Working with Source Code Files

Source code files are the building blocks of all software. They contain human-readable instructions written in programming languages like JavaScript, Python, Java, and hundreds more. Each language has its own syntax, conventions, and file extensions that help tools identify and process them correctly.

When working with code files, line numbers are essential for debugging, code reviews, and collaboration. Most error messages reference specific line numbers, making a viewer with line numbering invaluable. Syntax-specific features like proper indentation visibility and search help developers navigate complex codebases efficiently.

Configuration files (YAML, TOML, JSON, INI) are another common text-based format used by virtually every application. These files control settings, dependencies, and deployment configurations. Being able to quickly view and search through these files without installing specialized software saves time and streamlines workflows.

  • Source code comes in hundreds of programming languages and file formats
  • Line numbers are essential for debugging and code review
  • Configuration files (YAML, JSON, TOML) control application behavior
  • Log files provide runtime information for troubleshooting
  • File extensions help identify the programming language
  • Text-based files can be viewed in any text editor or viewer

Common Questions

What file types does the code viewer support?

Our viewer supports any text-based file including source code (JS, TS, Python, Java, C++, etc.), config files (YAML, TOML, JSON, INI), markup (HTML, CSS, XML, Markdown), logs, shell scripts, and plain text files. Basically any file that contains readable text.

How do I use this code viewer?

Drag and drop your file onto the upload area, or click to browse your device. You can also paste a URL to a text file and click "Load". Your code will appear instantly with line numbers and search capabilities.

Is my code secure?

Absolutely! Your files never leave your device — everything is processed locally in your browser. We have no servers that store or process your content.

Can I search within the file?

Yes! Use the search box in the toolbar to search for specific text. Matches are highlighted and you can navigate between them using the up/down arrows. The current match is highlighted in a different color.

Does the viewer show line numbers?

Yes! All files are displayed with line numbers on the left side. This makes it easy to reference specific lines, especially for log files and source code.

What statistics are shown?

The viewer shows file size, total lines, character count, word count, number of empty lines, and the detected programming language based on the file extension.

Can I copy or download the file?

Yes! Use the Copy button to copy the entire file contents to your clipboard, or the Download button to save the file to your device.
