Limits and behavior
Local processing. Maximum 10 MB per file, 25 MB total; expanded ZIP contents at most 50 MB and 2,000 entries. Spreadsheet limit: 10,000 cells and 2,000 rows per sheet. Macros are never executed. Originals are unchanged. Cancellation stops active PDF renders and discards stale results; a synchronous library step finishes before the browser can handle cancellation.
Get the outline headings from a DOCX
Read supported Word heading structures and export their labels and levels as JSON. Useful for reviewing a document's outline and sections.
Does a bold paragraph automatically count as a heading?
No. Heading detection uses document structure and styles, not just the visual appearance of bold text.
