谷歌企业应用套件 Gmail CSV 导入到工作表错误

Question

我从各种谷歌搜索中拼凑了这段代码，如果电子邮件具有特定的标签，这些代码将提取电子邮件的CSV附件。

function importCSVFromGmail() { 
//gets first(latest) message with set label
var threads = GmailApp.getUserLabelByName('Dashboard Updates').getThreads(0,1);     
var message = threads[0].getMessages()[0];
var attachment = message.getAttachments()[0];
// Is the attachment a CSV file
if (attachment.getContentType() === "text/csv") {                            
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("Monthly_Detail_Instantis");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var escapedString = dataString.replace(/(?=["'])(?:"[^"\]*(?:\[sS][^"\]*)*"|'[^'\]rn(?:\[sS][^'\]rn)*')/g, '\r\n');
var csvData = Utilities.parseCsv(escapedString);
// Remember to clear the content of the sheet before importing new data
sh.clearContents().clearFormats();                                         
//pastes array to sheet
sh.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);   
}
//marks the Gmail message as read and unstars it (Filter sets a star)
message.markRead();                                                          
message.unstar();                                                            
}

该脚本运行良好，但是我遇到了带有逗号或引号值的单元格的问题。例如，如果单元格具有以下内容：

1,000,000

或

Google "Apps" Script

它将分别返回到以下内容。

rn
rnrnrn

我确定这与所使用的正则表达式有关，但我不确定如何针对上述内容进行调整。任何这方面的帮助将不胜感激。

我能够使用原始代码(在有问题中使用(并将转义和 Utilities.parseCsv 替换为此链接中的代码。这将正确导入 CSV，即使单元格包含引号和逗号： https://productforums.google.com/forum/#!topic/docs/nhXjrl8JIek

这是我的最终代码：

function importCSVFromGmail() { 
//gets first(latest) message with set label
var threads = GmailApp.getUserLabelByName('Dashboard Updates').getThreads(0,1);     
var message = threads[0].getMessages()[0];
var attachment = message.getAttachments()[0];
// Is the attachment a CSV file
if (attachment.getContentType() === "text/csv") {                            
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("Monthly_Detail_Instantis");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var csvData = CSVToArray(dataString);
// Remember to clear the content of the sheet before importing new data
sh.clearContents().clearFormats();                                         
//pastes array to sheet
var lastRowValue = sh.getLastRow();
for (var i = 0; i < csvData.length; i++) {
sh.getRange(i+lastRowValue+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
} 
}
//marks the Gmail message as read and unstars it (Filter sets a star)
message.markRead();                                                          
message.unstar();                                                            
}
//The code formats the code so it can be entered into the Google Script
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( [] );
}
// 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.
var strMatchedValue = arrMatches[ 2 ].replace(
new RegExp( """", "g" ),
"""
);
} else {
// We found a non-quoted value.
var 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 );
