JSON Formatter — developer utilities, encoders and data format tools
The JSON Formatter cleans up your JSON in three ways: it validates the input, formats it with readable indentation, or minifies it into a single compact line. You choose the indentation style, from two spaces to four spaces to a tab. Invalid input shows the parser error so you can fix it immediately
