✔ Best Answer
There is a viewer for those files, although I was under the impression that Excel 365 already included it?

Not using 365 or win-10 I can’t confirm (I use Libre Office and Mac systems).

This is a link to the MS viewer

Office 365 should read either .xls or .xlsx but the file extension on your older .xls files should not have changed. Select one, make a copy of it, manually change the file extension back to .xls, save, & then see if it will open properly.

If your file extensions aren't enabled, open File Explorer Options, click on the View tab, uncheck the box next to "Hide extensions for known file types", then click Apply

What's the exact error message? Perhaps it's having problems reading the disk (disc) instead of not being able to interpret the .xls extension...

johnw, I was able to convert the file with .xlsx extension to .xls easily. But I have to be a member to open up the converted .xls file. Office 365 will not open up .xls files acc to their bulletin.

T-R-A, Office 365's bulletin says it will not open .xls files

Seems MS-land has decided to drop support for earlier file formats? Decided yet again to phyxe what ain’t broke... i.e. break it.

I have Office 365 on Windows 10 and I can confirm that Excel opens .xls files without any problems. So far. Better not jinx it...

I gave up on the whole Office suite once they started to go the charge a fee for it each year; and promote it as an online resource rather than a local DVD (or whatever) installation. Whilst one can download and instal - for fixed once only fee, the upgrades/support appear to be quite different compared to the online fee version?

I use Libre Office - totally free - although they do appreciate a wee donation). Is fully Word/Excel compatible; but has no Outlook (equivalent). For the later I use Thunderbird (also free etc...) - recommended by many of the regulars here. Libre Office reads/writes "all" the assorted files version used in Word/Excel - whatever version, generation.

A wee learning curve for both of the above but nothing difficult.

They said on TV news that Office 365 was taken down by a
hacker attack. Could that be your problem?

I would be really surprised if Office 365 can't open both xls and
xlsx files when it is working normally.

re: "I use Libre Office - totally free - although they do appreciate a wee donation). Is fully Word/Excel compatible"

We need to be careful with the word "fully" when we discuss compatibility.

For some of us, VBA macros are an integral part of our Excel and Word usage. While Libre Office's compatibility with Excel VBA is much better than it used to be, there is still some VBA code that must be edited in order to work Libre office. Workbooks that contain macros cannot always be swapped between the two applications without some modifications.

Fair and valid comment by DD.... For general use it is ok with MS files, but as DD advises more complex aspects it may not be so.

I found one Excel formula went over nicely to LO, but another (conditional full of “if then this” etc.) another didn’t.

I have yet set about recreating that one in LO.

I was able to convert .xlsx to .xls with johnw's link but cannot open the file as I said earlier.
But, thanks though. trvlr's link to view the .xls is what I am using for the file I converted.

I was attacked by a Hacker about 2 weeks ago and as Jeff Root said it might be the cause knowing that 365 reads both .xlsx and .xls. So, I plan to uninstall Office 365 and reinstall the app. See what happens.
