Use it when Word or PowerPoint stores the wrong proofing or spell-check language for the text. Processing stays in the browser across 17 formats; the main OOXML variants, ODT/ODP/ODS and RTF now have representative manual validation in their corresponding applications.

Word OOXML
DOCX, DOCM, DOTX and DOTM with effective-language resolution from text, styles, paragraphs and defaults; the variants passed manual open/repair checks.
02
PowerPoint OOXML
PPTX, PPTM, POTX, POTM, PPSX and PPSM with auditing across slides, notes, charts and SmartArt.
03

RTF
Audit and repair through \langN and \deflangN, with automated coverage and representative manual validation completed in Microsoft Word.
05
Smart Fix
Preselects only high-confidence non-Catalan/Valencian mismatches; medium-confidence or ambiguous cases require explicit review.
