SMath Studio to ODT converter

A fully proprietary-free document chain looks like this: SMath does the calculation, LibreOffice handles the layout, the deliverable lands in the open ISO/IEC 26300 (ODF) standard. This step bridges the two free tools — every equation becomes a native LibreOffice Math object, unit annotations survive, and plots come across as scalable graphics. The resulting .odt opens in Russian government-issued office suites (МойОфис, Р7-Офис) per the import-substitution mandate without losing editability.

How it works

  1. 1
    Upload your SMath Studio file

    Drag a .sm or .smz file (up to 50 MB) onto the upload zone. Files are encrypted in transit.

  2. 2
    Select ODT as the output format

    Choose "ODT" in the format selector and click Convert. The server writes ODF formula objects — typically 3–5 seconds.

  3. 3
    Download .odt and open in LibreOffice

    The file is available for 5 minutes. Open in LibreOffice Writer — formulas are editable via the built-in Math editor.

Frequently asked questions

Does this give a fully free-software-only conversion path?

Yes. SMath Studio is free and open, the converter operates anonymously without licenses, and LibreOffice Writer opens .odt natively. Microsoft Word and Mathcad are not needed at any step.

Is the ODT output compliant with the ODF specification?

Yes. The converter generates .odt conforming to ODF 1.3 (ISO/IEC 26300). The file opens in LibreOffice, OpenOffice, and Google Docs (with conversion). Basic ODF validation passes without errors.

Do I need SMath Studio installed?

No. The converter runs server-side. You only need a browser and a .sm or .smz file.

Are formulas editable in LibreOffice Math?

Yes. Double-click a formula in LibreOffice Writer — the built-in Math editor opens and lets you modify any expression.
