Archive modernization
Upgrade historical business documents before moving them into a modern archive, records system, or cloud storage convention.
AWS Marketplace SaaS · API v1
Modernize legacy Office files before migration, automation, or AI processing
CoreNova converts valid Microsoft Office 97-2003 DOC, PPT, and XLS files into modern DOCX, PPTX, and XLSX packages through a small asynchronous API.
Simple contract: submit one file, receive a task ID, query the task, then download the validated result. Only successful conversions are metered.
Problems this API solves
Application upload compatibility
Accept legacy files from customers and normalize them before handing content to modern backend libraries.
Cloud migration preparation
Standardize mixed Office 97-2003 collections before a Microsoft 365, SharePoint, document-management, or data-lake migration.
AI and RAG preprocessing
Remove a legacy binary-format dependency before downstream parsing, structure extraction, chunking, embedding, and indexing.
Supported conversions
| Source | Result | Metering dimension | Typical downstream use |
|---|---|---|---|
.doc | .docx | DocConversion | Document management, text and table parsing, knowledge archives |
.ppt | .pptx | PptConversion | Slide analysis, presentation migration, per-slide extraction |
.xls | .xlsx | XlsConversion | Worksheet parsing, tabular normalization, analytics preparation |
How it works
Subscribe and register. Purchase through AWS Marketplace, choose Set Up Your Account, and create a one-time API key.
Upload one legacy file. Send multipart form data to
POST /v1/conversions.Query the task. Poll
GET /v1/conversions/{task_id} until it succeeds or fails.Download and continue. Retrieve the short-lived result, validate it against your business requirements, then pass it to the next system.
Designed for a narrow job
This service modernizes Office file formats. It does not perform OCR, semantic chunking, embeddings, vector indexing, direct SharePoint migration, or RAG retrieval. Those functions belong in the downstream processing layer.
Validate representative files: conversion targets structural compatibility, not guaranteed pixel-perfect equivalence. Test documents containing critical fonts, charts, formulas, floating objects, headers, footers, and embedded content before a large migration.
Service behavior
- Maximum source file size: 4 MiB.
- Inputs are deleted after processing; successful results remain available for approximately 30 minutes.
- Macros are not executed, and XLS VBA preservation is disabled.
- Encrypted, corrupted, disguised, and documented unsupported files are rejected.
- Authentication failures, failed tasks, status queries, downloads, and idempotent replays are not metered.
