To use this script in Google Drive:
- In your spreadsheet, click Tools->Script Editor.
- Paste the contents of Code.gs into the editor.
- Save.
- Select "Allow" when Google asks about permissions.
- Reload your spreadsheet.
You should now see a new file menu option, "Export".
Yes indeed. I suggest using hideSheet() instead of deleting it. In this way, you avoid having issues with charts that make use of data in other sheets!
// Hide redundant sheets.
var sheets = destSpreadsheet.getSheets();
for (i = 0; i < sheets.length; i++) {
if (sheets[i].getSheetName() != sheetName){
sheets[i].hideSheet();
}
}
