  • LibreOffice allows reading and editing .docx documents, although visual discrepancies may arise depending on the complexity of the file.
  • Using built-in conversion tools or saving in ODF format minimizes data loss between different office suites.
  • Manual review after opening external files is essential to correct alignment, border, or style errors.

Sometimes, when we try to open a Microsoft Word document using LibreOffice, we find that the layout isn't exactly the same. This is quite common, because although LibreOffice can read .docx files , there are slight differences in how each program interprets the format's code, which can lead to those annoying visual glitches.

Don't worry if you see things shifting or strange borders appearing; it's not that your computer is broken, but rather a compatibility issue between software suites . In this article, we'll take an in-depth look at how to manage these files so your documents look flawless, regardless of the program you use to edit them.

The format warning when saving files

It's very common that when trying to save a document in .docx format from LibreOffice, or a .odt file from Word, a message appears warning that the file may contain content that cannot be saved in the selected format. This happens because some advanced features of one program don't have an exact equivalent in the other.

In most cases, if the document is simple, you can ignore the warning. However, if you're working with complex graphic elements , such as nested tables or specific underlines, the formatting may be significantly altered. For example, some users have reported problems when trying to remove color highlights created in Writer, which become impossible to delete when opened in Word , creating a frustrating editing conflict.

How to convert Word files to LibreOffice step by step

If you want to avoid corrupting the formatting, the best solution is to perform a formal file conversion. LibreOffice includes a dedicated tool for this that is much more robust than simply opening the document.

  • Installation and access: The first thing you need is to have LibreOffice installed. Once it's open, you don't need to create a new document; go directly to the top menu.
  • Using the Assistant: Head to the route File > Assistants > Document ConverterHere you will need to select the Microsoft Office Files option and, specifically, Word files.
  • Folder settings: An important detail is that the wizard asks you to select an entire folder, not a single file. To avoid converting documents you don't want to, it's best to... put the file in its own folder before starting the process.
  • Final revision: Once the program finishes the conversion to the format .odtIt's essential to open the file and take a look. It's normal to find some residual edges or line breaks that shouldn't be there, so manual cleanup is the final step required.

Quick conversion alternatives

If you don't want to use the built-in wizard, there are other quite effective ways to prevent the document from becoming corrupted. A very natural option is to open the file in the online version of Word (which is free) and use the " Save as Open Document Type" option . This generates an .odt file that LibreOffice handles much better.

For those who need to reverse the process, that is, convert from LibreOffice to Word, simply use the Save As option and choose the Word 2007-365 (.docx) format . If for some reason the result is not as expected, there are external converters like Online-Convert that can help clean the file's code before opening it in the Microsoft suite.

Tips for avoiding design problems

To avoid unpleasant surprises with formatting, the smartest thing to do is use compatible templates . There are professional resources that are already optimized to make the transition between programs almost seamless, especially for documents like resumes or invoices.

Remember that the .odt (Open Document Text) format is the native standard for LibreOffice and is the most secure for preventing data loss. If you're collaborating with someone who uses Word, it's best to finalize the design in a single program and only export to .docx at the end of the process , thus avoiding the constant saving in different formats that often corrupts the text structure.

Managing interoperability between LibreOffice and Microsoft Word requires some patience and, above all, knowing how to leverage conversion tools and the open format. Although rendering differences can cause visual errors, using built-in wizards and manual review ensures that any professional document maintains its integrity regardless of the software used.
