This is the list of 5 free code formatter software to beautify source code. Using these software, you can easily format your code to make it look good. These software are dedicated software to format the source code of a lot of programming as well as scripting languages. You will find a lot of options in them regarding indent, formatting styles, bracket styles, line, function, keywords formatting and many other options. When you choose an operation, all the changes in the code will appear in real-time. In this list, I have also added a plugin of Notepad++ to do the same. These software supports all popular programming languages like Java, C, C++, C#, Scala, Pascal, and a lot more.

In some of these software, you can even process multiple source code files together. So you can also do batch processing to format source code in multiple files.

Within the similar context, we have covered a Windows 10 code indenter app, a code editor, and an online tool to format SQL. And now, here in this curated list, I shall be talking about some dedicated code formatter software.
