$/,'');

  var url_ext = 'export?exportFormat=pdf&format=pdf'   //export as pdf

      // Print either the entire Spreadsheet or the specified sheet if optSheetId is provided
      + (sheetId ? ('&gid=' + sheetId) : ('&id=' + spreadsheetId)) 
      // following parameters are optional...
      + '&size=letter'      // paper size
      + '&portrait=true'    // orientation, false for landscape
      + '&fitw=true'        // fit to width, false for actual size
      + '&sheetnames=false&printtitle=false&pagenumbers=false'  //hide optional headers and footers
      + '&gridlines=false'  // hide gridlines
      + '&fzr=false';       // do not repeat row headers (frozen rows) on each page

  var options = {
    headers: {
      'Authorization': 'Bearer ' +  ScriptApp.getOAuthToken(),
    }
  }

  var response = UrlFetchApp.fetch(url_base + url_ext, options);
  var blob = response.getBlob().setName(pdfName + '.pdf');
  folder.createFile(blob);

  if (email) {

    var mailOptions = {
      attachments:blob
    }

    MailApp.sendEmail(
      email, 
      "Here is a file named " + pdfName, 
      "Please let me know if you have any questions or comments.", 
      mailOptions);
  }

} // convertSpreadsheetToPdf()

NOTE: This doesn't work if the sheet is hidden. Use activate() to unhide a sheet.
