Hi @monir-akhavan,
Welcome to the Community. I'd be glad to assist you with exporting your report into an Excel file.
So that I can best assist you, could you please provide some additional information about why you're unable to export the report? Knowing this will help to ensure that I'm able to get you the best resolution.
In the meantime, I recommend the following article, which includes steps and a visual guide for this process: Export QuickBooks Online Reports to Excel.
Looking forward to your response. Wishing you all the best.
