Free online JSON syntax highlighter. Just load your JSON in the input field and its syntax will automatically get color-coded in the output field. In the tool options, you can select, which parts of the JSON to highlight and add line numbering to it as well. Created for developers by developers fromteam Browserling.

This tool highlights the syntax of JavaScript Object Notation (JSON) files. It uses different colors for different elements of the object, making it easier to navigate, understand, and read the code. Specifically, text data in quotes is displayed in one color; numbers, logical values, such as "true" and "false", and the null element "null" use another color; and structural elements, such as brackets "{ }" and "[ ]", commas ",", and colons ":" use a third color. In addition to syntax highlighting, the tool can also identify JSON syntax errors and determine their exact location in the file. For example, if the program finds an unclosed quote on a text line, it will report the error and indicate the line number and position where the error is located. This way you can quickly find and fix all JSON mistakes. To quickly navigate the file, you can enable line numbers in the options. You can also display invisible characters, such as tabs and newlines. To track the JSON structure and nested objects and arrays, you can use the brackets-matching highlighting option, which highlights the opening and closing brackets when the cursor is near them. You can also enable highlighting of the current line where the cursor is located. This helps you focus on the line you are currently working on. The tool currently uses a dark theme, but will soon support more color syntax themes. Json-abulous!

In this example, we showcase a simple JSON structure containing various data types. The program highlights strings, numbers, boolean values, arrays, and objects in different colors, making it easy to navigate through the file.
This example demonstrates a JSON structure with an error. The program quickly identifies the error and prints its exact location. To easily find and fix it in the file, we activate the "Show Line Numbers" checkbox in the options. This allows us to quickly jump to the line containing the error.
In this example, we load a more complex data structure with nested objects and arrays. In addition to syntax highlighting, we visualize invisible tabs, spaces, and line breaks. This helps us notice that the file sometimes uses spaces for indentation and sometimes tabs. It also contains unnecessary spaces at the end of lines, which is a bad programming style. While such JSON formatting is allowed, it is recommended to use a uniform format with no trailing spaces. Fortunately, this JSON format can be easily fixed in our "Prettify JSON" tool.
You can pass input to this tool via ?input query argument and it will automatically compute output. Here's how to type it in your browser's address bar. Click to try!
