Comparable File Format

LibreOffice offers a suite of tools that are popular alternatives to Microsoft Office suite. Although the features offered are very similar, not all features are one-to-one and the file formats produced are different. For comparison, refer to Differences between the OpenDocument Text (.odt) format and the Word (.docx) format. LEADTOOLS supports LibreOffice ODFs for the following Operating Systems:
