Microsoft Office problem

Question

I just tried calling Microsoft Customer Service/Technical Support at 877-696-7786. At every turn I was told “support has moved online,” meaning I could get no live person on the phone to solve my problem. So here’s my problem: I cannot open, either on my iPad or my Windows laptop, an Excel spreadsheet that I update every week. I last updated it two weeks ago and saved it to Dropbox on my iPad. (That was the first time I’d attempted this on my iPad; I’d always used my laptop prior.). Last week, and again today, when attempting to open it on both devices, I’m being told that “Excel cannot open the file ‘(name of file)’.xlsx because the file format or file extension is not valid. The file extension is the same file extension (.xlsx) on other Excel spreadsheets I have in Dropbox which open up no problem. There’s nothing wrong with the format either. I need help! When I asked via “chat” with a support specialist if there’s a phone# I could call to get to a live person, I was taken to a form to fill out along with a credit card number. I was told it’s refundable. But if I can never get through to a live person I have ZERO confidence my credit card purchase will be refunded. I want to TALK TO A LIVE PERSON PLEASE. Can you help me resolve my problem?????

Answer 1

Maybe Dropbox converted the file type, or potentially it's changed the file extension? Are you able to download a copy of the file from DropBox to your desktop and try renaming it to have the original extension (probably .xlsx, although it won't hurt anything to try others).
