Toad for Oracle 12.8 Export Grid to Excel - Use Only 'General' Cell Formatting disappeared

Hi everybody.

I usually use Toad for Oracle to exctract some data from our Oracle DB and export the results to Microsoft Excel.

I updated my Toad client to the 12.8 and now, when I export the grid to Excel, all the "number" columns are exported with decimal separator "." .... that I don't want. Where is the 'Use only "General" cell formatting" option?

Thanks for your help
