Do you need the ability to check if your ePub file passes the ‘epub checker’ validation tool? Rather than upload your file to one of the various epub checkers on the web, you should install and run it on your own computer. Why? Because if you are having any errors after you try to upload your formatted ebook, chances are, it didn’t pass the epub checker.
It’s a bit confusing when you try to follow the fragmented instructions you’ll find around the web. So I wanted to share the exact process I went through to successfully install the ability to validate an epub on my own PC:
- Download and install Java if it isn’t already on you computer
- Modify your PATH to enable the ability to run Java from your command line/prompt. This is exactly how mine appeared (it’ll make sense after you view this tutorial): ;C:Program Files (x86)Javajre6bin
- Download ePub checker binary (version I have is 3.0.1)
- Unzip the file and place all the files in a root directory on your c: drive (ie. /epub)
- Put the .epub file you want to check in the same directory (ie. /epub)
- Run your command prompt application (type command on the start bar)
- Change directory to /epub (by using the basic command cd until you get to the root directory (c:/) and then type cd epub.
- To run the epub checker, you will need to yype something similar to this on the command line (it will vary depending on the version of epubcheck and your epub file name): java -jar epubcheck-3.0.1.jar filename.epub
Here’s a screenshot of how it looks when you have a successful epub check (in this case, the file I am checking is entitled ‘gaddafi.epub’).
If you are still struggling getting it to work, let me know because I can post a YouTube video to walk you through the process and will post the link when it’s available.
