How can I store a range of cells to an array?

Question

If I have a list of data in cells A1:A150 (but the amount can vary), is there a way to push that into an array without looking at each cell individually to determine if it i

Answer 1

Try this:

    var sheet = SpreadsheetApp.openById(SHEET_ID).getSheetByName(SHEET_NAME);
    var lastRow = sheet.getLastRow();

    var data = sheet.getRange(1, 1, lastRow, 1).getValues(); //getRange(starting Row, starting column, number of rows, number of columns)

    for(var i=0;i<(lastRow-1);i++)
    {
      Logger.log(data[0][i]);
    }

the variable data stores all the cells of column A.

Cell A1 is stored in data[0][0], cell A2 is stored in data[0][1], cell A3 is stored in data[0][2] and so on.

The getRange(starting Row, starting column, number of rows, number of columns) is a batch operation so it is much faster when you have a large dataset.
