How to open a .cshtml file

CSHTML files come from ASP.NET MVC, Blazor, and the usual advice — buy the software that made it — is rarely what you need just to look inside one. This page covers what the format is and how to open it in a browser tab.

What is a .cshtml file?

Razor View is a code format developed by Microsoft, first appearing in 2010. It is normally produced by ASP.NET MVC, Blazor.

The Razor syntax where @ switches between HTML and C# with no closing tag needed — the parser infers where code ends.

Open a .cshtml file in your browser

OpenAnyFile routes .cshtml to its syntax highlighter, which highlights the source with language-aware colouring and line numbers.

  1. Open the OpenAnyFile opener in this browser — nothing to download or sign up for.
  2. Drag your .cshtml file onto the drop zone, click to browse for it, or paste it with Ctrl+V.
  3. The extension is detected and the file is handed to the syntax highlighter.
  4. Your CSHTML opens on its own viewer page: the source with language-aware colouring and line numbers.
  5. Use fullscreen for a closer look, or download the file back out unchanged. Nothing is transmitted anywhere — the parsing happens in your own browser process.

What you can and cannot do with it here

Works

Viewing, inspecting and verifying. You get the source with language-aware colouring and line numbers. File details, exact byte size and the detected signature are always shown.

Does not work

Editing and re-saving. OpenAnyFile is a reader, not an editor — for changes you still need special software or an equivalent.

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 CSHTML files

Can I open a .cshtml file without installing special software?

Yes. OpenAnyFile's syntax highlighter runs in your browser, so you can read a CSHTML file with nothing installed. You get the source with language-aware colouring and line numbers. For full editing you still need the original application — this is a viewer, not an editor.

How can I tell what a .cshtml file actually contains?

The .cshtml extension carries no fixed signature, so the extension alone proves nothing. Opening it in OpenAnyFile shows the raw header bytes and detected type, which is the only reliable way to identify one.

Is it safe to open a CSHTML 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 .cshtml file, exactly?

Razor View — a text/x-cshtml format created by Microsoft since 2010. The Razor syntax where @ switches between HTML and C# with no closing tag needed — the parser infers where code ends.

Does the same viewer handle formats related to CSHTML?

Yes — the same engine also opens .html, .xml, .sql, 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 .cshtml file, it will open too:
