Convert Filenames to snake_case or kebab-case

You’ve probably Googled “Convert Filenames to snake_case or kebab-case” because you’re staring at a mess. Maybe it’s a batch of photos from a vacation, a set of downloaded assets, or files you’ve exported from some software, and they all have those infuriatingly inconsistent, space-filled, or oddly capitalized names. “My holiday photo 1.JPG,” “project-document FINAL v2.docx,” “image 005.PNG.” It’s not just ugly; it’s impractical. These kinds of filenames can cause problems with scripting, command-line tools, and even some web frameworks that expect cleaner, more predictable naming conventions. You’re not alone in this frustration, and thankfully, there’s a straightforward solution.

Why snake_case and kebab-case Dominate File Naming

Let’s cut to the chase: why should you care about converting to snake_case or kebab-case? It boils down to consistency, compatibility, and clarity. snake_case, where words are separated by underscores (like my_awesome_image.jpg), is particularly popular in programming, especially in Python and Ruby. Many systems and APIs are built assuming this format. On the other hand, kebab-case, using hyphens (like my-awesome-image.jpg), is prevalent in web development, particularly for CSS class names, HTML IDs, and URL slugs. Both formats eliminate spaces, which can be problematic in various contexts (especially in URLs or command-line arguments where spaces often require escaping), and they use lowercase letters, avoiding case-sensitivity issues that can trip up different operating systems or tools. Choosing one and sticking to it for a project or a set of files makes your work look professional and significantly reduces the chances of encountering unexpected errors when you try to use those files later. It’s a small change that pays dividends in saved time and reduced headaches.

The Pitfalls of Inconsistent File Naming

Think about a typical workflow. You download a dozen images, and they come out as “IMG_20231027_153005.jpg,” “Screenshot (1).png,” “photo-copy.jpeg,” and “Final Report Draft.pdf.” If you’re trying to write a script to process these images, or even just move them into a structured folder system, you’re immediately facing hurdles. Spaces in filenames often require careful quoting in shell scripts. Mixed capitalization can lead to errors if your system or the tool you’re using is case-sensitive. Non-alphanumeric characters (like parentheses or even just different types of hyphens) can also be problematic. When you’re dealing with just a few files, you might manually rename them. But what if you have fifty? Or a hundred? Or a thousand? Manual renaming becomes an exercise in futility. This is where batch processing tools come in, and a good converter needs to handle the common transformations reliably. You might also find yourself needing to generate placeholder text for design mockups; for that, the OptiPix Lorem Ipsum Generator is surprisingly handy.
