I believe your goal as follows.

• You want to select all rows using Google Apps Script.

In this case, how about the following sample script?

Sample script:

function muFunction() {
  SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("C:C").activate();
}

• When this script is run, the column "C" of "Sheet1" is selected.
• For example, when "C:C" is modified to "C2:C", the cells "C2:C" are selected.

Note:

• From I want to delete all the rows that I don't need on Google Sheets, my data has a table header. , when you want to clear the rows except for the 1st header row, you can also use the following script. When the following script is run, the cells "C2:C" of "Sheet1" are cleared.

   function muFunction2() { SpreadsheetApp.getActiveSpreadsheet().getSheetByName("Sheet1").getRange("C2:C").clearContent(); }

• From What's the code equivalent for Command + shift + down? , in this case, I thought that the following script is the result you expect? When you use the following script, please select a cell and run the script. By this, the rows of the data range after the selected cell are selected.

   function myFunction3() { const activeRange = SpreadsheetApp.getActiveRange(); activeRange.offset(0, 0, activeRange.getNextDataCell(SpreadsheetApp.Direction.DOWN).getRow() - activeRange.getRow() + 1).activate(); }

• activate()
• clearContent()
• getNextDataCell(direction)
