HTML to ASP Converter

Transform HTML into ASP/ASP.NET server-side code

About HTML to ASP Converter

Use this HTML to ASP converter to transform static HTML into Classic ASP (VBScript) or ASP.NET (C#) server-side code. Generate Response.Write statements, string variables, or reusable functions/methods from existing HTML templates without rewriting everything by hand.

Key Features

  • Classic ASP output: Create VBScript-based Response.Write blocks, string variables, or functions.
  • ASP.NET output: Generate C# code-behind style Response.Write, string, or method-based HTML rendering.
  • Multiple formats: Choose between inline output, stored variables, or reusable rendering functions.
  • Automatic escaping: Quotes and special characters are escaped correctly for VBScript or C#.
  • Line break handling: Preserve original HTML formatting with vbCrLf or \n as appropriate.
  • Real-time conversion: Output updates automatically as you type or upload new HTML.

How to Convert HTML to ASP/ASP.NET

  1. Paste or upload HTML: Insert HTML markup or upload an .html file from your design.
  2. Select ASP version: Choose Classic ASP (VBScript) or ASP.NET (C#) depending on your project.
  3. Pick output format: Use Response.Write for inline rendering, String Variable for manipulation, or Function/Method for reusable templates.
  4. Copy or download: Copy the generated code into your .asp/.aspx file or download it for later.
  5. Test on server: Run the page in IIS or your ASP/ASP.NET environment to verify the output.

Examples

Example 1: Classic ASP Response.Write

A simple HTML snippet becomes:

<%
' Classic ASP - Response.Write Output
Response.Write "<h1>Hello</h1>" & vbCrLf
Response.Write "<p>Welcome to our site.</p>" & vbCrLf
%>

Example 2: ASP.NET string variable

In ASP.NET mode with string variable output, HTML is embedded in a C# string and written once:

<%@
    Page Language="C#" %>
<%
// ASP.NET - String Variable
string htmlContent = @"
<h1>Hello</h1>
<p>Welcome to our site.</p>";

Response.Write(htmlContent);
%>

When to Use HTML to ASP

  • Legacy maintenance: Keep Classic ASP apps up to date by converting designer HTML into server-side code quickly.
  • Template generation: Build reusable header/footer functions from static HTML layouts.
  • Email templates: Embed HTML emails as ASP/ASP.NET strings or functions.
  • Migration paths: Move HTML prototypes into production ASP/ASP.NET projects.

FAQ

Does the tool support Razor (.cshtml)?

No. This converter focuses on Classic ASP (.asp) and ASP.NET Web Forms-style pages (.aspx) using C#.

Will my dynamic server-side code be preserved?

The converter is designed for static HTML markup. Any existing server-side code blocks should be added manually after conversion.

Can I edit the generated code?

Yes. The output is plain VBScript or C# that you can freely edit inside Visual Studio, VS Code, or your preferred IDE.

Is my HTML uploaded anywhere?

No. All HTML to ASP/ASP.NET conversion runs in your browser. Templates are never sent to external servers, which is important for proprietary layouts and intranet apps.

Privacy & Security

All processing is done client-side. No HTML, ASP, or ASP.NET code is stored or logged, so you can safely use this converter for internal or client work.
