Trying to create tree-view of google drive folders - google-apps-script

Question

Many thanks for the comments and response. That code was a little too advanced for me and I ended up finding a very inelegant solution that I used because I ran out of time. I was able to get the code to list Folder and first level of subFolders with links, but I have not yet been able to get it to iterate through all levels of folders, mostly because I just need to back up and learn a lot of the basics. I was also able to get all folders to list using some code I found to create a tree, but I couldn't get it to format in a way that you could actually see the structure, or add links. I'm going to continue to try, and will post if I sort it out. Here is what I used, which was fine for our purposes because our shared drive is fairly limited.
For reference, this was the code I used to start with:
https://superuser.com/questions/1095578/list-of-subfolder-names-and-file-links-in-google-sheets-script
function listFolders(foldername) {
var ss = SpreadsheetApp.openById(ID);
var sheet = ss.getSheetByName("sheet name");
sheet.appendRow("Parent Folder", "Name", "Link" ]);
//change the folder ID below to reflect your folder's ID (look in the
URL when you're in your folder)
var folders = DriveApp.getFolderById(ID);
var contents = folders.getFolders();
var cnt = 0;
var folderD;
while (contents.hasNext()) {
var folderD = contents.next();
cnt++;
data = [
folders.getName(),
folderD.getName(),
folderD.getUrl(),
];
sheet.appendRow(data);
};
};
Original Post:
I am a beginner using script in google sheets and I am trying to create a list of folders in a google drive with many subfolders. Ideally it would be a tree form but I'd settle for a list at this point. I don't need to list all the files, just the folders. I have been trying to get the code below to work but it keeps hanging up at calling up the spreadsheet. Can anyone help?
I have tried calling up both the folders and the spreadsheet by both name and ID but it always tells me it can't execute the getactivespreadsheet command. I have also tried to modify the code referred to in another another question but I can't get that to work either: https://ctrlq.org/code/19923-google-drive-files-list
function generateFolderIndex(myfoldername) {
var folder = DriveApp.getFolderById('0B8vOJQUb-IIVTHdudlZSVkdtdE0');
var subFolders = folder.getFolders();
var childFolders = subFolders
var ss = SpreadsheetApp.getActiveSpreadsheet('1Trv9OtJFnD4AdSHrZKFfsSu6JMV9f78H6wwZNhF2_M4');
var sheet = ss.getSheetByName('Directory');
sheet.clear(directory);
sheet.appendRow([name, link]);
while (subFolders.hasNext())
{
var childFolder = childFolders.next();
var foldername = childFolder.getname();
var name = childFolder.getName()
var link = childFolder.getUrl()
var date = childFolder.getDateCreated()
data = [name, link]
sheet.appendRow(data);
}
};
I am trying to get a sheet that lists folders and subfolders with URL links. I am currently receiving the following error message:
[19-05-31 15:32:20:911 EDT] Execution failed: Cannot find method getActiveSpreadsheet(string). (line 5, file "Code") [0.432 seconds total runtime]

Answer 1

Or.. the easy way...
Use DRIVE or FS DRIVE APP for desktop in PC. Usea A CMD (windows)... AND THE FUNCTION
TREE >a.txt
The generated file a.txt will display all the tree.
IT SAVES HOURS OF RESEARCH.

Answer 2

SpreadsheetApp.getActiveSpreadsheet() doesn't have any parameters.
However
SpreadsheetApp.openById('ssid') does require and id. I think perhaps you meant to be using openById();
openById
getActiveSpreadsheet
This is a script that I'm currently working on but it generates a list of Spreadsheets and you can exclude folders by id and files by id.
function getAllSpreadsheets() {
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('FilesAndFolders');
if(sh.getLastRow()>0) {
sh.getRange(1,1,sh.getLastRow(),2).clear().clearDataValidations();
}
getFnF();
SpreadsheetApp.getUi().alert('Process Complete')
}
var level=0;
function getFnF(folder) {
var folder= folder || DriveApp.getRootFolder();
//var folder=DriveApp.getRootFolder();
var ss=SpreadsheetApp.getActive();
var sh=ss.getSheetByName('FilesAndFolders');
var files=folder.getFilesByType(MimeType.GOOGLE_SHEETS)
while(files.hasNext()) {
var file=files.next();
if(isExcluded(file.getId(),'file')){continue;}
var firg=sh.getRange(sh.getLastRow() + 1,level + 1);
firg.setValue(Utilities.formatString('=HYPERLINK("%s","%s")',file.getUrl(),'FILE: ' + file.getName()));
firg.offset(0,1).insertCheckboxes('Exclude','Include');
}
var subfolders=folder.getFolders()
while(subfolders.hasNext()) {
var subfolder=subfolders.next();
if(isExcluded(subfolder.getId(),'folder')){continue;}
var forg=sh.getRange(sh.getLastRow() + 1,level + 1);
forg.setValue(Utilities.formatString('=HYPERLINK("%s","%s")',subfolder.getUrl(),'FOLDER: ' + subfolder.getName()));
//forg.offset(0,1).insertCheckboxes('Exclude','Include');
//level++;
getFnF(subfolder);
}
//level--;
}
function isExcluded(id,type) {//type: file or folder
var type=type||'Missing Input';
var xFldrIdA=['Excluded folder ids'];
var xFileIdA=['Excluded file ids'];
var type=type.toLowerCase();
switch(type) {
case 'file':
return xFileIdA.indexOf(id)>-1;
break;
case 'folder':
return xFldrIdA.indexOf(id)>-1;
break;
default:
throw(Utilities.formatString('Error: Invalid Type: %s in isExcluded.',type));
return true;//assume excluded
break;
}
}
Your welcome to use it, perhaps it will help.
