合併多個選項卡，以CSV格式下載

Question

我在Google文件夾中放置了一打工作表。通過下面的腳本，我可以將每個文件的第一個選項卡複製到新的電子表格中。 但是現在我希望所有的數據只需在一個選項卡中複製，並將其作爲csv文件下載到共享驅動器（而不是谷歌應用程序）。數據的格式總是相同的，有時每行的行數不同。

此外，我想選擇基於名稱而不是數字的選項卡 - 以避免將來發生錯誤。任何建議如何解決這個問題？

function mergeSheets() { 

/* Retrieve the desired folder */ 
var myFolder = DriveApp.getFoldersByName('name of folder').next(); 

/* Get all spreadsheets that resided on that folder */ 
var spreadSheets = myFolder.getFilesByType("application/vnd.google- apps.spreadsheet"); 

/* Create the new spreadsheet that you store other sheets */ 
var newSpreadSheet = SpreadsheetApp.create("Merged Sheets"); 

/* Iterate over the spreadsheets over the folder */ 
while(spreadSheets.hasNext()) { 

var sheet = spreadSheets.next(); 

/* Open the spreadsheet */ 
var spreadSheet = SpreadsheetApp.openById(sheet.getId()); 

/* Get all its sheets */ 
// for(var y in spreadSheet.getSheets()) { 

    /* Copy the sheet to the new merged Spread Sheet */ 
    spreadSheet.getSheets()[0].copyTo(newSpreadSheet); 
// } 
}  
} 

Answer 1

下面是使用更快速的方法將文件夾中的所有電子表格編譯成單個電子表格表單的另一種可能解決方案（concatenate arrays）。

唯一的限制是，所有的表必須有相同數量的列（行號並不重要）

從這個單張它會很容易對其contnet導出爲CSV並將其保存爲一個驅動器文件。 我用你的代碼作爲起點，並評論那些迭代每個電子表格中所有表單的部分，就像你做的一樣，但是你當然可以取消註釋for循環）。 我添加了一些註釋來解釋過程。

function mergeSheets() { 
    /* Retrieve the desired folder */ 
    //var myFolder = DriveApp.getFoldersByName('name of folder').next(); 
    // or better 
    var myFolder = DriveApp.getFolderById('0B3qSFd3iikE3RDhxekVYNk5zUkk'); 

    /* Get all spreadsheets that resided on that folder */ 
    var spreadSheets = myFolder.getFilesByType(MimeType.GOOGLE_SHEETS); 

    /* Create the new spreadsheet that you store other sheets */ 
    var newSpreadSheet = SpreadsheetApp.create("Merged Sheets"); 
    var newSheetTab = newSpreadSheet.getActiveSheet(); 
    var values = [] ;// new array to get all sheets contents 
    /* Iterate over the spreadsheets over the folder */ 
    var header = []; 
    while(spreadSheets.hasNext()) { 

    var sheet = spreadSheets.next(); 
    Logger.log(sheet.getName()); // log the sheet name to check 
    /* Open the spreadsheet */ 
    var spreadSheet = SpreadsheetApp.openById(sheet.getId()); 

    /* Get all its sheets */ 
    // for(var y in spreadSheet.getSheets()) { 

    //for(var sheet in spreadSheet.getSheets()){ 
     var sheet = spreadSheet.getSheets()[0];// comment this line if you keep the for loop 
     var range = sheet.getDataRange(); 
     var data = range.getValues(); 
     if(header.length==0){ 
     header = data.shift(); // get the header only once and remove header from data in the same time 
     }else{ 
     var dummy = data.shift(); // remove header from data but don't keep it 
     } 
     values = values.concat(data); // add data to final array in each while loop 
    // } 
    } 
    values.unshift(header); // add the header at the array start 
    Logger.log(values);//see result 
    newSheetTab.getRange(1,1,values.length, values[0].length).setValues(values);// batch write to the sheet 
} 

// then export this single sheet as CSV see code from Google tuto

function mergeSheets() { 

/* Retrieve the desired folder */ 
var myFolder = DriveApp.getFoldersByName('name of folder').next(); 

/* Get all spreadsheets that resided on that folder */ 
var spreadSheets = myFolder.getFilesByType("application/vnd.google- apps.spreadsheet"); 

/* Create the new spreadsheet that you store other sheets */ 
var newSpreadSheet = SpreadsheetApp.create("Merged Sheets"); 
var newSheetTab = newSpreadSheet.getActiveSheet(); 

/* Iterate over the spreadsheets over the folder */ 
while(spreadSheets.hasNext()) { 

var sheet = spreadSheets.next(); 

/* Open the spreadsheet */ 
var spreadSheet = SpreadsheetApp.openById(sheet.getId()); 

/* Get all its sheets */ 
// for(var y in spreadSheet.getSheets()) { 

    /* Copy the sheet to the new merged Spread Sheet */ 
    var range = spreadSheet.getSheetByName('sheet name').getDataRange(); 

    // start after header row 
    // may have to adjust these upon desired effect 
    for (var i = 1; i < range.getNumRows(); i++) 
    { 
     newSheetTab.appendRow(range[i]); 
    } 

// } 
} 

// then save as csv 
}
