open source alternative to MS Office

Apache OpenOffice is the only one I know of. I used it for a while but reverted back to MS Office.

While Microsoft Office dominates the productivity app sector there are many flexible alternatives. In this guide, you'll learn more about some of them.

Many free and open source suites such as LibreOffice support the Open Document Format, which is used by the UK government. Open standards are useful as when developers discontinue software, users may not be able to access documents stored in a proprietary format. This has happened in the past to former users of Microsoft Works.

If you manage an organisation, you may be unable to pay for MS Office software licenses for every machine. For this reason all the products discussed here are available free of charge, or offer a free tier such as WPS Office.

Some of the tools in this guide also incorporate useful features not found in Microsoft Office, like converting PDFs to DOC format. All of the suites listed below can both open and save Microsoft Office documents such as DOCX, XLSX and PPTX.

I've been using Apache Open Office for years.

Open Office is a good alternative, but there are others if you're willing to work online, you can use the free online version of Word, Excel, Powerpoint. See Onedrive.com. You do need a Microsoft free account.
Or, you can also use Google's free online apps, Docs, Sheets, Slides. They can be used offline as well. See Drive.com.

Microsoft Office 365 is $9.00 per month and includes up to five installations as well as web based versions of the software that can be used from any browser. This includes One Drive storage as well.

I like Apache Open Office but LibreOffice is an off shoot of it and works well also.

I got a fully licensed copy of MS Office Pro for less than $50. A lot, evidently, of businesses buy software with a multi computer license and don't use them all. It is legal to sell them and MS will even update them for you. I looked on ebay for them and I have 2010 currently but I'll be updating soon because the company mine came from updated to 2018 or something like that and while the license is lifetime MS is trying to get all the copies updated, not a big deal at all but freaks the DW out.

I’ve used Open Office and Libre Office in the past and both work well. I don’t remember (but they may) either having a Publisher replacement. For the most part they are compatible with MS Office, but I did have issues with some formatting, and even though they allow saving documents in eith ODF or MS formats, people I would send files to could not always read them properly. I have since dropped all Office products as I no longer need the full power they provide and anything I need to do in a spreadsheet or letter can be done on my IPad with Apple apps. I got irritated at MS too as they offer office apps on IPads for free (or did) EXCEPT for the IPad Pro which of course is the one I have.

I bought Microsoft Office Professional Plus 2016 for $39.
Had to download it and got the key by email.

Do a Google for it.

... or you could do a duckduckgo for it also.
