Some days ago one of brothers worked in Excel 2016, and today when I opened my .xlsx file, I saw - Microsoft Excel has encountered a problem and needs to close. I used open&repair, but it restored even a half of data. I need some Excel recovery tools or methods.

Well I recommend to ask to Microsoft Support or Data Recovery service.

This site really isn't for discussing new products like this. The OP sounds a lot like a copy-paste spammer. (expect another new user to post a link to a "repair utility"/malware)
