OCC

Office Cloc and Count — document metrics, structure extraction, content inspection, and code exploration for real repositories.

Experimental: All features in OCC are currently experimental. This project cannot be considered stable software yet. APIs, output formats, and command interfaces may change between minor versions.

What is this?

OCC started as a way to make office documents visible in the same workflows that already work well for code metrics tools like scc and cloc. It has since grown into a multi-purpose CLI that can:

scan office documents for word/page/sheet/slide metrics
extract document heading structure for navigation and RAG-style use cases
inspect documents (occ doc inspect), spreadsheets (occ sheet inspect), and presentations (occ slide inspect) for metadata, risk flags, and content previews
extract structured table content from documents (occ table inspect)
summarize code metrics through scc
explore JavaScript, TypeScript, and Python repositories with symbol search, call analysis, dependency inspection, and inheritance queries (occ code)

Features

Office document metrics — words, pages, paragraphs, slides, sheets, rows, cells
Seven formats supported — DOCX, XLSX, PPTX, PDF, ODT, ODS, ODP
Document structure extraction — --structure parses heading hierarchy into a navigable tree with dotted section codes (1, 1.1, 1.2, ...)
Document inspection via occ doc inspect — metadata, risk flags, content stats, heading structure, and content preview for DOCX and ODT
Spreadsheet inspection via occ sheet inspect — workbook properties, hidden sheets, names, formulas, links, comments, schema preview, and token estimates for XLSX
Presentation inspection via occ slide inspect — metadata, risk flags, per-slide inventory, and content preview for PPTX and ODP
Table extraction via occ table inspect — structured table content from DOCX, XLSX, PPTX, ODT, and ODP with auto-detected headers, sample row limits, and merged cell support
Code metrics via scc — auto-detects code files and integrates scc output
Code exploration via occ code — JS/TS and Python-first symbol lookup, content search, callers/callees, dependency categories, inheritance, and ambiguity-aware chains
Multiple output modes — grouped by type, per-file breakdown, or JSON
CI-friendly — ASCII-only, no-color mode for pipelines
Flexible filtering — include/exclude extensions, exclude directories, .gitignore-aware
Progress bar — with ETA for large scans
Zero config — auto-downloads scc binary on install, works out of the box

Code Exploration

occ code adds on-demand code exploration without changing the existing document-scan workflow. It builds an in-memory repository graph for each command and does not require a database, daemon, or background indexer.

The first-class support path is JavaScript, TypeScript, and Python. Other languages may be discovered and partially parsed, but the current resolver, fixtures, and output contracts are intentionally optimized around JS/TS and Python behavior.

# Exact symbol lookup
occ code find name Greeter --path test/fixtures/code-explore

# Substring search
occ code find pattern service --path .

# Full-text content search
occ code find content normalize_name --path .

# Outgoing and incoming call analysis
occ code analyze calls bootstrap --path test/fixtures/code-explore
occ code analyze callers createUser --path test/fixtures/code-explore

# Dependency and inheritance inspection
occ code analyze deps src/service --path test/fixtures/code-explore
occ code analyze tree UserService --path test/fixtures/code-explore

# Ambiguity-aware chain analysis
occ code analyze chain ambiguousCaller duplicate --path test/fixtures/code-explore

Highlights of the current code exploration behavior:

Exact, pattern, type, and content search over the repository graph
Call analysis with explicit resolved, ambiguous, and unresolved states
Receiver-aware method resolution for this, super, self, and cls
Dependency analysis grouped into local, external, and unresolved imports
Chain analysis that reports when a path is blocked by ambiguity instead of silently returning nothing
Shared CLI ergonomics with --path, --format, --output, --exclude-dir, and .gitignore support

All occ code commands support --format tabular|json. Most symbol-targeted commands also support --file for disambiguation, and JSON output includes repository metadata, query metadata, results, repository stats, and per-language capability flags.

Document Inspection

occ doc inspect extracts metadata, risk flags, content stats, heading structure, and a content preview from DOCX and ODT documents.

# Document overview with content preview
occ doc inspect report.docx

# Machine-readable payload
occ doc inspect report.docx --format json

# More paragraphs in the preview
occ doc inspect report.docx --sample-paragraphs 10

Current document inspection surfaces:

Document properties — title, author, dates, keywords
Risk flags — comments, tracked changes, hyperlinks, embedded objects, macros, tables, encryption
Content stats — words, pages, paragraphs, characters, tables, images
Heading structure — tree with section codes and depth
Content preview — first N paragraphs with heading detection
Token estimates — preview and full-document token estimates

Spreadsheet Inspection

occ sheet inspect is a lightweight XLSX preflight command aimed at both humans and agents. It helps answer "is this workbook worth reading in depth?" before spending tokens serializing cells or opening the file in Excel.

# Workbook-level summary + per-sheet schema/sample preview
occ sheet inspect finance.xlsx

# Machine-readable inspection payload
occ sheet inspect finance.xlsx --format json

# Narrow to one sheet and reduce preview width
occ sheet inspect finance.xlsx --sheet Revenue --sample-rows 3 --max-columns 8

Current XLSX inspection highlights:

Workbook metadata — file size, workbook properties, custom properties, workbook-scoped names
Sheet inventory — visible / hidden / very hidden sheets, used ranges, cell counts, formula/comment/link counts
Schema preview — detected header row, inferred column types, coverage ratios, example values
Lightweight sampling — small row previews designed for preflight rather than full extraction
Token estimates — sample and full-sheet token estimates to guide downstream agent reads

Presentation Inspection

occ slide inspect provides presentation metadata, risk flags, per-slide inventory, and content previews for PPTX and ODP files.

# Presentation overview with slide preview
occ slide inspect deck.pptx

# Machine-readable payload
occ slide inspect deck.pptx --format json

# Inspect a specific slide
occ slide inspect deck.pptx --slide 3

Current presentation inspection surfaces:

Presentation properties — title, author, dates
Risk flags — comments, speaker notes, hyperlinks, embedded media, animations, macros, charts, tables
Slide inventory — per-slide title, word count, notes, images, tables, charts
Content preview — text preview for sample slides
Token estimates — preview and full-presentation token estimates

Table Extraction

occ table inspect extracts structured table content from DOCX, XLSX, PPTX, ODT, and ODP documents. For AI agents, this is the primary way to read financial summaries, comparison matrices, and data tables without parsing raw XML.

# Extract all tables as JSON
occ table inspect report.docx --format json

# Tabular preview of table content
occ table inspect finance.xlsx

# Extract a specific table
occ table inspect finance.xlsx --table 1

# Limit sample rows
occ table inspect report.docx --sample-rows 5

Current table extraction highlights:

Multi-format support — DOCX (via mammoth HTML), XLSX (via SheetJS), PPTX (from slide XML), ODT and ODP (from content.xml)
Auto-detected headers — first row is treated as headers when values are unique strings
Merged cell support — colspan and rowspan are preserved in the output
Sample row limits — configurable maximum rows per table (default: 20)
Table filtering — extract a specific table by index with --table N
Token estimates — per-table and total token estimates
PDF graceful degradation — returns empty tables with an informative note instead of unreliable heuristic output

Why OCC?

Tools like scc, cloc, and tokei give you instant visibility into codebases — lines, languages, complexity. But most projects also contain Word documents, PDFs, spreadsheets, and presentations that are invisible to these tools. OCC fills that gap.

For Humans

Project audits — instantly see how much documentation lives alongside your code: total word counts, page counts, spreadsheet sizes, and presentation lengths
Tracking documentation growth — run OCC in CI to monitor how documentation scales over time, catch bloat early, or enforce minimums
Onboarding — new team members get a quick sense of a project's documentation footprint before diving in
Migration planning — when moving to a new platform, know exactly what you're dealing with across hundreds of files and formats

For AI Agents

Context budgeting — LLMs have finite context windows. OCC's word and page counts let agents estimate how much of a document set they can ingest before hitting token limits
Prioritization — an agent deciding which documents to read can use OCC's JSON output to rank files by size, word count, or type, focusing on the most relevant content first
RAG chunk mapping — --structure --format json outputs heading trees with character offsets, enabling chunk-to-section mapping, scoped retrieval, and citation paths in RAG pipelines
Document triage — occ doc inspect --format json surfaces risk flags, content stats, structure, and token estimates before an agent reads the full document
Spreadsheet triage — occ sheet inspect --format json exposes sheet visibility, formulas, links, comments, schema hints, and token estimates before an agent expands workbook contents
Presentation triage — occ slide inspect --format json provides slide inventory, risk flags, and content previews for quick assessment
Table extraction — occ table inspect --format json extracts structured table data (headers, rows, cells) from documents, giving agents direct access to tabular content without parsing raw XML
Repository mapping — agents exploring an unfamiliar codebase can combine occ --format json for document inventory with occ code ... --format json for symbol and relationship data
Pipeline integration — JSON output pipes directly into agent toolchains for automated document analysis, summarization, or compliance checking

How It Works

OCC is written in TypeScript and uses fast-glob for file discovery, dispatches to format-specific parsers (mammoth for DOCX, pdf-parse for PDF, SheetJS for XLSX, JSZip + officeparser for PPTX/ODF), aggregates metrics, and renders output via cli-table3. For code metrics, it shells out to a vendored scc binary (auto-downloaded during npm install, with PATH fallback).

For structure extraction (--structure), documents are first converted to markdown (mammoth + turndown for DOCX, pdf-parse with page markers for PDF), then headers are extracted and assembled into a tree with dotted section codes.

For occ code, OCC builds an in-memory code graph on demand. JavaScript and TypeScript are parsed with the TypeScript compiler API, Python uses a language-specific parser, and the query engine resolves symbols, imports, calls, inheritance, ambiguities, and dependency categories without a persistent database.
