- Splitting up (shredding) a DOCX or PPTX file into multiple files, and combining multiple DOCX / PPTX files into a single file.
- High fidelity conversion of DOCX => HTML/CSS and HTML/CSS => DOCX.
- Extraction of data from XLSX.
- Searching and replacing content in DOCX / PPTX using regular expressions.
- Updating cached data and embedded spreadsheets for charts in DOCX / PPTX.
- Document modification, such as removing tracked revisions or removing unacceptable content from documents.
