class SpreadsheetApp method .insertColumns()
SpreadsheetApp is the Apps Script service.
.insertColumns() is the method name you will see after a dot in your code.
What it does
Why it's used
- Add a new metric column without breaking existing formulas.
- Insert a helper column for IDs or calculations mid-table.
Common errors
- Forgetting parentheses on insertColumns. Write SpreadsheetApp.insertColumns(), not SpreadsheetApp.insertColumns or insertColumns by itself.
- Skipping dots between chained calls. Each step needs a dot, like SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').insertColumns().
- Adding spaces where they do not belong. Write SpreadsheetApp.insertColumns(), not SpreadsheetApp .insertColumns(), SpreadsheetApp.insertColumns (), or SpreadsheetApp . insertColumns().
- Wrong capitalization. Use SpreadsheetApp and insertColumns, not spreadsheetapp or insertcolumns.
