Returns the total number of columns the sheet can hold.
class SpreadsheetApp method .getMaxColumns()
SpreadsheetApp is the Apps Script service.
.getMaxColumns() is the method name you will see after a dot in your code.
What it does
Why it's used
- See how many columns the sheet supports before adding fields.
- Guard against running out of room on wide datasets.
Common errors
- Forgetting parentheses on getMaxColumns. Write SpreadsheetApp.getMaxColumns(), not SpreadsheetApp.getMaxColumns or getMaxColumns by itself.
- Skipping dots between chained calls. Each step needs a dot, like SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').getMaxColumns().
- Adding spaces where they do not belong. Write SpreadsheetApp.getMaxColumns(), not SpreadsheetApp .getMaxColumns(), SpreadsheetApp.getMaxColumns (), or SpreadsheetApp . getMaxColumns().
- Wrong capitalization. Use SpreadsheetApp and getMaxColumns, not spreadsheetapp or getmaxcolumns.
