I just upgraded my MacBook Pro to a 2017. My previous MacBook had Microsoft office as I need the word and excel for work. I'm trying not to purchase a new version of Office. Someone suggested Chrome, Chromevox, doc, sheets.... as I can use my work documents in that forum and when sending back to office, they'll still be able to open. I can't seem to find the right site to review it , where to download, are they are all separate or together. Suggestions appreciated.
