I’ve installed MS Excel on my MacBook Air this week. Only a day ago I got a problem. It worked less than a week without troubles. My huge document on work, it’s my report stopped opening. Excel writes: Excel found unreadable content in Madison_Report.xlsx. One of my friends, he works as IT specialist, he tried to repair xlsx, but it was unsuccessfully. Is there any way to do it on Mac?
Try opening the document in Text edit or Pages, if you have it.
For Macintosh products some months ago was created special instrument, it is called Apple Online Service - you may find it here - https://onlinefile.repair/en/excel.html - as people say it helps to handle various troubles with data.
