About FormatPeek

FormatPeek makes difficult office file formats easier to inspect from a modern browser.

Why we built it

People regularly receive project plans, saved emails, diagrams and reports created by specialist desktop software they do not own. FormatPeek provides focused viewers for those moments without requiring an account or a permanent cloud workspace.

Our approach

Each viewer focuses on the information people need from its source format. MPP files include project views and scheduling details. MSG and EML files are presented as readable emails with message details, headers and attachments.

Privacy by design

MSG and EML files stay inside the browser. MPP files are processed temporarily and deleted from the parser immediately after parsing. FormatPeek does not offer permanent file storage.
