Convert data files (DAT) online for free
The converter easily converts your DAT files to various formats - free and online. No Microsoft Outlook or or other Data software needed.
To convert other file formats to the "Generic Data File" file type, you need software like Microsoft Outlook or a similar tool.
A .DAT file is a generic data container. Because developers use this extension for almost anything, it has no standardized internal structure. It could be plain text, a compiled game asset for Minecraft, a Windows Registry hive, or an MPEG video from an old Video CD. For more background on data files, see Wikipedia's Data file article.
The biggest problem with .DAT files is that your operating system has no idea how to open them. Double-clicking usually results in a frustrating "How do you want to open this file?" prompt. A very common and annoying occurrence is the winmail.dat file. This happens when Microsoft Outlook bundles attachments into a proprietary TNEF format, trapping standard PDF or DOCX documents inside a wrapper that non-Outlook email clients simply cannot read.
To make a .DAT file usable, you must analyze its internal header (its "magic bytes"). If it is an encapsulated winmail.dat file, you need to extract its contents to PDF or JPG. If it is a VCD video file, convert it to MP4 for modern playback. If it is pure text data, convert it to CSV. Drop your file here to view and convert it securely right in your browser. We will analyze the true format of your .DAT file and extract or convert it without installing extra software.

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DAT converter.
