About this pptx embedded media extractor
Extract every embedded file under ppt/media/ from a local PPTX, including nested folders. Preserve relative paths and exact file bytes in the downloaded ZIP; no image, audio or video re-encoding Parses and structures office document payloads locally in memory without transmitting private company files to external servers.
Document parsing & data extraction pipeline
Inspects and extracts deep metadata from Microsoft Office OpenXML document containers (DOCX, PPTX, XLSX) in compliance with ECMA-376 and ISO/IEC 29500 standards. Decompresses ZIP packages in browser memory to parse XML DOM trees: Word comment parts (word/comments.xml, commentsExtended.xml), revision marks, PowerPoint master font themes (ppt/presentation.xml, ppt/theme/theme1.xml), and embedded media archives. Exports comment threads and font audits directly to structured Excel workbooks (XLSX).

File size & structure constraints
Operational constraints and validation boundaries: Nonempty PPTX strictly below 300000000 bytes, at most 10,000 ZIP entries and 512 MiB of expanded media. Only existing embedded package bytes are copied; linked assets, slide/page usage and pre-insertion originals are not reconstructed. Nested media paths remain nested, preventing duplicate basenames from overwriting each other. Duplicate ZIP names and unsafe relative paths are rejected. A main document entry is required, but this is not full OpenXML validation or media decoding. Encrypted packages are unsupported. File sizes, hashes and ZIP contents can be checked; desktop apps, high-resolution photography suites and near-limit memory behavior remain unverified.
PPTX Embedded Media Extractor parses structured OpenXML and PDF data locally. Review exported tables or sheets against original files.
Zero-upload document security boundary
File buffers and document assets in PPTX Embedded Media Extractor are processed in-memory via local browser APIs with zero file uploads to CZOA servers.
