> The two office suites take very different paths here. LibreOffice uses the OpenDocument Format (ODF), an open standard meant to be controlled by no single company. Microsoft, on the other hand, created its own Office Open XML (OOXML) to support every feature in its own software, giving us the familiar .docx and .xlsx

It's so impressively underhandedly sneaky that Microsoft named their ODF-competitor format “Office Open” just as OpenOffice.org's (LibreOffice's direct ancestor) hype peaked with OO.o 2.0 having ODF as its native format, when MS Office finally had a viable and popular competitor for like the first time ever.

I feel qualified to opine on this as both a former power user of Word and someone building a word processor for lawyers from scratch[1]. I've spent hours pouring over both the .doc and OOXML specs and implementing them. There's a pretty obvious journey visible in those specs from 1984 when computers were under powered with RAM rounding to zero through the 00's when XML was the hot idea to today when MSFT wants everyone on the cloud for life.

Unlike say an IDE or generic text editor where developers are excited to work on and dogfood the product via self-hosting, word processors are kind of boring and require separate testing/QA.

MSFT has the deep pockets to fund that development and testing/QA. LibreOffice doesn't.

The business model is just screaming that GPL'd LibreOffice is toast.

I loved OpenOffice.org back in the day, but in today's world with no modern web collaboration option it is dead. I'm aware of the attempts to make it run via browser, and no, they aren't really there, not even close.

What we need today is a web-first suite of apps that does everything Google Docs/Spreadsheets/Slides do, but uses OpenDocument family of standards as their native file format.

How did this make the HN homepage? There isn't even any news here. It is an argument about ~20-year-old XML file formats, at a time when file formats couldn't matter less?

On top of that, Office supports OpenDocument formats, just like LibreOffice supports Office formats.

Also, IME the Office XML file format is far better supported by third parties - countless apps read/write them. I have multiple apps installed that can read/write an Office file, but MS Office is the only app on my machine that opens OpenDocument.

Its been Microsoft's strategy since its formation to make a lot of proprietary technology when it moves into any space and do so in a way that locks customers in such that if and when it is no longer the top product the customers can't easily leave. They do this in every single product and market they operate in. Where they can't ultimately win they buy their competitor and integrate the product then slowly kill it.

    It is important to remind people of this, because they imagine that MS is integrating open source projects like git, linux, and others for the goodness of their heart. It's well know that this is just step 1 of embrace, extend, and extinguish. Next step (underway) is to add many features that will work only under the MS ecosystem and finally declare those original tools as legacy that should not be allowed in corporations.

        The point that he's a con man is that he signed a document with IBM to supply an OS when he had none. Of course in retrospect he was "smart" to go around and buy one, but in fact he was promising IBM something he didn't have and in an alternate universe he could be sued for that.

It’s not just the complex XML based format. Word has collaboration tie-in’s with Skype, Teams, SharePoint, OneDrive etc

It’s an entire ecosystem

Also, I have tried to use LibreOffice and you have to learn an entirely new tool. The user interfaces are different. Word has its own issues of course but LibreOffice does not feel as polished

There are things in Word that are legacy and carry overs from another time that carry various nuance. It’s not all documented set of features either

Trying to replicate the entire look and feel is incredibly difficult

Most people are going to encounter Word in a corporate setting and to have them switch to another tool is going to a big hill to climb

  • freeopinion 3 hours ago

    I have met very few non-techies that could tell the difference between Word and Wordpad or use them any differently.

    This "big hill" you mention is a fantasy.

    • trelane 3 hours ago

      You're right for home users. In businesses, the hill is also that some users are power users that have locked themselves in, in slightly different ways between the different power users. Also the company has also locked itself in by drinking deeply from the Microsoft well (e.g. AD and sharepoint and Windows etc) and marketing away will cost them a lot of time and effort, and therefore money.

      • ghaff 2 hours ago

        If the lawyers and the financial analysts need Windows Office for certain uses let them use them. But I'd note that the first edition of a book I wrote a while back had a Sharepoint workflow and had moved away by the second edition.

        The licensing/support is cheaper carries some weight. But Windows to Linux mostly didn't win a lot of fights on the desktop. But Google Docs for collaboration and general simplicity does win over a lot of companies.

        My comment was focused on Word. There is definitely a lot of lock-in for the larger MS ecosystem in business. But that is the nature of large bureaucracies.

  • jasonjayr 3 hours ago

    At one point LibreOffice + MS Office were pretty much on par with each other.

    But MS has built this giant moat of integrated proprietary services around these systems that make it difficult to switch away once you are sucked into the environment.

    It takes a pretty sizable expense to switch to anything else, while satisfying all of a companies different workflows for various roles and levels of experience.

        • eddythompson80 2 hours ago

          I don't know much about advanced Google Docs, but I know that's the far from true for Google Sheets. Google Sheets covers a shit ton of ground that Excel covers, but a serious user can never replace Excel with Sheets.

          We had a lot of marketing and sales people who wanted to use Google Sheets instead of Excel to load sales reports from a shared PG database. This is of course a built-in feature (loading a PG table as a sheet) in Excel. Google Sheets obviously doesn't support any imports. They are all paid plugins, and they all make you pay per row or cell or column.

          You can write a plugin to do it, except their funky AppScript (which is a custom synchronous Javascript/V8 environment where there is no async or callbacks, and promises block.

          Except, the plugin can only connect to MySQL. PG support ask has been open since 2011. They decided in 2014 that they don't plan to support PG. Then in 2018 they thought maybe they can only support GCP Postgres.[1]

          Ok, fine. You make your own API to call and load data. No, you can't return more than 50 MBs. So better split your query.

          Oh, you want to load a 50MB CSV? There are 3 different APIs for that:

          - "Import from GDrive". This is the one you want. Import 50MB in a couple of seconds. But it also requires the most permissions to full access the user's GDrive

          - "Basic Import API". This imports at ~100kbps but not always. gets slower for large data

          - "Advanced Import API". This imports at ~250kbps but not always. gets slower for small data

          and you need to run your own benchmarks[2][3] to understand which API to use in which context, then keep reruning them as things change.

    I use word processors so rarely that every time it's like learning a new tool. Whether it's Word, Google Doc, LibreOffice, or anything else.

    I will say that Google Docs and Word both feel a bit more "polished" than LibreOffice which still feels very distinctly like a 1990's era desktop program. I guess because it is.

I didn’t realise we’d entered a time machine to 2007. I’ve worked extensively with OOXML and yes, the documentation is cryptic and often absent, but Microsoft will help you out if you contact them on their forums. I see Libre Office devs there all the time!

But the complexity is not some kind of conspiracy - it’s inherent - it comes from the fact that Office is ancient and very, very complex with a huge number of features. Many features are implemented in backwards compatible way on top of the old version of similar features and then the whole thing has been back ported from a bunch of C structure to XML which has the most woeful and underpowered schema language imaginable.

  • troupo 3 hours ago

    > it comes from the fact that Office is ancient and very, very complex with a huge number of features.

    IIRC one of the many unfortunate decisions made by MS with OOXML (whether intentionally, or not, or both) is to codify a lot of display and formatting quirks directly in the schema with very little explanation or docs. Instead of making it s different namespace or layer.

    So, to implement OOXML, you also needed to reverse engineer, say, behavior of Word97 etc.

I know about the lack of tech-savvyness of most humans, but isn't Markdown and Pandoc—if you slam a GUI in front of it—covering the needs of 99% of users?

Granted, when you need formatting, like for a formal letter, you use a template someone made but this is not what most people use Word for.

And don't get me started on "people wouldn't understand how to put things in bold or italics"; they can barely use Word anyway. Might as well use something much simpler. Office "productivity" suites are over to me.

Everyone needs to stop competing with Office and just build a better office.

The truth is, no one needs to be compatible these days. Everyone is either:

- using the same software company-wide, whether it's LO, Google Docs or MS Office

- exporting to PDF when sharing docs with someone outside the organization

The real thing that LO is missing is server side hosting and easy syncing... Until they get that, it's just going to be something used by individuals and small orgs.

I still remember, at my university we had LO installed on lab computers, MS Office was a "requirement" for students to purchase, but most profs simply insisted we simply hand in assignments as Google Docs links because there was incompatibilities between .doc, .docx, the formats made by LO, etc... Google Docs were the only ones that could be shared and be 100% identical on every computer with the link.

If LO had a web hosted solution and provided easy to install server code for organizations, they'd dominate. But they don't...

    The PDF spec is well designed to be both very expandable and easily readable.

    It's absolutely horrible to try and edit.

    That's because the structure of a PDF is essentially a bunch of media "streams". It's very easy to say "render a jpeg at this location on the page" but that's about it. It doesn't store, for example, the fact that you might need to wrap words around a page. Instead, it's "Here's a box with text in it".

    The only thing that really could make PDF rendering hard is adobe put a whole bunch of garbage into the spec. For example, the full spec had the ability to run javascript and flash at one point (not sure if it does anymore).
