TDF Annual Report 2024

The Annual Report of The Document Foundation describes the foundation’s activities and projects, especially in regard to LibreOffice and the Document Liberation Project.

We’ve been posting sections of the 2024 report here on the blog, and now the full version is available in PDF format on TDF’s Nextcloud server in two different versions: low resolution (6.6MB) and high resolution (56.2MB). The Annual Report is based on the German version presented to the authorities.

The document has been entirely created with free open source software: written contents have obviously been developed with LibreOffice Writer (desktop) and collaboratively modified with LibreOffice Writer (online), charts have been created with LibreOffice Calc and prepared for publishing with LibreOffice Draw, drawings and tables have been developed or modified (from legacy PDF originals) with LibreOffice Draw, images have been prepared for publishing with GIMP, and the layout has been created with Scribus based on the existing templates.

We at The Document Foundation are very grateful to all contributors to our projects and communities in 2024 – none of this would be possible without you!

How to resolve common compatibility issues with ODF files

Troubleshooting opening, formatting, and data loss issues with Open Document Format files

ODF files are great for sharing documents across multiple platforms, but they don’t always work perfectly, especially when using Microsoft Office or other software based on proprietary formats. If you’ve encountered problems opening, editing, or preserving the formatting of .odt, .ods, or .odp files, you’re not alone.

Here’s an overview of the most common compatibility issues with ODF files, along with their solutions.

1. The ODF file does not open in Microsoft Office

Opening an .odt file with Word or an .ods file with Excel is unsuccessful, and the file opens with formatting errors. Microsoft Office supports ODF, but not always correctly, and although support has improved in recent versions, files continue to have difficulties with some features.

There are two solutions: updating Microsoft Office, as compatibility improves with each new version; and converting with LibreOffice, which natively handles ODF files and, in compatibility mode, .docx and .xlsx files much better than Microsoft Office does with .odt and .ods files.

2. Formatting changes during transfer between suites

A file may appear perfect in LibreOffice, but when opened in Microsoft Office, the layout, fonts or spacing may change. This happens because the two software programmes interpret elements such as text boxes, tables and styles differently. Line spacing and bullet points may also change.

The solution is to use simple formatting in all cases where the file is shared between multiple office suites, avoiding complex layouts, unusual fonts and embedded elements. If formatting is more important than editability, you can use PDF format for the final version.

3. Images and graphics disappear or become corrupted

Images or graphics embedded in the document disappear, become distorted or can no longer be edited when opened with other software. This is because their formats are specific to the software that created the file – and therefore proprietary – and not standard, as is often the case with Microsoft Office.

The solution is to use standard formats, such as PNG or JPG for bitmap images, and SVG for vector images. In some cases, it is advisable to convert images before embedding them in the document and, if possible, simplify them (without altering them).

4. Macros and scripts do not work

Macros written in one suite do not work (or cause errors) in another. This is a known problem, linked to the fact that the scripting languages – Microsoft Office VBA and LibreOffice Basic – are proprietary and therefore incompatible with each other.

The solution is to avoid macros when sharing files, and if it is really impossible to do without them, you need to rewrite the scripts for each platform, using the respective languages. Unfortunately, there are no shortcuts or interoperable solutions.

5. Some data is lost when saving in proprietary format

In some cases, quite sporadic, saving an ODF file in proprietary format causes data loss. Unfortunately, this is a problem due to the artificial complexity of Microsoft Office proprietary files, which use an XML syntax that is very different from the standard in order to limit file interoperability. The solution is to always keep a copy of the original ODF file, because the format is much more robust and, above all, can be recovered by the user in case of file corruption.

In these cases, LibreOffice is the user’s best friend, because it handles ODF files natively and exports clean .docx, .xlsx and .pptx files with XML syntax that never reaches the level of artificial complexity of Microsoft Office.

Final considerations

ODF is the best open standard format for office documents. It is robust and flexible and was created to protect users’ rights thanks to its features that make it independent, interoperable, neutral and perennial. However, this does not mean that it is perfect and easy for developers to implement when the software has not been developed with the same objectives as LibreOffice, as in the case of Microsoft Office.

If problems arise, the key is to know what each office suite can and cannot handle, bearing in mind that LibreOffice was developed with the aim of protecting the interests of users, while proprietary suites were developed to protect the commercial interests of vendors.

The secret is to keep things simple, focusing on the content rather than the appearance of the document. When in doubt, always use the safest format, which is ODF.

The Document Foundation announces LibreOffice 25.2.6

Berlin, 8 September 2025 – The Document Foundation announces the release of LibreOffice 25.2.6, the sixth maintenance release of the LibreOffice 25.2 family, available for download at www.libreoffice.org/download [1].

LibreOffice 25.2.6 is based on the LibreOffice Technology, which enables the development of desktop, mobile and cloud versions – either from TDF or from the ecosystem – that fully support the two ISO standards for document formats: the open ODF or Open Document Format (ODT, ODS and ODP) and the closed and proprietary Microsoft OOXML (DOCX, XLSX and PPTX).

Products based on the LibreOffice Technology are available for all major desktop operating systems (Windows, macOS, Linux and ChromeOS), mobile platforms (Android and iOS) and the cloud.

For enterprise-class deployments, TDF recommends a LibreOffice Enterprise optimized version from one of the ecosystem companies, with dedicated value-added features and other benefits such as SLAs and security patch backports for three to five years (www.libreoffice.org/download/libreoffice-in-business/).

English manuals for the LibreOffice 25.2 family are available for download at https://books.libreoffice.org/en/. End users can get first-level technical support from volunteers on the user mailing lists and the Ask LibreOffice website: ask.libreoffice.org.

Downloading LibreOffice

All available versions of LibreOffice for the desktop can be downloaded from the same website: www.libreoffice.org/download/.

LibreOffice users, free software advocates and community members can support The Document Foundation and the LibreOffice project by making a donation: https://www.libreoffice.org/donate.

Announcement of LibreOffice 25.8.1

Berlin, 29 August 2025 – LibreOffice 25.8.1, the first minor release of the free, volunteer-supported office suite for personal productivity in office environments, is now available at https://www.libreoffice.org/download for Windows, MacOS and Linux.

The release includes close to 100 bug and regression fixes over LibreOffice 25.8 [1] to improve the stability and robustness of the software. In particular, the release resolves the application crash issue related to the NoteBookBar UI option, and several bugs related to opening documents in Microsoft proprietary format.

LibreOffice is the only office suite with a feature set comparable to the market leader. It also offers a range of interface options to suit all user habits, from traditional to modern, and makes the most of different screen form factors by optimising the space available on the desktop to put the maximum number of features just a click or two away.

For users who don’t need the latest features and prefer a version that has undergone more testing and bug fixing, The Document Foundation maintains the LibreOffice 25.2 family, which includes several months of back-ported fixes. The current release is LibreOffice 25.2.5.

The Document Foundation does not provide technical support for users, although they can get it from volunteers on user mailing lists and the Ask LibreOffice website: https://ask.libreoffice.org

LibreOffice users, free software advocates and community members can support the Document Foundation by making a donation at https://www.libreoffice.org/donate.

One week to the LibreOffice Conference in Budapest

The LibreOffice Conference will start in a week from today with the Community Meeting, at the Faculty of Informatics of ELTE (Eötvös Loránd University) in Pázmány Péter stny. 1/C, 1117 Budapest. The building is just in front of the Danube on the historic Buda side, and can be easily reached either by walking or by public transportation from the city center in Pest, where you can find the majority of hotels and restaurants.

To reach the city from the airport, take Bus 100E which goes directly to downtown (Deák Ferenc tér). Buy and validate tickets directly on the bus using your bank card for the Budapest Pay&GO service. bkk.hu/en/travel-information/airport-express/

Inside the city use public transport (BKK): metro, tram, bus. Buy tickets from purple machines or use the BudapestGO mobile app (iOS, Android). bkk.hu/en/ The best deal is a 24h / 72h travel pass, which does not need validation at each trip. IMPORTANT: the travel pass is not valid for the airport bus!

Currency is Hungarian Forint (HUF). Cards are accepted almost everywhere, but also you may need some Forint cash from Correct Change, Exclusive Change, or Gold Change. Avoid Euronet ATMs, use instead ATMs at major Hungarian banks like OTP, K&H, Erste, UniCredit, Raiffeisen, or CIB.

Time zone is CEST (UTC+2). Electricity is 230V, with standard European plug.

The Survival Guide with more information will soon be available on the Conference website.

In memory of Juan Carlos Sanz

Juan Carlos Sanz, a long time contributor to OpenOffice and LibreOffice, and a TDF Member, passed away last Friday, August 22. He has been contributing to documentation and localization in Spanish, and has been active in the forums to help LibreOffice users as much as he could.

In July 2022, Juan Carlos was interviewed by Mike Saunders for the Community Member Monday. In 2022, he also attended the LibreOffice Conference in Milan (2022) and Bucharest (2023).
