Json highlighter tool What is a json highlighter?
This tool hilites the syntax of JavaScript Object Notation (JSON) files. If you load JSON that has syntax errors, it will highlight the position of the error. You can also make it indicate invisible characters such as tabs and newlines, then toggle line numbers of JSON lines, then highlight matching brackets for easier visibility, and also highlight the current line so you can easier tell which line your cursor is on. It currently uses a dark theme but soon it will support more color syntax themes.
