Properties To Toml: An Overview of Key Concepts

Developers often encounter the need to manage and store application configurations. Properties files in Java are one of the most common ways to store configuration data. However, as the application evolves, managing and handling large properties files can be challenging. Fortunately, Toml was created as a better alternative to properties files. Properties To Toml is a handy tool that allows you to convert single or multiple Java properties files to Toml format with ease. In this article, we will discuss the concept and how Properties To Toml works, as well as its scenarios, key features, misconceptions, and FAQs.

Properties To Toml: How It Works

Properties To Toml is a command-line tool that works by converting Java properties files to Toml format. The tool supports different command-line arguments, such as the source directory containing properties files, the target directory to store the converted files, and the delimiter used in the properties files. Here’s an example command to convert a single file:

java -jar prop2toml.jar

You can also use Properties To Toml tool in He3 Toolbox ( ) easily.

The tool will create a corresponding TOML file in the same directory as the properties file. For instance, given a file, the corresponding TOML file will be file.toml. You can also convert multiple properties files by providing the source directory containing the properties files and the target directory for the converted files.


Properties To Toml is ideal for handling large properties files that become difficult to manage over time. It helps developers reduce the complexity of configuration files and allows them to parse and read configurations more easily. The tool is especially useful for developers building applications that use Toml as the primary configuration file format.

Key Features

Properties To Toml has several key features that make it a valuable tool for developers. Here is a table of the essential features:

Command-line toolProperties To Toml is a command-line tool that runs on the terminal.
Multiple file processingThe tool can process multiple files in a directory.
Customizable delimiterThe tool allows you to specify the delimiter used in the properties files.
Automated conversionsThe tool automates the conversion of properties files to Toml format.


One common misconception about Properties To Toml is that it only works with Java properties files. The tool can also process other properties files, such as those generated by .NET and Python applications. Another misconception is that the tool requires extensive knowledge of Toml syntax to use. Properties To Toml handles the conversion process automatically and does not require any Toml expertise from the user.
