Instructions for translators

Translation Guidelines for ONLYOFFICE Web Apps

String format

  • Strings use positional placeholders like {0}, {1}, {2}. Do NOT translate or remove them — they are replaced with values at runtime.
  • Some strings contain HTML tags (<br>, <b>, </b>, <a>, etc.). Preserve all HTML tags exactly as they appear in the source.

Key naming conventions

  • Keys prefixed with DE. belong to Document Editor
  • Keys prefixed with PE. belong to Presentation Editor
  • Keys prefixed with SE. belong to Spreadsheet Editor
  • Keys prefixed with PDFE. belong to PDF Editor
  • Keys prefixed with VE. belong to Visio Editor
  • Keys prefixed with Common. are shared across editors.
  • Some shared keys have editor-specific variants with a suffix (e.g., warnUpdateExternalDataDE vs warnUpdateExternalDataPE) — translate each according to its editor context.
  • This may help you choose the right context for ambiguous terms.

General rules

  • Keep translations concise — UI space is limited, especially in toolbar buttons and menus.
  • Use formal tone (e.g., "vous" in French, "Sie" in German, "Вы" in Russian) unless your language community prefers informal.
  • Do not translate product names: ONLYOFFICE, Document Editor, Spreadsheet Editor, Presentation Editor, PDF Editor, Visio Editor.
  • Keyboard shortcuts (e.g., Ctrl+C, Shift+Enter) should follow platform conventions for your locale but keep the key names recognizable.
