JSON is a text format used to represent structured data. APIs and applications commonly use it to exchange values such as names, settings, lists and nested objects.
Why JSON becomes hard to read
JSON can be valid even when it appears on one long line. A formatter adds indentation and line breaks without changing the underlying values.
Validate before debugging the data
The TheTecTricks JSON Formatter attempts to parse the text in your browser. If the syntax is invalid, it shows an error instead of silently changing the input.
Formatting and minifying are opposites
Formatting improves readability for people. Minifying removes unnecessary whitespace so the JSON is smaller for transport or compact storage.
