Write to Spreadsheet File vi doesn't work in xlsx format

Hi, I have used Write to Spreadsheet vi sending data to xls files. It didn't work now when associated with xlsx file. I got error message when opening the data file:

Excel cannot open the file because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file.

Is Write to Spreadsheet.vi made for xls format only?

Is there an equivelent version for xlsx format?

Thanks,

Anne
