I know that the open source programs don't provide all the features of MS Office, but it was my only possible choice. I searched for an Office 2016, but I wasn't able to find something that was 100% original without any doubt...
It's not about the features... it's about MS Office's unique macros (macroinstructions)... they are

programmable patterns which translate a certain sequence of input into a preset sequence of output.

In gross terms, an inter prog language/ punctuation architecture.

Again, genuine Office programs are out there... didn't get mine on Amazon, but I do buy my AV suite

(Kaspersky Internet Security 2019) license through them and it's 100% safe and legit- for ~ 1/6 the

price of what Kaspersky charges for renewal... You'll just have to search...try eBay.
