A modern, client-side web tool for converting XML files to valid ODT (text document) and ODS (spreadsheet) files. Upload one or more XML files and instantly generate ready-to-use OpenDocument files (ODT/ODS) with syntax-highlighted preview, validation, and batch conversion — all directly in your browser, with no server upload required.
- Batch upload XML files: Convert one or many XML files, generating ODT (text) or ODS (spreadsheet) format as needed.
- Automatic format detection: The tool recognizes whether each XML is ODT or ODS and produces the correct output.
- Advanced XML validation: Checks well-formedness, root tags, required namespaces, and minimal OpenDocument structure for both ODT and ODS.
- Syntax-highlighted preview: See a large, scrollable preview of your XML with color-coded syntax (Prism.js).
- Instant conversion and download: Download each converted file individually, or batch download all as a ZIP archive.
- Automatic companion file generation: Generates
styles.xml,meta.xml, andsettings.xmlautomatically for each document. - Modern Material Design UI: Responsive and attractive interface, with light/dark themes.
- Privacy-first: All processing is done locally in your browser. No data ever leaves your device.
- Delete and reset: Remove individual files or reset the app with one click.
- Accessible and internationalized: All UI and code in English, with accessibility in mind.
- Open the application in your browser (
index.htmlor via GitHub Pages). - Click Upload your XML to select one or more XML files (
content.xmlfor ODT/ODS). - Review validation status, and scrollable syntax-highlighted preview for each file.
- Click Convert to generate and download an
.odtor.odsfile for each XML. - For multiple files, use Convert All to download a ZIP archive containing all OpenDocument files.
- Use Delete to remove individual files, or Delete in the footer to reset all.
- Switch between light/dark themes using the toggle in the top right.
- Frontend only: No backend or server interaction.
- JSZip packs the ODF structure (mimetype, content.xml, styles.xml, meta.xml, settings.xml) into a valid
.odtor.odsfile. - Prism.js provides syntax highlighting for XML previews.
- Material Design Lite supplies Material Design styles for UI components.
- All companion files (
styles.xml,meta.xml,settings.xml) are generated with base templates to ensure document validity.
- Only supports conversion of XML files structured as valid ODT
content.xmlor ODS spreadsheet XML. - No visual/WYSIWYG ODT/ODS editing—preview is text-only.
- Advanced features (custom templates, multi-language, visual editing, support for other ODF formats) are planned for future versions.
- No files are sent to any server.
- All processing and conversion happens in your browser.
- No data is stored beyond your browser session.
