Importing csv file to google sheets using script - google-apps-script

Question

i am faced with the below problem. I am going to be presented with a .csv file that will contain the following fields:
ItemID Date Source name Title URL Created ItemSourceType
However i won't need all of the fields but i will need to import this into a pre-defined google sheets template, which looks like the below:
Date Writer Status Geog/Area/Product Source Title Note
Again not all of the columns will need to be populated, and so the final solution should look like this.
Date Writer Status Geog/Area/Product Source Title Note
Today() NULL NULL Null Site Title-(hyperlinked with URL) Null
i have put together the following code - some of this has been testing and trying to split out a CSV, and i've not yet attempted to add the hyperlinked field.
function addData() {
var fSource = DriveApp.getFolderById('138ZRbesgDkKHOROm4izD22oaXoanvsyJ'); // reports_folder_id = id of folder where csv reports are saved
var sheet = SpreadsheetApp.getActiveSheet();
var startRow = 12; // First row of data to process
var numRows = 2; // Number of rows to process
var fSource = DriveApp.getFolderById('138ZRbesgDkKHOROm4izD22oaXoanvsyJ'); // reports_folder_id = id of folder where csv reports are saved
var fi = fSource.getFilesByName('data.csv'); // latest report file
var ss = SpreadsheetApp.openById('1wBawJzQ3eAhyjCuetAFg7uUUrum6CDImBcVcxaZ9j84'); // 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);
for ( var i=1, lenCsv=csvData.length; i<lenCsv; i++ ) {
sheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
}
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 );
};
// Fetch the range of cells A2:G3
var dataRange = sheet.getRange(startRow, 1, numRows,8)//sheet.getRange(startRow, 1, numRows, 8)
var data = dataRange.getValues();
for (var i = 0; i < data.length; ++i) {
var row = data[i];
var ItemID = row[0]
var Date = row[1]
var SourceName = row[2]
var Title = row[3]
var URL = row[4]
var Created = row[5]
var ItemSourceType = row[6]
sheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
var correctFormat = ItemID + ", " + Date + ", " + SourceName + ", " + Title + ", " + URL + ", " + Created + ", " + ItemSourceType;
Logger.log(correctFormat)
}
If anyone is able to help point me in the right direction it would be greatly appreciated.
The part of this that i am struggling with is using the Array to populate the spreadsheet with the fields in the correct order, I have put the array below.
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 );
};

It seems like this site (https://ctrlq.org/code/20279-import-csv-into-google-spreadsheet) does include several ways to import a CSV into a google spreadsheet.
For instance for importing from google drive you can do:
function importCSVFromGoogleDrive() {
var file = DriveApp.getFilesByName("data.csv").next();
var csvData = Utilities.parseCsv(file.getBlob().getDataAsString());
var sheet = SpreadsheetApp.getActiveSheet();
sheet.getRange(1, 1, csvData.length, csvData[0].length).setValues(csvData);
}
After that you will need to filter the data you want, but i guess it is easier to do that once you have imported the data from the csv.
