Returns the column number of the last column that has content.
class SpreadsheetApp method .getLastColumn()
SpreadsheetApp is the Apps Script service.
.getLastColumn() is the method name you will see after a dot in your code.
What it does
Why it's used
- Detect how wide a table is before looping across columns.
- Know where to write the next new field without hardcoding column letters.
Common errors
- Forgetting parentheses on getLastColumn. Write SpreadsheetApp.getLastColumn(), not SpreadsheetApp.getLastColumn or getLastColumn by itself.
- Skipping dots between chained calls. Each step needs a dot, like SpreadsheetApp.getActiveSpreadsheet().getSheetByName('Data').getLastColumn().
- Adding spaces where they do not belong. Write SpreadsheetApp.getLastColumn(), not SpreadsheetApp .getLastColumn(), SpreadsheetApp.getLastColumn (), or SpreadsheetApp . getLastColumn().
- Wrong capitalization. Use SpreadsheetApp and getLastColumn, not spreadsheetapp or getlastcolumn.
