Returns how many columns are in a range.
class SpreadsheetApp method .getNumColumns()
SpreadsheetApp is the Apps Script service.
.getNumColumns() is the method name you will see after a dot in your code.
What it does
Why it's used
- Iterate columns in a dynamic range without guessing width.
- Build column headers from the range size.
Common errors
- Forgetting parentheses on getNumColumns. Write SpreadsheetApp.getNumColumns(), not SpreadsheetApp.getNumColumns or getNumColumns by itself.
- Skipping dots between chained calls. Each step needs a dot, like SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').getNumColumns().
- Adding spaces where they do not belong. Write SpreadsheetApp.getNumColumns(), not SpreadsheetApp .getNumColumns(), SpreadsheetApp.getNumColumns (), or SpreadsheetApp . getNumColumns().
- Wrong capitalization. Use SpreadsheetApp and getNumColumns, not spreadsheetapp or getnumcolumns.
