Mbox Viewer

This tool opens and analyzes MBOX mailbox archives in a privacy-preserving, browser-based environment. It reads the MBOX stream and identifies messages, presenting a navigable list with key metadata. It does not modify the source files and operates entirely on the client side.\n\nConceptually, it treats the MBOX as a sequence of messages. For each message, it parses RFC 5322 headers, decodes MIME parts, and attaches attachments with metadata. The result is a structured, queryable view that supports quick inspection and validation.\n\nWho benefits? Developers integrating mail data workflows, IT admins validating archives, QA engineers testing email processing pipelines, and data scientists performing mailbox analytics. The tool’s value lies in streaming parsing, local processing, and straightforward exports without requiring a mail server.\n\nCore features and use cases include: file upload, a message list with summary lines, per-message header and body viewing, MIME decoding, attachment listing, and optional JSON export for automation. Typical tasks: mailbox migration checks, data validation, and forensic data collection from archives.
