I found in the UI of Google Spreadsheet the functionality Text Rotation but i found no equal function in google apps script.
So how can i rotate Text with Google apps script?
Regards
Edit: I created a Spreadsheet with the needed rotation as default setting after this a make a copy of this spreadsheet.
I know this is an old ask but incase others are interested...This can be done now. Just add .setTextRotation() to any range selected and it will rotate the text to the desired degree. For example:
SpreadsheetApp.getActiveSpreadsheet().getSheets()[0].getRange(1,1).setTextRotation(-45);
