Convert FODS to XML

Understanding FODS and XML file formats

FODS (Flat OpenDocument Spreadsheet) is an XML-based spreadsheet file format used by LibreOffice Calc and OpenOffice Calc. It stores spreadsheet data in a flat XML structure, making it easy to read and edit with text editors. XML (eXtensible Markup Language) is a flexible, widely-used markup language for storing and transporting data in a structured, human-readable format. While FODS is a specific XML schema for spreadsheets, generic XML files can represent any structured data.

Why convert FODS to XML?

Converting a FODS file to a generic XML format can be useful for data integration, migration, or custom processing. This allows spreadsheet data to be used in applications that require a more general XML structure or to facilitate data exchange between different systems.

How to convert FODS to XML

Since FODS is already an XML-based format, conversion typically involves transforming the FODS structure into a custom or simplified XML schema. This can be done using XSLT (Extensible Stylesheet Language Transformations) or specialized software tools.

Recommended software for FODS to XML conversion

• LibreOffice Calc: Open the FODS file, then use File → Save As to export to other spreadsheet formats (such as CSV or ODS), which can then be converted to XML using additional tools or scripts.
• Oxygen XML Editor: Allows you to open FODS files and apply XSLT transformations to convert the data into your desired XML schema.
• Custom XSLT scripts: For advanced users, writing an XSLT stylesheet to transform FODS XML into a custom XML format is a flexible solution.

Step-by-step conversion using LibreOffice Calc and XSLT

1. Open your FODS file in LibreOffice Calc.
2. Save the file as FODS if not already in that format.
3. Open the FODS file in a text or XML editor.
4. Apply an XSLT transformation to convert the FODS structure to your desired XML schema.
5. Save the output as an XML file.

Tips for successful conversion

• Understand the structure of both FODS and your target XML schema before converting.
• Use validation tools to ensure the resulting XML is well-formed and meets your requirements.
• For large or complex spreadsheets, consider automating the process with scripts or batch tools.
