Google Apps Script: how to copy array of objects to range?

I have an array of objects called membership:

[{name: 'Linus Pauling', address: '1805 Main Street', phone: '(615) 555-1010', 
  email: '[email protected]' },

 {name: 'Maury Povich', address: '382 North Street', phone: '(423) 555-1997', 
  email: '[email protected]'}]

(Although only 4 are shown here, I really have ten key/value pairs per member.)

What is the best way to copy bits of this array to a range of cells in Google Sheets? I am trying to find a method to call the object values directly, and use the .SetValues method to copy them en masse, as opposed to one at a time.

To get all the members' names in column A, I've tried:

sheet.getRange(1,1,membership.length,1).setValues(membership[{member.name}]);

...which gives Missing : after property ID.

Or:

sheet.getRange(1,1,membership.length,1).setValues([membership[name]]);

...which gives ReferenceError: "name" is not defined.

Or:

sheet.getRange(1,1,membership.length,1).setValues([member.name]);

...which gives the "Cannot convert Array to Object[][]" error.

I apologize for the newbie question. I have seen answers about how to copy values from a multidimensional array to a sheet's range, but not an array of objects.

See the script at the bottom of the Simple Mail Merge Tutorial for some useful code to retrieve data. Copy all the code from this comment down:

//////////////////////////////////////////////////////////////////////////////////////////
//
// The code below is reused from the 'Reading Spreadsheet data using JavaScript Objects'
// tutorial.
//
/////////

/////////////////////////////////////////////////////////////////////////////////

// getRowsData iterates row by row in the input range and returns an array of objects.

Once you have, the getRowsData returns not only the data, but a second item which is a list of the Headers. Using this, you can modfy the code from @Bardy to allow for the Headers in any order, and also other possible columns in between.

Are you looking to produce a table in the form:

name | Address | phone | email
-----+---------+-------+------
.... | ....    | ....  | ....

etc?

If so, then the following snippet may help. The key thing to point out here is that you can't expect a given order when iterating through an object. i.e. Just because your representation of membership lists name first, doesn't mean that if you were to use a for ... in loop you could guarantee that name would come back first - Objects in JavaScript are unordered.

To ensure a given order, the snippet I list defines an array headings in which you specify the order of the columns you want in the Sheet. This is used to guarantee the column order in the output:

var membership = [
  {
    name: 'Linus Pauling', address: '1805 Main Street', phone: '(615) 555-1010', 
    email: '[email protected]'
  },
  {
    name: 'Maury Povich', address: '382 North Street', phone: '(423) 555-1997', 
    email: '[email protected]'
  }
];

// Headings in the column order that you wish the table to appear.
var headings = ['name', 'address', 'phone', 'email'];
var outputRows = [];

// Loop through each member
membership.forEach(function(member) {
  // Add a new row to the output mapping each header to the corresponding member value.
  outputRows.push(headings.map(function(heading) {
    return member[heading] || '';
  }));
});

// Write to sheets
if (outputRows.length) {
  // Add the headings - delete this next line if headings not required
  outputRows.unshift(headings);
  SpreadsheetApp.getActiveSheet().getRange(1, 1, outputRows.length, outputRows[0].length).setValues(outputRows);
}

Output is :

How about following script? This script is a container bound script of spreadsheet. There are 2 patterns. The arrangement of data is different for between pattern 1 and 2.

Pattern 1 is enter image description here

Pattern 2 is enter image description here

function main() {
  var data = [{name: 'Linus Pauling', address: '1805 Main Street', phone: '(615) 555-1010', 
  email: '[email protected]' }, {name: 'Maury Povich', address: '382 North Street', phone: '(423) 555-1997', 
    email: '[email protected]'}];
  var sheet = SpreadsheetApp.getActiveSheet();

  var result = pattern1(data);
  var result = pattern2(data);

  sheet.getRange('a1').offset(0, 0, result.length, result[0].length).setValues(result);
}

function pattern1(data){
  var ar = [];
  for (var i in data){
    for (var key in data[i]){
      ar.push([key, data[i][key]]);
    }
  }
  return ar;
}

function pattern2(data){
  var ar = [];
  var keys = [];
  var values = [];
  for (var i in data){
    for (var key in data[i]){
      if (i == 0) keys.push(key);
      values.push(data[i][key]);
    }
    if (i == 0){
      ar.push(keys);
      keys = [];
    }
    ar.push(values);
    values = [];
  }
  return ar;
}

If my understanding for your questions was wrong, I apologize.
