I have a .csv file with 3000 lines posted to a GDrive folded every morning, and I need to import data from that .csv into an existing Spreadsheet.
I had the following script that worked perfectly for a while, but it's been failing recently with the "Exception: Could not parse text." error. I triple-checked the .csv and confirmed the delimiter is correct.
function importOpps() {
var file = DriveApp.getFilesByName("Opportunity Report.csv").next();
var csvString = file.getBlob().getDataAsString()
var sanitizedString = csvString.replace(/(["'])(?:(?=(\\?))\2[\s\S])*?\1/g, function(e){return e.replace(/\r?\n|\r/g, ' ') });
Logger.log(sanitizedString)
var csvData = Utilities.parseCsv(sanitizedString);
var sheet = SpreadsheetApp.getActive().getSheetByName('opp');
sheet.getRange("A:AM").clear();
sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
}
I tried to find some workarounds and came across the following solution, which works for my case, but it takes forever to run.
function importData() {
var fSource = DriveApp.getFolderById('1Q3YU044I4g6SC3sRA37Gd3ezSJU5-O-i'); // reports_folder_id = id of folder where csv reports are saved
var fi = fSource.getFilesByName('SF Opportunity Report.csv'); // latest report file
var ss = SpreadsheetApp.openById('1E1RMG45Vtt0_gilDMnLTfWML_y4MSLqmH1dbCkL0UTM'); // data_sheet_id = id of spreadsheet that holds the data to be updated with new report data
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
var newsheet = ss.insertSheet('NEWDATA'); // create a 'NEWDATA' sheet to store imported data
// loop through csv data array and insert (append) as rows into 'NEWDATA' sheet
for ( var i=0, lenCsv=csvData.length; i<lenCsv; i ) {
newsheet.getRange(i 1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
/*
** report data is now in 'NEWDATA' sheet in the spreadsheet - process it as needed,
** then delete 'NEWDATA' sheet using ss.deleteSheet(newsheet)
*/
// rename the report.csv file so it is not processed on next scheduled run
file.setName("report-" (new Date().toString()) ".csv");
}
};
// http://www.bennadel.com/blog/1504-Ask-Ben-Parsing-CSV-Strings-With-Javascript-Exec-Regular-Expression-Command.htm
// 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 || "\t");
// 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 );
};
Any idea what can be wrong with the first script? In the .csv file, I have a field with users` comments so I assume that it may be that some special characters were used in that field breaking the parseCSV(). I am struggling to find the root cause of the issue. I am not good at code, so I would appreciate any help on this.
CodePudding user response：
I believe your goal is as follows.
- From
I have my .csv in the GDrive and not as a link., you want to retrieve the CSV data from a file and put to a Spreadsheet.
I thought that this sample script might be useful. But from your comment, I could know that you want to retrieve the CSV data from a file on Google Drive. This sample script retrieves the CSV data from a URL. For your situation, I modify this sample script for your situation. So this modified script can be used for the CSV data retrieved from Google Drive.
Sample script:
Before you use this script, please enable Sheets API at Advanced Google services. And please modify your script as follows.
From:
function importOpps() {
var file = DriveApp.getFilesByName("Opportunity Report.csv").next();
var csvString = file.getBlob().getDataAsString()
var sanitizedString = csvString.replace(/(["'])(?:(?=(\\?))\2[\s\S])*?\1/g, function(e){return e.replace(/\r?\n|\r/g, ' ') });
Logger.log(sanitizedString)
var csvData = Utilities.parseCsv(sanitizedString);
var sheet = SpreadsheetApp.getActive().getSheetByName('opp');
sheet.getRange("A:AM").clear();
sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
}
To:
function importOpps() {
var file = DriveApp.getFilesByName("Opportunity Report.csv").next();
var csvString = file.getBlob().getDataAsString();
var ss = SpreadsheetApp.getActive();
var sheet = ss.getSheetByName('opp');
sheet.getRange("A:AM").clear();
SpreadsheetApp.flush();
var req = { pasteData: { data: csvString, delimiter: ",", coordinate: { sheetId: sheet.getSheetId() } } };
Sheets.Spreadsheets.batchUpdate({requests: [req]}, ss.getId());
}
- When your CSV data uses the specific delimiter, please set
delimiter: ",".
