使用Google Apps脚本将所有工作表转换为PDF

Question

我正在尝试将包含多个工作表的Google电子表格转换为PDF文件.下面的脚本有效,但它只使用电子表格的最后一页创建PDF.

function savePDFs() {
    SpreadsheetApp.flush();

    var ss = SpreadsheetApp.getActiveSpreadsheet();
    var sheets = ss.getSheets();
    var url = ss.getUrl();

    //remove the trailing 'edit' from the url
    url = url.replace(/edit$/,'');

    //additional parameters for exporting the sheet as a pdf
    var url_ext = 'export?exportFormat=pdf&format=pdf' + //export as pdf

    //below parameters are optional...
    '&size=letter' + //paper size
    '&portrait=false' + //orientation, false for landscape
    '&fitw=true' + //fit to width, false for actual size
    '&sheetnames=false&printtitle=false&pagenumbers=false' + //hide optional
    '&gridlines=false' + //false = hide gridlines
    '&fzr=false' + //do not repeat row headers (frozen rows) on each page
    '&gid='; //leave ID empty for now, this will be populated in the FOR loop

    var token = ScriptApp.getOAuthToken();

    //make an empty array to hold your fetched blobs
    var blobs = [];

    //.fetch is called for each sheet, the response is stored in var blobs[]
    for(var i = 0; i < sheets.length; i++) {
        var sheetname = sheets[i].getName();

        //if the sheet is one that you don't want to process,
        //continue' tells the for loop to skip this iteration of the loop
        if(sheetname == "Team Member Numbers")
            continue;

        //grab the blob for the sheet
        var response = UrlFetchApp.fetch(url + url_ext + sheets[i].getSheetId(), {
            headers: {
                'Authorization': 'Bearer ' +  token
            }
        });

        //convert the response to a blob and store in our array
        blobs.push(response.getBlob().setName(sheets[i].getName() + '.pdf'));
        var array_blob = response.getBlob().setName(sheets[i].getName() + '.pdf');
    }

    //from here you should be able to use and manipulate the blob to send and
    //email or create a file per usual.

    // send email
    var subject = "Enter Subject"
    var message = "See attached PDF"
    MailApp.sendEmail("email addy here", subject, message,{attachments:[array_blob]});
}

Answer 1

此功能是对此处“ianshedd...”提供的脚本的改编。

它：

• 生成电子表格中所有工作表的 PDF，并将它们存储在包含电子表格的同一文件夹中。（它假设只有一个文件夹这样做，尽管 Drive 确实允许多个容器。）

• 使用电子表格和工作表名称命名 pdf 文件。

• 使用 Drive 服务（不推荐使用 DocsList。）

• 可以使用可选的电子表格 ID 对任何工作表进行操作。默认情况下，它希望在包含脚本的“活动电子表格”上工作。

• 只需要“正常”授权即可操作；无需激活高级服务（好吧...您确实需要一些，请参阅此）或摆弄oAuthConfig.

  fetch()检索电子表格 PDF的调用的OAuth2 授权是通过 授予的ScriptApp.getOAuthToken()，这为我们提供了当前用户的 OAuth 2.0 访问令牌。

通过一些研究和努力，您可以连接到在线 PDF 合并 API，以生成单个 PDF 文件。除此之外，在 Google 提供一种将所有工作表导出为一个 PDF 的方法之前，您会被单独的文件困住。请参阅 Gilbert 的调整以获取获取多张纸的方法！

脚本：

/**

 * 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

Answer 2

我稍微调整了@Mogsdad代码,将整个电子表格打印为一个PDF.关键是调整导出参数.基本上更换

'&gid=' + sheet.getSheetId()   //the sheet's Id

同

(optSheetId ? ('&gid=' + sheet.getSheetId()) : ('&id=' + ss.getId()))  // Print either the entire Spreadsheet or the specified sheet if optSheetId is provided

所以上面的代码减去循环看起来像:

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 folder containing spreadsheet, for later export
  var parents = DriveApp.getFileById(ss.getId()).getParents();
  if (parents.hasNext()) {
    var folder = parents.next();
  }
  else {
    folder = DriveApp.getRootFolder();
  }

  //additional parameters for exporting the sheet as a pdf
  var url_ext = 'export?exportFormat=pdf&format=pdf'   //export as pdf

      // Print either the entire Spreadsheet or the specified sheet if optSheetId is provided
      + (optSheetId ? ('&gid=' + sheet.getSheetId()) : ('&id=' + ss.getId()))

      // 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("https://docs.google.com/spreadsheets/" + url_ext, options);
  var blob = response.getBlob().setName(ss.getName() + '.pdf');

  //from here you should be able to use and manipulate the blob to send and email or create a file per usual.
  //In this example, I save the pdf to drive
  folder.createFile(blob);

}

顺便说一句,谢谢 - 我一直在寻找这个解决方案很长一段时间!
