Google apps script to get results in spreadsheet - google-apps-script

Question

I am new to Google App Scripts and am trying to modify this script to return the results to a spreadsheet instead of the logger.
function myFunction() {
const getFileList = (id, folders = []) => {
const f = DriveApp.getFolderById(id);
const fols = f.getFolders();
let temp = [];
while (fols.hasNext()) {
const fol = fols.next();
const files = fol.getFiles();
let fileList = [];
while (files.hasNext()) {
const file = files.next();
fileList.push({ name: file.getName(), id: file.getId() });
}
temp.push({
name: fol.getName(),
id: fol.getId(),
parent: id,
parentName: f.getName(),
files: fileList,
});
}
if (temp.length > 0) {
folders.push(temp);
temp.forEach((e) => getFileList(e.id, folders));
}
return folders;
};
const folderId = "###"; // Folder ID of the shared Drive.
const res = getFileList(folderId);
console.log(res);
}

Answer 1

I believe your goal as follows.
You want to put the values from getFileList(folderId) to the Spreadsheet.
The value returned from getFileList(folderId) is the array including JSON object. So, in this case, it is required to convert from JSON object to an array for each element. For this, I also think that Carlos M's comment is useful. But, for this, it is required to modify a little for putting values to Spreadsheet. Because the value from getFileList(folderId) is 2 dimensional array and each file in the subfolders is also included in an array. In this answer, I would like to propose the modified script for putting values to Spreadsheet.
When your script is modified, please modify as follows.
Modified script:
From:
const folderId = "###"; // Folder ID of the shared Drive.
const res = getFileList(folderId);
console.log(res);
To:
const folderId = "###"; // Folder ID of the shared Drive.
const res = getFileList(folderId);
console.log(res);
// I added below script.
const object = res.flat();
const headers = Object.keys(object[0]);
const values = object.flatMap(o => {
const temp = [];
headers.forEach(f => {
if (f != "files") temp.push(o[f]);
});
return o.files.map(({name, id}) => temp.concat(name, id));
});
headers.pop();
headers.push("file(name)", "file(id)");
values.unshift(headers);
SpreadsheetApp.getActiveSheet().getRange(1, 1, values.length, values[0].length).setValues(values);
When you run this modified script, the retrieved values are put to the active sheet.
