Reader and Document Extraction

Edit on GitHub

Detect formats and extract normalized documents, chunks, hierarchy, tables, visuals, assets, and ingest results.

Reader is the cross-format path for search, review, ingestion, migration, and AI preparation. Its 13 exported commands expose the normalized OfficeIMO.Reader model without forcing the caller to switch on every native document type.

What Reader returns

  • Get-OfficeDocument returns the normalized document envelope.
  • Get-OfficeDocumentDetection reports detected format and routing evidence.
  • Get-OfficeDocumentCapability explains the selected adapter's supported output.
  • Get-OfficeDocumentHierarchy exposes section and structural relationships.
  • Get-OfficeDocumentChunk returns bounded text/content chunks.
  • Get-OfficeDocumentStructured exposes structured content.
  • Get-OfficeDocumentTable, Get-OfficeDocumentVisual, and Get-OfficeDocumentAsset return non-text material explicitly.
  • Get-OfficeDocumentBatch and Get-OfficeDocumentIngest support pipeline-scale processing.
  • Search-OfficeDocument searches the normalized result.

Choose Reader versus a native family

Use Reader when downstream behavior is common across file formats: indexing, chunking, extraction, discovery, classification, previews, and bulk ingest. Use Word, Excel, PowerPoint, PDF, Visio, or another native family when the script must modify format-specific objects and preserve their native semantics.

Reader adapters are modular. A deployment can carry only the adapters it needs, while broader presets compose multiple local formats. Optional OCR, web, and process-backed integrations have separate dependency and trust boundaries.

Operational pattern

Detect first, inspect capabilities, extract the required surfaces, and record warnings/provenance with the output. Do not silently reduce a document to plain text when tables, visuals, or assets matter to the consumer.
