Zip Extractor

This tool inspects ZIP archives by reading the central directory structure in the uploaded file, listing all entries without extracting file data. It provides an index of files and folders, including their path, name, size, compressed size, type, and modification time. The intended users are developers building data pipelines, QA engineers validating package integrity, IT admins auditing transfers, and data scientists needing quick visibility into archives before processing. It supports ZIP64 to handle large archives and nested directories.
Core capabilities include optional filters by file extension, a cap on displayed entries, and the ability to export the resulting index as JSON or CSV for automation. The tool also computes simple metrics such as per-file compression ratios and a high-level archive summary (total files, total uncompressed and compressed sizes). All calculations run in memory in the browser or server, depending on deployment, avoiding any data extraction.
Use cases span validation of software bundles, preflight checks for data transfers, forensic checks in incident response, and educational demonstrations of ZIP structure. The approach is non-destructive and fast, returning a structured dataset that downstream systems can ingest. By focusing on metadata rather than content, it enables rapid decision making and integration with data catalogs, CI pipelines, or documentation workflows.
Note: The tool preserves privacy by not extracting contents and does not decrypt password-protected archives; encrypted archives may return an error or a partial index. It supports standard ZIP and ZIP64 formats; it does not handle RAR or 7z archives.
