Computer software question about Windows 11 and Microsoft Office

I know this is probably the wrong forum, but I'm looking for a quick answer...

I have a Lenovo desktop PC with Windows 10 that is pretty old...maybe 8-10 years?

It is my understanding that Windows 10 will no longer be supported by Microsoft, with the deadline soon approaching.

I will be buying a new desktop with Windows 11 installed.

I have been using a ridiculously old version of Excel and Word on my desktop. These Microsoft Office versions have been installed using a CD. I think it's Office 2000?

I have thousands of Excel files with the .xls suffix.

I found a new desktop PC (I found a decent Lenovo - I like this brand) brand new, for about $400. However, there is no CD drive on the new computer, and I don't feel like buying an external optical drive just to try to install my old version of Office. Additionally, my limited Google research tells me that windows 11 will not reliably function with Office 2000.

So my plan is to also purchase a Microsoft Office 2024 software package along with the new computer.

All of the above words for one stupid question: Will the new Microsoft Office software package be able to read and use my current 20 year old .xls files? Same with my current old Microsoft Word files?

Thanks in advance for any input.

When you save any changes, it might prompt you to save as xlxs instead of xls (which you should do) but that should be the only thing you might come across.

Backward compatibility is quite good with the Office suite, particularly Word and Excel. You'll be prompted to open them in "compatibility mode" because there are new formats in newer versions of Office that are designed to mitigate viruses or macros doing bad things to your PC. I recommend any file you open you update it, but that is not required.

Try Libre Office. It is free and well supported and will open/save in all of the Office format. it's at www dot libreoffice dot org

YOu could also use OpenOffice which is derived from Office. It's also free from www dot oepnoffice dot org. It will show up as Apache Open Office.

Both of these work and are about 98% compatable. There are only a few exotic features of Office not supported. The plus side is both interfaces look like the old version of Office you know

Don't use office much these days, but I have Office 2003 installed. Works just fine with the newer office document.

There are a couple of patches/upgrades I need to apply first to the old windows installation. I have them stored on a drive, if you need them I can upload somewhere.

After doing this, I can read/write docx and xlxs documents and save them in the more modern format.

You can even read and process and write them on macs and linux. Either with Apple's apps (Numbers and others) or with Libre Office (free and open source, runs on everything).

doc and docx, ppt, pptx

So your files are safe.

BTW, look into libre office. It might save you a lot of money, with (hopefully) minor or zero glitches. Free to try (and use). No subscription. No cloud required.
Office replacement.

https://www.libreoffice.org/

Free as in Freedom.

It’s now “Microsoft 365.” https://www.office.com/

I generally prefer MS365 or older versions of Office because it always stays up to date. The exception is I use the “classic” Outlook rather than the “new Outlook’ because the new Outlook is web-based and I am used to the old one. I haven’t done much with Co-pilot.

One big advantage to Office 365 is that it can be installed on several machines for one price. So if you have a desktop and laptop, you don't have to buy it twice. Plus, you get 1 TB of Onedrive storage

Your spreadsheets will open in later versions of MS Office, including 2024. They may open in compatibility mode (first link) and you can convert them to the newer xls if you need to use all the 2024 bells and whistles(second link).

I downloaded it on my current computer, soon to be replaced, and did some testing on it. It seems fantastic for spreadsheets, and also for word documents, and it looks just like my worksheets in Excel.

I never would have known about this if it wasn't for DU. You folks saved me a few bucks by not having to buy new Microsoft Office software to replace my old, and currently lagging, Microsoft 2000 office.

I found a decent Lenovo computer at best buy for only $350, and the specs are good enough for what I use a computer for. I purchased it online tonight.

So, I thank you for the advice.
