Creating a JSON object from Google Sheets

Question

I am trying to learn AppScript and I am using Google Sheets as an example. I want to create a simple JSON object using some data populated in the Sheet.

I know it's been a while, but I came up with a slightly more flexible solution. I've created an aptly named function that converts spreadsheet data to objects, given a set of headers and a set of rows.

function convertToObjects(headers, rows)
{
  return rows.reduce((ctx, row) => {
    ctx.objects.push(ctx.headers.reduce((item, header, index) => {
      item[header] = row[index];
      return item;
    }, {}));
    return ctx;
  }, { objects: [], headers}).objects;
}

You can call the above function like this:

var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('YourSheetName');
var [headers, ...rows] = sheet.getDataRange().getValues();
var objects = convertToObjects(headers, rows);

If you need to ignore the first row and get headers from the second row (like I do), then you can do this instead:

var sheet = SpreadsheetApp.getActiveSpreadsheet().getSheetByName('YourSheetName');
var [_, headers, ...rows] = sheet.getDataRange().getValues();
var objects = convertToObjects(headers, rows);

If you have any improvements to this, please let me know in the comments below.
