Would you like to separate the column in your spreadsheet that consists of the full names of people into first and last names? Well then stick this very simple script to your spreadsheets apps script editor and you'll be able to do just that.

Split The Selected Column

The following bound script will do three things:

  1. Create a custom menu in your spreadsheets tabs with the title Custom Menu.

  2. After you call select the custom menu, It will check the cell you've selected to split into. The script won't work if you don't select a cell in the right column.

  3. Separate the whole column into two columns, with the first value in the first column and the second(& rest if there are any) in the new column.

function splitName() {
  // get sheet and data
  const sheet = SpreadsheetApp.getActiveSheet();
  // get selected row
  const activeColIndex = sheet.getActiveRange().getColumn();

  const data = sheet.getDataRange().getValues();
  const lastRow = data.length;



// if you're new and only want this feature the use this code
 * OnOpen trigger that creates menu
 * @param {Dictionary} e
function onOpen(e) {

 * Menu creates menu UI in spreadsheet.
function createCustomMenu() {
  let menu = SpreadsheetApp.getUi().createMenu("Custom Menu"); // Or DocumentApp or SlidesApp or FormApp.

  menu.addItem("Split Names", "splitName");
