Free online properties to JSON converter. Just load your properties file in the input field and it will automatically get converted to a JSON file. In the tool options, you can select the properties file format – either the classic (Java) properties format or a custom properties format. The custom properties format can be further adjusted to match all properties-like file formats. Additionally, you can change the format of the resulting JSON.

This tool converts properties files into JSON format. Properties files are simple plain-text files that are used to store configuration data as key-value pairs. They are commonly used in Java applications and their main advantage is that they define one property per line, making them very easy to read, edit, and parse. They are structured such that each key and value are separated by an equal sign or a colon. This tool parses the given properties file and creates an equivalent JSON representation of the properties. The key-value pairs in the properties file are converted into a hierarchical, nested structure of JSON objects and arrays. The tool supports both the classic (Java) and custom properties file formats. The classic properties file format uses the equals sign or a colon ("=" or ":") to separate keys and values, a dot "." to separate keys in nested objects and indexes in nested arrays. For example, a classic properties file "cat=Luna" is converted to a JSON object { "cat" : "Luna" }. Similarly, the properties file "cat.name=Luna" is converted to a JSON object containing another nested object { "cat" : { "name" : "Luna" } }, and the properties file "cat.0=Luna" is converted to a JSON object containing a nested array { "cat" : [ "Luna" ] }. If your properties file uses different separator symbols, you can switch to the custom properties file format and set the separators in the options fields. Specifically, you can set any symbol for separating keys and values, set any symbol for separating keys in the nested objects, and set any symbol for separating indexes in nested arrays. Sometimes, instead of dot separators, brackets are used for array indexes. For example, the properties file "[0]=Luna [1]=Oliver" represents a simple array [ "Luna", "Oliver" ]. As you can see, the square brackets are used for indexing array elements. Therefore, in the custom properties file options, you can choose to use brackets for array indexes and specify the left and right bracket symbols, such as "( and )" or "< and >". The resulting JSON can be formatted as well. In particular, you can add multi-level indentation to it with spaces or tabs, or it can be output in a compact format without indentation. If you need to do the reverse conversion and turn a JSON file back into a properties file, then you can use our Convert JSON to Properties tool. Json-abulous!

In this example, we convert a simple properties file that we're using for our Java application into a JSON file. The properties file contains key-value pairs and it uses the standard properties file format, with an equals sign separating keys and values and a dot separating keys of nested objects. The tool automatically detects these separators and generates a JSON object containing a nested object. The generated JSON file is prettified and printed to the output area with two spaces per indentation level.
In this example, we load a properties file containing information about a person and her interests. The file uses a variation of the classic properties file format where a colon instead of an equals sign separates keys and values. As the interests are zero-indexed, the program recognizes that it's an array and converts it into a nested JSON array. Additionally, it applies tab indentation to the output JSON for better readability.
In this example, we convert a properties file with custom separators into a JSON object. The properties file contains detailed information about a product, including its name, brand, price, rating, and features. It separates the keys and values with the greater-than symbol ">". It uses the underscore symbol "_" to separate object keys. And the array indexes are wrapped in square brackets "[ ]". By setting these symbols in the custom properties file format options, we're able to parse it and create a JSON object that contains all the keys and values as nested objects and arrays.
