javascript - 使用谷歌脚本自动将 CSV 输出到谷歌表格

Question

有人可以告诉我如何将导入的 CSV 数据附加到现有的 googlespreadsheet 中吗？导入后，底部有一个空行，每次运行代码时，我希望它从空的结束行开始插入新的 csv 数据。

谢谢

这是我现有的代码:

function getCSV() {
var fSource = DriveApp.getFolderById('0B2lVvlNIDosoajRRMUwySVBPNVE'); //    reports_folder_id = id of folder where csv reports are saved
var fi = fSource.getFilesByName('L661_BOM-CAD_14-12-15.csv'); // latest    report file
var ss  =SpreadsheetApp.openById('1WEDYfEudYsbkUhHbCxZspEbNXz3cjQIe3JdhnbFmmYA'); //    data_sheet_id = id of spreadsheet that holds the data to be updated with new     report data
var sd = SpreadsheetApp.getActiveSpreadsheet();
var s = SpreadsheetApp.getActiveSheet();
var target = new Array()
var sSheet = SpreadsheetApp.getActiveSpreadsheet();
sheet = SpreadsheetApp.setActiveSheet(sSheet.getSheets()[0]);

if ( fi.hasNext()) { // proceed if "report.csv" file exists in the reports    folder
var file = fi.next();
var csv = file.getBlob().getDataAsString();
var csvData = CSVToArray(csv); // see below for CSVToArray function
//sd.deleteSheet('newtest1')
  //var newsheet = ss.insertSheet('newtest11'); // create a 'NEWDATA' sheet   to store imported data
// loop through csv data array and insert (append) as rows into 'NEWDATA'   sheet

var sheet = ss.getSheets()[0];
 // Columns start at "1" - this will delete the first two columns
 //sheet.deleteColumns(6, 20);

 //var lastRow = sheet.getLastRow();sheet.appendRow(['']);
  //var lastRow = s.getLastRow();s.appendRow(['']);
  //s.deleteRows(lastRow+1, 50);

 s.getRange(+1, 1, csvData.length, csvData[5].length).setValues(csvData);



/*
** report data is now in 'NEWDATA' sheet in the spreadsheet - process it as needed,
** then delete 'NEWDATA' sheet using 
*/
// rename the report.csv file so it is not processed on next scheduled run

//file.setName("L661_BOM-CAD_14-12-15-"+(transferred)+".csv");
}
};

// This will parse a delimited string into an array of
// arrays. The default delimiter is the comma, but this
// can be overriden in the second argument.

function CSVToArray( strData, strDelimiter ){
    // Check to see if the delimiter is defined. If not,
    // then default to comma.
    strDelimiter = (strDelimiter || ";");

    // Create a regular expression to parse the CSV values.
    var objPattern = new RegExp(
        (
            // Delimiters.
            "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +

            // Quoted fields.
            "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +

            // Standard fields.
            "([^\"\\" + strDelimiter + "\\r\\n]*))"
        ),
        "gi"
        );


    // Create an array to hold our data. Give the array
    // a default empty first row.
    var arrData = [[]];

    // Create an array to hold our individual pattern
    // matching groups.
    var arrMatches = null;


    // Keep looping over the regular expression matches
    // until we can no longer find a match.
    while (arrMatches = objPattern.exec( strData )){

        // Get the delimiter that was found.
        var strMatchedDelimiter = arrMatches[ 1 ];

        // Check to see if the given delimiter has a length
        // (is not the start of string) and if it matches
        // field delimiter. If id does not, then we know
        // that this delimiter is a row delimiter.
        if (
            strMatchedDelimiter.length &&
            strMatchedDelimiter !== strDelimiter
            ){

            // Since we have reached a new row of data,
            // add an empty row to our data array.
            arrData.push( [] );

        }

        var strMatchedValue;

        // Now that we have our delimiter out of the way,
        // let's check to see which kind of value we
        // captured (quoted or unquoted).
        if (arrMatches[ 2 ]){

            // We found a quoted value. When we capture
            // this value, unescape any double quotes.
            strMatchedValue = arrMatches[ 2 ].replace(
                new RegExp( "\"\"", "g" ),
                "\""
                );

        } else {

            // We found a non-quoted value.
            strMatchedValue = arrMatches[ 3 ];

        }


        // Now that we have our value string, let's add
        // it to the data array.
        arrData[ arrData.length - 1 ].push( strMatchedValue );
    }

    // Return the parsed data.
    return( arrData );
}

这段代码:

for ( var i=0, lenCsv=csvData.length; i<lenCsv; i++ ) {
  newsheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new   Array(csvData[i]));
}

看起来它正在逐行写入数据。这比一次写入所有数据需要更多时间。首先将所有数据放入一个二维数组中，然后只写入一次数据。因此，不要在循环内使用 setValues()。在循环内构建一个数组，但不要在循环内写入数据。

var outerArray = [],
    innerArray = [];

for (var i=0, lenCsv=csvData.length; i<lenCsv; i++ ) {
  innerArray.push(new Array(csvData[i]));
  outerArray.push(innerArray);
};

newsheet.getRange(1, 1, outerArray.length, outerArray[0].length).setValues(outerArray));

上面的代码可能不起作用，但希望您能了解可以尝试的基本概念。

注意:如果数据行的长度不同，则会创建不同长度的内部数组。在这种情况下，就会发生错误。所有内部数组的长度必须完全相同。因此，如果您的数据具有不同长度的行，您需要通过插入空白值以某种方式使它们的长度相同，否则此策略将不起作用。
