Email and Archive Viewers

Mailbox Formats and Chat Exports

Eleven readers covering every mail archive that lands in a migration or a handover.

PST Viewer Outlook's mailbox file. Walk the folder tree without a mail profile or a licence. OST Viewer The cached copy Outlook leaves behind, readable even when the account is gone. MBOX Viewer What Thunderbird and Apple Mail export to, often several gigabytes at a time. EML Viewer A single message saved to disk, usually as an attachment. Opens with full headers. MSG Viewer Outlook's own message format, which is unreadable on a Mac until you open it here. OLM Viewer What Outlook for Mac exports. Windows Outlook will not touch the format. DBX Viewer Outlook Express stores from the Windows XP era, still turning up in handovers. Gmail Takeout Viewer The mbox bundle Google hands you. Search it before committing to a migration. Skype Chat Viewer Conversation history from a Skype export, laid out as a readable thread. MBOX Counter Answers how big is this archive before you start a conversion. PST Analyzer Shows which folders are bloating a PST and which date ranges you can cut.
Document and Scan Viewers

Office Files, PDFs and Paper Scans

Six readers for the formats that arrive as email attachments and refuse to open.

PDF Viewer Read and search a PDF without a browser plugin or a desktop reader. DOCX Viewer Open a Word file when Word is not installed and the formatting still matters. PPTX Viewer Step through a deck without PowerPoint and without a Google account. XPS Viewer Microsoft's print format, which is awkward to open almost anywhere else. TIFF Viewer Multi-page scans and fax archives, paged through one image at a time. Markdown File Viewer A .md file rendered the way it will publish, not as raw syntax.
Data File Viewers

Structured Data You Can Actually Read

Three readers for files that open as a wall of text in a plain editor.

CSV Viewer Row counts too large for a spreadsheet to open comfortably, sorted and filtered. JSON Viewer Nested API output as a tree you can collapse instead of a single long line. XML Viewer Config files and feeds with the node hierarchy laid out properly.
Contact and Calendar Viewers

VCF and ICS Files

Two readers for the small files that carry people and dates between systems.

vCard Viewer Inspect every stored field on a contact card before importing it. ICS Viewer Calendar invites and subscriptions with every event listed out.
