LibreOffice

It's basically the free, open-source version of Microsoft Word. I have been using it for over a decade now (back when it was called Open Office), before Google Docs even came out. If you need to open a Word document that Google Docs can't open but you don't have Word, LibreOffice is great for that.

It doesn't open word doc format perfectly all the time. There are still some marginal differences some times. Which is okay, it is not expected to. But it can be great if that could be done.

It's totally free and open source and it gets regular updates which is awesome!! It is close enough to Office suite that it can be used as a great alternative to Office if you don't want to pay for it or didn't get it included with your computer.

The most annoying thing is saving documents into office file types. You have to actually export the document and then pick from the many file types. If you have just save it saves it into LibreOffice's own file type which when sending it to clients they don't know what that is or how to use it.

Well, obviously the main argument to use LibreOffice is that it's released under a free license and therefore free to use, in general. But aside the zero price, LibreOffice plays an important political role that affects companies all over the world: Microsoft Office is the undisputed market leader in native Document software, which effectively keeps people and organizations from switching to free operating systems, since it's dependent on either a Microsoft operating system, or an even more expensive macOS. Given the previous monoculture in this space, the importance of LibreOffice as a free alternative, that can be made to run on any operating system and even be used web-based is outstanding. Writer and Calc, the most important ones, are not perfect but usable pieces of software I would recommend to my mother. The worry about file format incompatibilities with Microsoft Office seems to be much less of a problem nowadays. And I would recommend you anyway to use free document formats inside your organization and PDF Forms (LibreOffice Writer and Draw help you with that.) and HTML sites for everything that leaves the house.

Bad experiences mostly come from LibreOffice Impress. It works for me to create simple presentations with simple animations, which is everything I need. But even that is kind of annoying: Creating a blank slide involves changing the "Master Background" which is apparently decoupled from the slide layout, which is as unintuitive as it gets, and often starting an itemized list creates arbitrary bullet sizes, indentations and font styles you have to take care of.

We use the software on Linux computers (due to faster data processing). The financial savings are great, we saved a significant amount on licenses, which could be invested in other software. Thanks to Linux, another advantage is the processing speed, by which I mean mainly the base and calc program.

In its current form, version 6.4 can be criticized, the software is completely comparable to Microsoft Office, support also works without problems. The only problem is that employees have to learn it (mostly they know microsoft office).

LibreOffice is easy to use and allows me to make any calculation easily. This software is essential to manage sales or purchases in my organization, since I can keep all the data sorted. On the other hand, it is free software, so you save a lot of money that costs a license of a spreadsheet software. Also, I also like that it has Excel support, so I can open the same documents in both programs without the documents changing their structures.

I cannot criticize software that gives me totally free features and that are fundamental to my daily work.
