Apryse Office SDK Features


Get accurate and reliable rendering of DOCX, XLSX, PPTX, and legacy format documents in your browser via any JavaScript framework. Integrate Office viewing on low-code platforms such as Salesforce, Mendix, Appian, and others.


Annotation and Collaboration

Empower users with real-time Office collaboration. Standardize review and approval workflows for markups, comments, stamps, and countless other custom annotations.


Bring high-fidelity conversion for PDF to Office (and vice versa) to your application and make broken formatting in converted PDFs a distant memory.


Semantic Comparison

Compare two documents side by side to highlight edits, insertions, and deletions. Instead of indicating changes by individual characters, semantic comparison intelligently and intuitively highlights changes by words, sentences, or paragraphs, even across pages.

DOCX Editing

Edit and create DOCX files client-side: Write and edit text, apply styling, adjust fonts and sizes, or add bulleted and numbered lists. Eliminate post-edit formatting inconsistencies with native DOCX editing, producing true WYSIWYG output quality across all Word processors.


True Redaction

Permanently remove sensitive information from converted Office documents as part of a single, customizable workflow. Search and redact finds defined strings, such as personally identifiable information, so you can redact it in seconds while keeping documents searchable.

Time to make work better and life simpler.
