We are thrilled to announce the release of officeParser v7.0.0, a milestone version that redefines document processing for the AI era.

Since 2019, officeParser has been a trusted utility for simple text extraction. Today, we are evolving into a comprehensive document knowledge engine designed specifically for the next generation of AI-first infrastructure.

officeParser is now a dual-purpose engine. Beyond parsing, you can now generate high-fidelity outputs from the unified Office AST.

• Universal Serialization: Transform any document into Markdown, HTML, CSV, RTF, or Layout-Aware Text.
• The StyleMapper Engine: A new semantic translation layer that preserves formatting (bold, italic, colors, tables) across all output formats using a robust DSL.

v7.0.0 introduces OfficeConverter, our new flagship API for one-step document transformations.

• Streamlined convert: A single method to go from any source file to any target format with automatic configuration sync.
• Fluent AST Interface: The AST now features an asynchronous .to() method, allowing you to chain transformations effortlessly: await ast.to('markdown'), await ast.to('html'), or await ast.to('chunks').

We’ve built the "Knowledge Bridge" required to turn messy, unstructured office files into high-precision data for your AI agents.

• Native RAG Chunking Suite: No more external dependencies. Split documents using fixed-size (recursive), structural (hierarchy-aware), or semantic strategies.
• Metadata-Aware: Every chunk retains its structural context, ensuring your Vector DB retrieval is more accurate than ever.

• New Parser Extensions: We now natively ingest CSV, HTML, and Markdown, treating them as first-class citizens in our unified Office AST.
• Redesigned AST: Support for complex table structures (vertical/horizontal merging), nested lists, and format-specific metadata.

• Extreme Speedups: We eliminated $O(n^2)$ bottlenecks in RTF parsing and achieved up to 23x speedups in OpenOffice (ODP) processing.
• Memory Efficiency: Re-engineered Excel parsing with matchAll iteration, preventing execution stalls on massive spreadsheets.
• DOCX Fidelity: Full support for w:vMerge and w:gridSpan, ensuring table structures are preserved exactly as they appear in Word.

npm install officeparser

The new API makes complex transformations trivial:

const { parseOffice, convert } = require('officeparser');
// Option 1: One-step conversion (High-level)
// Convert any file to Markdown, HTML, CSV, etc. in one line.
const { value } = await convert('proposal.docx', 'md');
console.log(value); // The generated Markdown string
// Option 2: Parse once, convert many (Fluent API)
// Ideal for multi-format export or RAG chunking.
const ast = await parseOffice('data.xlsx');
const { value: html } = await ast.to('html');
const { value: chunks } = await ast.to('chunks');

Since 2019, officeParser has been maintained by a single person as a voluntary project, growing from a simple utility to a critical piece of infrastructure with over 10 million downloads and 300,000+ weekly installations.

As we pivot towards the "Super-Tool" era, I am seeking professional sustainability to fund the next phase of the roadmap:

• Core Sustainability: Maintaining 100% test coverage and dependency health for my global user base.
• Multi-Runtime Excellence: Official support and drivers for Bun, Deno, and Edge (Cloudflare Workers, Vercel).
• Enterprise Connectivity: High-performance connectors for LangChain, LlamaIndex, and Haystack, alongside intelligent chart-to-JSON extraction.

If officeParser powers your production workflows or AI pipelines, please consider supporting its development:

• #16675 11d4592 Thanks @ascorbic! - Fixes a regression where Astro.cache was undefined when experimental.cache was not configured.

  The previous documented behavior is for Astro.cache to always be defined as a no-op shim: cache.set() warns once, cache.invalidate() throws and cache.enabled can be used to gate. This allows library and user code can call cache methods without conditional checks. The cache provider registration was being gated at the call site on experimental.cache being configured, which meant the disabled shim branch inside the provider was unreachable and the Astro.cache getter was never attached to the context.
