Works
Viewing, inspecting and verifying. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. File details, exact byte size and the detected signature are always shown.
How to open a .dta file
Opening a DTA file usually means tracking down special software. It does not have to. Here is what the format really is, and a browser-based way to read one right now.
What is a .dta file?
Stata Data File is a binary & system format developed by StataCorp, first appearing in 1985. It is normally produced by Stata, economics and epidemiology research.
Heavily versioned: a .dta written by a recent Stata will not open in an older one until it is explicitly saved down to that release's format.

Open a .dta file in your browser
OpenAnyFile routes .dta to its universal hex inspector, which inspects a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
- Drag your .dta file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
- The extension is detected and the file is handed to the universal hex inspector.
- Your DTA opens on its own viewer page: a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis.
- Use fullscreen for a closer look, or download the file back out unchanged. Works the same on Windows, macOS, Linux, Android and iOS, because it is just a web page.
What you can and cannot do with it here
Does not work
Full-fidelity rendering. This extension has no standard structure, so you get a byte-level inspection rather than a rendered view.
Your {ext} file stays on your device
The entire pipeline — detection, decoding, rendering — runs client-side. Your browser hands the bytes to a decoder compiled to WebAssembly, the result is drawn to the page, and that is the whole journey. No account is created, no file is stored, and no analytics event carries your filename. This is also why there is no size limit imposed by a server: the only ceiling is your own available memory.
Frequently asked questions about DTA files
Can I open a .dta file without installing special software?
Yes. OpenAnyFile's universal hex inspector runs in your browser, so you can read a DTA file with nothing installed. You get a byte-level hex and ASCII dump alongside the detected signature, exact size and type analysis. It will not replace the original application for editing, but it answers 'what is in this file' in seconds.
How can I check a file really is a DTA file?
Look at the first bytes rather than the extension. A genuine DTA begins with 3C 73 74 61 74 61 5F 64 74 61 (
Is it safe to open a DTA file online?
With OpenAnyFile, yes, because nothing is uploaded. The file is read locally through your browser's File API and never leaves your device, so there is no server copy to leak, log or retain. That matters most for the kind of file people are least willing to hand to a random converter site.
What is a .dta file, exactly?
Stata Data File — an application/x-stata-dta format created by StataCorp since 1985. Heavily versioned: a .dta written by a recent Stata will not open in an older one until it is explicitly saved down to that release's format.
Does the same viewer handle formats related to DTA?
Yes — the same engine also opens .dll, .doc, .exe, so you can compare related files without switching tools.

These open with the same engine, so if you have one of these sitting next to your .dta file, it will open too:
