MS Office type program recommendation

[Old Geezer]

Being a luddite, I've finally upgraded to W10 on my new machine. Can't say I like very much, but needs must!
My old W7 PC had Office 2003, which I used Outlook, Word, and Excel.
I don't need Outlook any more as I have Thunderbird now, which I like and works well enough for my needs.
So I'm looking for recommendations for substitutes for Word and Excel, but must be able to access and edit all my previous Office2003 docs.
I can't justify spending a wad of cash on Office 365 because of the very occasional use they would get. Also I don't want to be storing my stuff online/onedrive/cloud/you name it.
Your thoughts please folks. TIA
Cheers, Trev.

LibreOffice -or- OpenOffice - I have used, recommended and installed them for years, despite having multiple (unused) legal copies of Word, Excel, PowerPoint and MS-Office.

Do you have a microsoft account ? If its fairly basic docs, then there is the free online versions of office available through your MS account.
