Extract text from ASP.NET user controls (ASCX)
To convert ASCX user controls to another format, you need Microsoft Visual Studio or other Developer software.
To convert other file formats to the "ASP.NET User Control" file type, you need software like Microsoft Visual Studio or a similar tool.
The .ASCX file is an ASP.NET Web User Control file used to define custom, reusable UI components for web applications. These files store fragments of web pages, such as navigation bars, login forms, or footers, containing both front-end markup (HTML, CSS) and inline server-side code (C# or VB.NET). Developers typically create and manage .ASCX files using Microsoft Visual Studio.
The primary disadvantage of the .ASCX format is its rigid dependency on the proprietary Microsoft ASP.NET framework. Unlike standard web files, .ASCX files cannot be opened or viewed directly in a web browser; doing so will trigger an error. They must be hosted on an IIS (Internet Information Services) server and embedded into a parent ASPX page to compile and render properly. This makes sharing or reviewing the visual output of the component impossible for users without a full development environment.
Users often need to convert .ASCX files when migrating legacy web applications to modern frameworks like React or Angular. The best conversion targets are HTML or TXT, which allows you to extract the raw structural markup. Note that any server-side logic will be lost during this conversion, as standard HTML cannot execute ASP.NET backend code.
Because this file format requires an active server environment to generate a visual interface, it is notoriously difficult for standard online tools to convert visually. However, just drag and drop your file to identify the format, view it, and convert it when possible. convert.guru can inspect the .ASCX file, extract the embedded text and source code, and help you recover the underlying HTML content.
Convert.Guru analyzes your ASCX file, detects the exact format, and lets you read the text inside.
Users also converted ACSX, CS, ASPX, ASHX and AXD files.
If you want to convert ASCX file to ASPX, HTML, HTM, CSS, JS, PHP, ASP, JSP, JSPX, PY, RB or PL, you can use Microsoft Visual Studio or similar software from the "Reusable Web Component Source" category. In the File menu, look for Save As… or Export….
To convert RSS, CSS, CGI, SITEMAP, PL, WEBMANIFEST, JSON, JS, XML, HTML, ICO or HTM files to ASCX, try Microsoft Visual Studio or another comparable tool in the "Reusable Web Component Source" category.
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 ASCX converter.
