So I'm using this script to create csv files for graph data variables for Adobe Illustrator. My problem is that my first column of data is a number and needs to wrapped in double quotes like "2016", otherwise Illustrator renders 2016 as a data value in the chart.

When I manually download sheet to CSV, I do get the quotes, But when I run the script they are stripped out.

In order to get the quotes to appear in the manual download I had to do it by formula " =CONCATENATE(CHAR(34),"2015",CHAR(34))"

Please help, if I can get this to work it will cut out a ton of production time for me.

Instead of creating a new folder / new file every time, could I use this to update an existing file in the same folder?

Hi All,
How do I modify this to run every 24 hours and export to the same folder, but only a particular sheet (file), not all ActiveSheets?
Thanks,
Jon

Got this script to save the csv file in the same folder by adding this line:
var folderX = DriveApp.getFolderById('dir_id');
Where you have to change the input the desired folder ID.

And, lastly,modifying this one:
folder.createFile(fileName, csvFile);
To
folderX.createFile(fileName, csvFile);

How can we use this code to export all sheets of a google spreadsheet by using drive/sheet api. By using the below mentioned code I can only download the first sheet from spreadsheet and I want to download all the sheets available inside my spreadsheet. My code is given below.

function downloadGDriveFile (file) {
var request1 = gapi.client.drive.files.export({
'fileId': '1VLFgD8CNvXTVdHKyBdZPUmgFmhWMzg7qWLbxzLUTtSo',
//The id to second sheet is gid=156482034',
'mimeType': 'text/csv'
})
request1.then(function(response) {
console.log(response);
alert(response.body);
$.ajax({
type: "POST",
url: 'http://pathToFile/scripts/ravin/last/interfacefile.php',
data: {data : response.body},
success: function(response) {
}
});
//-----------------
}, function(err) {
console.log('Error');
console.log(err.result.error);
});
}

Hello Michael,

thank you for the script - it works perfectly! I was wondering, if it is possible to alter it somehow so it would be able to export files in .tsv format instead of .csv? I tried to replace the comma character on lines 203 and 211 with space, but I need tabs instead of spaces. Do you know about any solution, please?

Thanks,
Martin

@martinneuschl: Just use "\t" instead of ","

Instead of creating a new folder / new file every time, could I use this to update an existing file in the same folder?

@cgrouge: Yes, you can. Just use this function:

function writeFile(folder, fileName, data) {
  var existingFiles = folder.getFilesByName(fileName);
  if (existingFiles.hasNext()) {
    existingFiles.next().setContent(data);
  } else {
    folder.createFile(fileName, data, 'text/csv');
  }
}

Hi, this is being very helpful, but is there a way to DOWNLOAD the CSVs instead of creating a folder in Drive?

I need them to upload the files in another place, so having to download them from gdrive is adding 1 more step

@EdusanSanta: You can do that directly from the Google Sheets UI:

File > Download > Comma-separated values (.csv, current sheet)

Yes, but i have many sheets and that option only exports the active sheet.

The script Will convert all My sheets into csv, but would be great if after that it downloads them.

Is it possible?

@EdusanSanta: There's a way, but it's not as straightforward as you might like:

  • Browsers require the user to perform an action (i.e. click) to initiate a download - you can't "push" a download to the user. App Scripts don't have any special way to achieve this either.
  • If you want to download multiple files (csv files cannot contain multiple sheets/tabs), this means one click per file.
  • Downloads are usually done through the use of download links (MDN doc here - see "download" attribute), using either data urls, object urls, or traditional links pointing to a file on a server.
  • Data urls can have size limitations in some browsers, so use with caution. The data also needs to be encoded - either url encoded, or base64 encoded.
  • In general, object urls are preferred - but I don't think the API is available in app scripts.

Here are some resources if you'd like to learn more:

Here's how I would implement your download of all sheets:

  • Use app scripts to build a custom popup/dialog with a downloadable link for each sheet.
  • I would hijack the functionality already offered by Google Docs, and build links that point to the File > Download > CSV url for each sheet.
  • Here's what the urls looks like: https://docs.google.com/spreadsheets/d/[DOCUMENT_ID]/export?format=csv&id=[DOCUMENT_ID]&gid=[SHEET_ID]
  • You can get the DOCUMENT_ID via SpreadsheetApp.getActiveSpreadsheet().getId()
  • You can get the SHEET_ID for each sheet via Sheet.getSheetId()

@mderazon thanks a lot for sharing this.
Could you be having a snippet code that can convert an individual sheet to a downloadable excel(xlsx) file.
I have tried the following code but the issue is, its downloading all sheets instead of an individual sheet.
function makeXlsx() { var sheetId = "1x53K43fytf55k4D0WqWckKCpX_1w0098-a8HM"; var url = "https://docs.google.com/spreadsheets/d/" + sheetId + "/export?format=xlsx&access_token=" + ScriptApp.getOAuthToken(); var blob = UrlFetchApp.fetch(url).getBlob().setName(name + ".xlsx"); folder.createFile(blob); }

Hi
I'm using this code to save a whole lot of bank account details to a CSV file, but some bank accounts start with a zero and when the account number is saved to the csv file, the leading zero is dropped. Please can someone suggest a edit that will solve this.

Thanks
