The getRange operation will return an array containing an element for each cell in the specified range.
// Initialize SheetSearch
var sheet = new x_vivid_sheets.SheetSearch('a5431dcc1b580210cf82ece03d4bzbab');
// Call getRange with the range of cells you're looking for
var cells = sheet.getRange('B3:D3');
// Return value is: [{"cell":"B3","value":859},
// {"cell":"C3","value":"Kentucky"},{"cell":"D3","value":42}]
gs.info(JSON.stringify(cells));
