Category: Open Document Format

The complexity of the OOXML format is linked to its design and was deliberately created to make the format more difficult for non-Microsoft software developers to implement. Compatibility issues are caused by a veritable “maze” of tags used even for the simplest content, which binds users to the Microsoft ecosystem in the first example of standard-based lock-in.

The DOCX case

To demonstrate the difference in complexity between the XML schemas of Writer and Word text documents in the ODF and OOXML formats, I used two classic English theatre plays: William Shakespeare’s Hamlet and Oscar Wilde’s The Importance of Being Earnest. I downloaded the text versions of these works from Project Gutenberg — a library of classic texts for which US copyright has expired — and deleted the introductions and conclusions added by Project Gutenberg, without making any other changes.

I then repeated this process for both documents.

I copied all the text and pasted it, without any formatting, into two newly created blank documents. For Writer, I used the template that I usually use for unstructured documents; for Word, I did not use a template. This means that, in Writer, the XML schema contains information about the template (margins, paragraph and font formatting), but this does not increase its complexity.

To perform the analysis, I duplicated and renamed the two files, replacing the original extension with “ZIP”, and then decompressed them to create two folders containing all the files of the respective XML schemas.

The LibreOffice folder contained three subfolders and six files with the same names as those in the ODS file examined last week, as would be expected of a standard aiming to simplify life for developers and users. All the content is actually in the content.xml file, while the other files contain instructions for displaying the text document correctly.

The Microsoft 365 folder contains three subfolders and the [Content_Types].xml file, as with the XLSX file examined last week. One of the subfolders has a different name, but this is related to the application and does not increase complexity. Opening the [Content_Types].xml file provides information about the other files, including those in the subfolders.

In this case, the content is in the document.xml file inside the Word folder, which contains folders and files that differ completely from those in the XLSX file. Again, there is no technical reason for this difference in the XML schemas of the two files other than to make their internal structures different and more complex.

Let’s now analyse William Shakespeare’s Hamlet and then Oscar Wilde’s The Importance of Being Earnest.

Here is the PDF of Hamlet:

The difference in complexity between the document.xml and content.xml files is striking when you compare their lengths: the content.xml file has 6,802 lines, while the document.xml file has 60,245 lines, compared to a text document of 5,566 lines.

Let us now compare the two files’ XML schemas from the beginning to the end of the introduction.

It is a reasonably complex XML file. After the initial instructions on the sequence of content, the text of the tragedy can easily be located alongside the sequence of the five acts and the descriptions of the dramatis personae.

This XML file contains a lot of repetition. Is it really necessary to include the same information about the schema and style for every line of content, including empty ones? I doubt it personally, but since I am not a technician, I am willing to listen to reasons from those who argue that this content is essential and not artificial complexity.

Let’s see if the same thing happens with Oscar Wilde’s ‘The Importance of Being Earnest’. Here is the PDF:

earnest

 

In this case, the artificial complexity of the Word document is less apparent, as the content.xml file has 3,974 lines compared to a text document of 3,885 lines, and the document.xml file has 8,610 lines. Therefore, we have gone from a file that is almost ten times longer in terms of the number of lines to a file that is just over twice as long. This difference can be explained by comparing the first lines of the two files’ XML schemas (only those with content).

While the content.xml file retains all the line breaks (hard returns) of the text document, the document.xml file “reinterprets” the text, reconstructing all the paragraphs even when this makes no sense, as with lists of characters and the actors who play them. It also adds punctuation that does not exist in the text file, such as commas to replace hard returns. This is why the file is shorter than the “Hamlet” file, but it introduces an arbitrary “simplification” that does not respect the original document.

Until today, I was convinced that the XML schema of OOXML files was unnecessarily complex for the reasons I have explained at length on several occasions. However, it is not only unnecessarily complex, but also unnecessarily “creative” (always complicating the lives of developers and users).

Conclusions

Unfortunately, the reality is what I have explained several times, without going into technical detail. This has been confirmed by more technical analyses of XLSX and DOCX files, and I believe it will also be confirmed by next week’s PPTX file analysis. Microsoft has created an unnecessarily complex and incomprehensibly creative file format, which complicates the lives of developers and users more than I thought.

Indeed, while it is challenging to manage artificial complexity, it is arguably impossible to manage “creativity” that reinterprets the contents of a document by inventing paragraphs where it might make sense — albeit with a faithful format — and where it makes no sense, as with lists.

Perhaps, in my personal opinion, “creativity” was introduced to make it difficult for companies based in countries where reverse engineering is not illegal to emulate the OOXML format, as I don’t believe “creative” reverse engineering is possible, even with the help of AI.

Users should protect their rights by choosing an open standard format, such as ODF, which gives them control over their content and everything that this entails, including privacy protection, proper management of sensitive data and the ability to decide what to share and with whom.

This is a format whose development process, characteristics, and version are known; whose description corresponds to what happens on the user’s PC; and which faithfully reproduces the contents of the displayed document. It is a format that enables even less experienced users to identify and, in many cases, solve problems.

In short, it is the only open and standard document format that we would all like to have, but which only a minority use due to a lack of knowledge about the reality of the OOXML format, and the messianic trust that too many users place in Microsoft. This leads them to believe that there cannot be a commercial strategy behind a document format that is hostile to users’ interests.

The post, published on 18 July 2025, which explained why an artificially complex XML schema, such as that used by Microsoft 365 (formerly Microsoft Office) files, is in fact a subtle tool for locking in users because it is invisible and impossible to detect without in-depth study, was picked up by various IT media outlets. This was probably because it explained a problem that everyone faces without having the tools to solve it in a way that was accessible to everyone.

Some of these articles sparked a debate between those who supported my thesis and those who defended Microsoft, the true champions of lock-in, who claimed that the complexity of the XML schema was not artificial but rather a reflection of the complexity of the documents themselves.

This complexity relates to various factors, such as size (number of pages), structure (text, tables, graphs and images), content management (data entry by multiple people and systems) and customisation through metadata. These factors influence the management, classification and storage of the document itself.

The different approaches to complexity management between ODF and OOXML

However, the ODF and OOXML formats handle this complexity in completely different ways. In the first case, the XML schema seeks to simplify the work of developers and users by ensuring that both sets of requirements are met. Developers have all the descriptive tools related to document complexity at their disposal, and users can distinguish between descriptive elements and content because the two are almost always separate. The content is also consistent in syntax with the document.

In the second case, the XML schema does nothing to simplify the developer’s task and complicates the user’s task by putting all the elements – description and content – together without any apparent logic. This makes the two difficult or even impossible to distinguish.

The complexity of the OOXML format is linked to its design and was deliberately created to make the format more difficult for non-Microsoft software developers to implement. Compatibility issues are caused by a veritable “maze” of tags used even for the simplest content, which binds users to the Microsoft ecosystem in the first example of standard-based lock-in.

Added to this is the widespread use of convoluted descriptions, such as those relating to dates, which are linked to a bug introduced by Visicalc and still present in Excel 67 years after it was discovered, and the arbitrary separation of content, such as sentences or even words that are broken between two content elements. The format reflects the internal data structures and legacy features of Microsoft Office. It uses non-standard language encodings and units of measurement, as well as inconsistent naming conventions and rules between modules. It also uses abstruse tag names that are difficult to decipher.

The XLSX case

To illustrate the difference in complexity between the ODF and OOXML XML schemas, I created a simple spreadsheet containing dates from my life that are either significant or ironic. These include the date I broke my nose, the date it was repaired, and the date I re-married my wife in Las Vegas to celebrate the 30th anniversary of the marriage with an informal ceremony (a drive-through wedding in a limousine).

This is a screenshot of the spreadsheet:

To perform the analysis, I duplicated and renamed the two files, replacing the original extension with “ZIP”, and then unzipped them to create two folders containing all the files of the respective XML schemas.

The LibreOffice folder contains three subfolders and six files, one of which is called content.xml and immediately catches the eye due to its evocative name. Opening it reveals all the contents, while the other files contain instructions for displaying the spreadsheet correctly.

This is the significant portion of the LibreOffice content.xml file:

This is an XML file of reasonable complexity. Even someone without technical knowledge can identify the contents of the two columns with a little effort. The file is in an understandable format for dates, text strings and tags (table row, table cell, text and date value).

The Microsoft 365 folder contains three subfolders and the [Content_Types].xml file. Opening this file reveals information about the other files, including those in the subfolders. It also shows that the contents should be found in the sheet1.xml file, which is hidden in the worksheets folder, which is hidden in the xl folder. There is no technical reason for this game of hide-and-seek other than to make the internal structure of the XLSX file more complicated.

The significant part of the Microsoft 365 sheet1.xml file is as follows:

It’s an extremely cryptic XML file. Apart from a few tags – col, row, sheetview and sheetdata – the XML schema is completely incomprehensible. Where are the dates? Where are the event descriptions?

They are actually there, but I challenge anyone to find them unless they know that Excel describes them with a sequential number starting from 1 January 1900. For 29 February 1900, it adds one, despite this being a “phantom” day that the programme – which is incompatible with the Gregorian calendar, a standard recognised even by the Chinese and Muslims – stubbornly continues to consider as existing, even though the “leap year bug” was discovered by Bob Bemer in 1958.

Therefore, in Excel, 19948 corresponds to 12 August 1954, but in reality it is 13 August 1954. The other dates are obviously 23,760; 28,813; 29,860; 30,560; 30,933; 31,825; 37,623; 39,550; 40,449; and 41,859. This is intuitive and easy to calculate, and above all it is imposed by the complexity of the document. Bullshit.

However, the mystery of the event descriptions remains. According to sheet1.xml, they do not exist since they do not appear in any way, not even as a reference. It is as if the spreadsheet consisted only of the second column.

So, I return to the [Content_Types].xml file and open the XML files in the order they are listed, searching for them in the subfolders.

<Types xmlns=”http://schemas.openxmlformats.org/package/2006/content-types”>
<Default Extension=”rels” ContentType=”application/vnd.openxmlformats-package.relationships+xml”/>
<Default Extension=”xml” ContentType=”application/xml”/>
<Override PartName=”/xl/workbook.xml” ContentType=”application/vnd.openxmlformats-officedocument.spreadsheetml.sheet.main+xml”/>
<Override PartName=”/docProps/core.xml” ContentType=”application/vnd.openxmlformats-package.core-properties+xml”/>
<Override PartName=”/docProps/app.xml” ContentType=”application/vnd.openxmlformats-officedocument.extended-properties+xml”/>
<Override PartName=”/xl/worksheets/sheet1.xml” ContentType=”application/vnd.openxmlformats-officedocument.spreadsheetml.worksheet+xml”/>
<Override PartName=”/xl/theme/theme1.xml” ContentType=”application/vnd.openxmlformats-officedocument.theme+xml”/>
<Override PartName=”/xl/styles.xml” ContentType=”application/vnd.openxmlformats-officedocument.spreadsheetml.styles+xml”/>
<Override PartName=”/xl/sharedStrings.xml” ContentType=”application/vnd.openxmlformats-officedocument.spreadsheetml.sharedStrings+xml”/>
</Types>

Just as I was about to give up hope, I finally found the event descriptions in the sharedStrings.xml file. The file contains the following:

<sst xmlns=”http://schemas.openxmlformats.org/spreadsheetml/2006/main” count=”13″ uniqueCount=”13″>
<si>

If Sheet1.xml was cryptic, this is downright incomprehensible. I would like to know how the events are related to the dates within the sheet1.xml file through the different tags used in the two files: <t> and <v>. There are no cross-references linking the two elements, and if there are any, I challenge anyone to explain them to me in a way that I can understand and justify the mysterious format of these references.

Unfortunately, the reality is what I have already tried to explain without going into technical detail, as I have done in this post and will do in the next one dedicated to the DOCX case. Microsoft has developed an unnecessarily complex format – if LibreOffice can handle the information more simply, I don’t understand why Microsoft 365 can’t do the same – with the aim of making it extremely difficult to emulate the OOXML format without reverse engineering, which is widely used in some countries.

Furthermore, office suites that use reverse engineering to adopt OOXML as their native format merely help Microsoft to defend its market share by promoting a proprietary format that goes against users’ interests and their right to ownership and control of the content they have developed, generally referred to as digital sovereignty.

Users should learn to protect their rights by choosing an open, standard format such as ODF. This guarantees control over content and all that this entails, including protection of privacy, proper management of sensitive data and the ability to decide what to share and with whom.

This is a format whose development process, features and version are known, and whose description corresponds to what happens on the user’s PC, so even the least technical user can understand when a problem occurs and, in many cases, solve it.

In short, it is the standard document format that we would all like to have, but which only a minority use due to a lack of knowledge about the reality of the OOXML format, and the messianic trust that many have in Microsoft. This leads them to believe that there cannot be a commercial strategy behind the document format that protects the company’s interests at the expense of users.

In the digital world, document formats are essential. Proprietary formats such as Microsoft Word’s DOCX or Excel’s XLSX dominate the workplace, but at the same time they lock users into a specific vendor and its business strategies, which tend to exploit users to the maximum in every way. The Open Document Format (ODF) offers an open, standard alternative that protects users and their privacy, promotes interoperability, long-term access and data ownership.

Migrating documents from proprietary formats to ODF is the solution, and although vendors who rely on proprietary formats – not only Microsoft, but also its freeware clones such as OnlyOffice or WPS Office – do everything they can to prevent it, it is very easy and represents a fundamental step forward for users in terms of privacy and digital sovereignty (i.e., ownership of their own content).

This guide breaks down the migration process to make the transition smooth, efficient and sustainable, both at the individual level (where problems are virtually non-existent) and at the enterprise level, where problems exist due to the lock-in strategies of proprietary formats.

Step 1: Understand ODF and its advantages

• No dependence on a single vendor: freedom to use any compatible software
• Better long-term accessibility, robustness and stability of storage
• Transparency and security, thanks to full compliance with open specifications
• Better interoperability between platforms and tools

Step 2: Document inventory to define conversion priorities and estimate the effort required for migration

• Identification of file types (DOCX, XLSX, PPTX) and their number
• Analysis of documents to distinguish between active (used periodically) documents, those that can be archived and obsolete documents
• Analysis of documents with complex formatting or embedded multimedia content

Step 3: plan the migration workflow

• Convert documents in bulk or gradually as needed?
• Pilot phase with a small group of users to identify any issues with the documents before the mass conversion
• User training on the migration and creation of a support service for conversions and backup management

Step 4: Converting documents to ODF format

• Use the LibreOffice export function (‘Save As’)
• Use batch conversion tools for large volumes (LibreOffice command line scripts)
• Validate converted files to ensure formatting and data integrity
• Back up original files until migration is successfully completed

Step 5: Monitoring the migration

• Updating internal policies to make ODF the default format for document creation and sharing, and to prevent a return to proprietary formats
• Monitoring user feedback and trends in document creation, and resolving issues in a timely manner
• Integrating ODF support into enterprise software platforms, and using automatic conversions where possible

Conclusion

Migrating from proprietary formats to ODF is a strategic move, both individually and for businesses, towards openness, content control and document protection for the future. In a business environment, it requires careful planning and user involvement, but the benefits in terms of flexibility, interoperability and cost savings are well worth the effort.
