Policy and contract archives
Normalize legacy documents before classification, retention review, or import into a document-management system.
Word modernization
Convert DOC to DOCX before archive, migration, or document parsing
Word 97-2003 DOC files can remain in contracts, procedures, reports, correspondence, and shared-drive archives long after applications have moved to modern cloud environments. The API creates a modern DOCX package without requiring Microsoft Word or Windows desktop automation on the calling server.
Good-fit scenarios
Knowledge-base preparation
Create a modern intermediate document before extracting headings, paragraphs, lists, and tables for AI search or RAG.
Customer upload support
Allow a server-side application to accept DOC uploads even when its normal parser supports DOCX more reliably.
Office automation replacement
Remove a Windows COM or installed-Word dependency from a backend conversion stage.
Recommended pipeline
DOC→CoreNova API→DOCX→validate→archive or parse
For RAG, continue by extracting meaningful document elements, attaching source metadata, chunking by headings or sections, generating embeddings, and indexing the chunks. DOCX itself is an intermediate format, not a semantic chunk format.

- Open representative results in the applications used by your customers.
- Compare page count, headings, tables, lists, images, headers, footers, and page breaks.
- Verify fonts are available in the destination environment.
- Confirm downstream parsers read the DOCX structure you depend on.
- Keep the source DOC according to your archive and legal-retention policy.
Boundary: the API does not execute macros and does not guarantee pixel-perfect layout. Encrypted, corrupted, disguised, or unsupported legacy variants fail without metering.
