Welcome to this very short daily blog where I give a very simple script to automate Google Products. In this chapter, we'll custom menu that'll delete empty rows and columns in current active spreadsheets.

Delete Empty/Extra Rows and 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 to select the custom menu, It will check all the extra rows and columns after the last rows and columns with data.

  3. Then delete all those extra rows and columns.

function deleteExteriorRowsNColumns() {
  // get sheets and data
  const sheet = SpreadsheetApp.getActiveSheet();
  const data = sheet.getDataRange().getValues();

  // determine last row and column
  const lastRow = data.length;
  const lastCol = Math.max(...data.map((arr) => arr.length));

  // get maximum rows and columns sheets
  const maxRows = sheet.getMaxRows();
  const maxCols = sheet.getMaxColumns();

  // only remove rows and columns if there are empty rows or columns beyond last row and columns
  if (maxRows > lastRow) {
    sheet.deleteRows(lastRow + 1, maxRows - lastRow);
  }
  if (maxCols > lastCol) {
    sheet.deleteColumns(lastCol + 1, maxCols - lastCol);
}

}

/**
 * OnOpen trigger that creates menu
 * @param {Dictionary} e
 */
function onOpen(e) {
  createCustomMenu();
}

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

  menu.addItem("Delete Empty Rows and Columns", "deleteExteriorRowsNColumns");
  menu.addToUi();
}
