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

This function is an adaptation of a script provided by "ianshedd..." here.

It:

• Generates PDFs of ALL sheets in a spreadsheet, and stores them in the same folder containing the spreadsheet. (It assumes there's just one folder doing that, although Drive does allow multiple containment.)

• Names pdf files with Spreadsheet & Sheet names.

• Uses the Drive service (DocsList is deprecated.)

• Can use an optional Spreadsheet ID to operate on any sheet. By default, it expects to work on the "active spreadsheet" containing the script.

• Needs only "normal" authorization to operate; no need to activate advanced services (well... you do need some, see this) or fiddle with oAuthConfig.

  OAuth2 Authorization for the fetch() call that retrieves the PDF of a spreadsheet is granted via ScriptApp.getOAuthToken(), which gives us the OAuth 2.0 access token for the current user.

With a bit of research and effort, you could hook up to an online PDF Merge API, to generate a single PDF file. Barring that, and until Google provides a way to export all sheets in one PDF, you're stuck with separate files. See Gilbert's tweak for a way to get multiple sheets!

Script:

/**
 * Export one or all sheets in a spreadsheet as PDF files on user's Google Drive,
 * in same folder that contained original spreadsheet.
 *
 * Adapted from https://code.google.com/p/google-apps-script-issues/issues/detail?id=3579#c25
 *
 * @param {String}  optSSId       (optional) ID of spreadsheet to export.
 *                                If not provided, script assumes it is
 *                                sheet-bound and opens the active spreadsheet.
 * @param {String}  optSheetId    (optional) ID of single sheet to export.
 *                                If not provided, all sheets will export.

function savePDFs( optSSId, optSheetId ) {

  // If a sheet ID was provided, open that sheet, otherwise assume script is
  // sheet-bound, and open the active spreadsheet.
  var ss = (optSSId) ? SpreadsheetApp.openById(optSSId) : SpreadsheetApp.getActiveSpreadsheet();
  
  // Get URL of spreadsheet, and remove the trailing 'edit'
  var url = ss.getUrl().replace(/edit$/,'');

  // Get folder containing spreadsheet, for later export
  var parents = DriveApp.getFileById(ss.getId()).getParents();
  if (parents.hasNext()) {
    var folder = parents.next();
  }
  else {
    folder = DriveApp.getRootFolder();
  }
  
  // Get array of all sheets in spreadsheet
  var sheets = ss.getSheets();
  
  // Loop through all sheets, generating PDF files.
